how fast yachts can go

How Fast Is A Yacht? 3 Types Checked (With 9 Examples)

Different types of boats require various speeds for maneuvering in various water types and for doing diverse activities.

Depending on what you want to do with your vessel, you might need it to travel at a certain speed.

How Fast Are Yachts?

Yachts differ in speeds depending on the type of boat, with mega-yachts and ocean sport boats being the fastest (at over 30 MPH), cruisers, and deck boats falling second (at an average speed of 23 MPH), then pontoons, and sailboats averaging 10 MPH.

Here’s everything you should know about how fast yachts can go:

First, How do we Define a “Yacht”?

First, let’s make sure we are talking about the same thing. After all, different types of boats sail at different speeds.

Yachts are boats (sail or power) used for racing, cruising, or just for pleasure.

It is a general term, which makes the question, “What is the average speed of a yacht?” a complicated one to answer.

Yachts can range in length between mini yachts, measured at 23 feet (seven meters), to superyachts, which are at least 78 feet long.

Before covering how fast each type of yacht can travel, here is a quick and dirty list of yachts that this article will cover:

• Has a single deck above the hull with below-deck living quarters. They are normally sleek and sporty.
• Control station, seating, and lounge space.
• It is a large, recreational, and motor-powered boat with multiple decks and a larger interior main deck than a flybridge.
• A yacht that has an enclosed living space and that is longer than 80 feet.
• A yacht that is built and used for fishing. Normally has a large cockpit to store fishing essentials. It is often faster than regular motor-yachts to get to the fishing grounds and back quickly.
• Pontoon boats lie flat on the water, balancing on two (or three) aluminum tubes, instead of having a V-shaped hull like deck boats. This makes them more stable for entertaining large groups of people.
• Primarily uses sails for propulsion instead of a motor (though most have a motor for back-up or to assist with the sails). Most are used for sport, but there are quite a few leisure sailing boat clubs and organizations these days.

The yachts that fall into categories 1 – 6 are motorized but are all smaller than superyachts.

For the rest of the article, the term “motorized yachts” or “powerboats” will refer to one of these.

How Fast Does my Yacht Need to be?

The answer to this question depends on what you want to do with your yacht.

If you’re a fisherman that needs to only troll through calm waters, it might be best if your boat travels with a top speed of around 15 MPH.

But if you’re looking to hit the open waters and speed around with the wind in your hair, you might want something a bit faster than that.

While you’re shopping for boats, and considering the top speeds for each type, ask yourself:

• What activities will you be doing on your boat?
• What sort of waters will I be traveling on?
• What activities will I be doing, which will utilize its top speed?

How Does the Speed of a Boat Affect its Fuel Consumption?

This depends on the type of boat you use. For ease of reference, the Formula 240 Bowrider speedboat (a 24-foot motorboat) is a good example of an average boat.

When cruising at 7 MPH, it consumes approximately three gallons an hour. When you double the speed, it consumes double the fuel (seven gallons an hour at 15 MPH). At 30 MPH, it will use about 11 gallons.

A general rule of thumb is that mid-range speed will offer the best fuel efficiency.

There is no need to merely putter around the water to save money.

How Fast Should I Go on a Yacht?

Unfortunately, there aren’t any speed limit signs out in the open water. Because of that, sailors and boaters have to calculate the speed limit depending on at least three different factors: the time of day, the type of boat, and the type of waterway.

The speed limit for boats is rarely a specific numerical figure. Instead, look for safety concerns, warning signs (like “No Wake Zones”), and rules often posted on the docks.

Watch out for “No Wake Zones,” which can cost a hefty fine if you are caught in violation and can be dangerous to people, animals, and property in the area. Most speedboats and other motorboats can cause a wake in as little as 5 MPH.

If you are close to a river, shore, or populated areas, you have to tread on the side of caution. However, once you are out in open water (like the ocean or a large lake with no one around), you can test out your boat’s top speed.

Make certain that you can:

• See an open pathway of water.
• See no obstacles (people, vehicles, animals, jetsam, or debris)
• Have observed the rules posted at the dock or pier

What are the Top 10 Fastest Yachts on the Market Today?

This list will consist of a variety of motorized yachts, powerboats, and superyachts.

Superyachts are so big; they need a more powerful engine.

For example, the Astro by Baia Yachts uses triple 2,430hp MTU engines and can put out 7 290 hp at its max.

It can go about 57 MPH or 50 knots! And that’s not even fast enough for our top ten list!

10) “The Chato” (built by Baglietto)

The Chato is an 84.61-foot yacht with accommodations for up to six people.

It is an all-aluminum speed demon with two MTU diesel engines, which propel it forward at a whopping 65.59 mph.

9) “Ermis 2 ” (by McMullen & Wing)

The Ermis is a 123.23-foot yacht made of carbon-fiber to make it both light and sleek.

The triple waterjets (MTU 16V 4000 M90 series) push it forward with 11,000 hp, making it fly across the water at a top speed of 63.29 mph.

8) “Black Bullet” (by Otam)

The Black Bullet is an 83.7-foot yacht, is the fastest yacht in the Otam 80 series.

It can accommodate two crew and six guests and moves quickly with four diesel engines.

How quick? 66.7 mph quick.

7) “Oci Ciornie” (by Palmer Johnson)

The Oci Ciornie is an 82-foot yacht that uses a 4,600 horsepower AVCO Lycoming gas turbines, an Arneson surface drives, and twin 1,800 horsepower MTU 16V 2000 M90 engines to propel it forward to 69 mph.

Vroom, vroom.

6) “The Brave Challenger” (by Vosper)

This yacht tops out at 69 mph because of her three gas turbine engines. Together, they generate about 13,620 horsepower. In addition to that, she also has two conventional engines to help her move around the water a little easier when she needs to cruise at a slower speed.

Originally named Mercury, she was built for Stavros Niarchos, a Greek shipping tycoon.

5) “Kereon” (the second boat on our list by AB Yachts)

The Kereon is an 88.6-foot yacht that can top out at 71 mph because of its three diesel engines. She has three 2,250 horsepower CRM diesel engines that were designed by Angelo Arnaboldi, a naval architect.

The Kereon can accommodate six guests in three cabins. She also has a massive fuel tank, which can hold 3170 gallons of fuel. That means she can go approximately 900 nautical miles on one tank of fuel.

4) “Gentry Eagle” (by Vosper Thornycroft)

The Gentry Eagle is a 111.88-foot yacht built for and by Tom Gentry (who worked with Vosper Thornycroft). If his name sounds familiar to you, it’s probably because he set almost every powerboat speed record today. He won the Blue Riband (the award for the fastest passage across the Atlantic) with a record time of 62 hours and seven minutes. The Gentry Eagle beat Richard Branson’s record by 23%.

Talk about fast.

It tops out at 73.64 mph.

3) “Galeocerdo” (by Rodriquez)

The Galeocerdo is a 118.1-foot yacht powered by three Vericor TF50 gas turbines (which drive three Rolls-Royce Kamewa water jets).

The Galeocerdo tops out at 74 mph.

2) “The World Is Not Enough” (by Millenium Super Yachts)

This yacht is a 138.45-foot yacht that can accommodate 10 guests and can go 77.1 mph.

It is propelled by two Lycoming gas turbines and two Paxman diesel engines.

1) “Foners” (by Izar)

The Foners is a 136.15-foot yacht made specifically for King Juan Carlos of Spain’s royal yacht. It was also built for speed with two 1,280 horsepower MAN engines.

But that’s not all, and it also has three Rolls Royce 6,700 horsepower gas turbines that drive three Kamewa water jets.

How fast does it go? It tops out at 80.5 mph!

What’s the Fastest Motorized Yacht in the World?

The record for the fastest boat was set at 317.6 MPH .

Ken Warby was using a speedboat (powered by a jet engine instead of a regular boat motor) called the “Spirit of Australia.”

This was not included on the fastest yacht list because of its unique circumstances.

Final Thoughts:

Choosing the right yacht for you and your needs is a big decision. Make sure you know what you will do with your boat before you buy a boat strictly built for speed.

The bragging rights in owning a boat that can go 80 mph on the water is great.

But if you are only going to use it for trolling or fishing, it would be a waste on your pocketbook and for the boat.

Sail GP: how do supercharged racing yachts go so fast? An engineer explains

Sailing used to be considered as a rather sedate pastime. But in the past few years, the world of yacht racing has been revolutionised by the arrival of hydrofoil-supported catamarans, known as “foilers”. These vessels, more akin to high-performance aircraft than yachts, combine the laws of aerodynamics and hydrodynamics to create vessels capable of speeds of up to 50 knots, which is far faster than the wind propelling them.

An F50 catamaran preparing for the Sail GP series recently even broke this barrier, reaching an incredible speed of 50.22 knots (57.8mph) purely powered by the wind. This was achieved in a wind of just 19.3 knots (22.2mph). F50s are 15-metre-long, 8.8-metre-wide hydrofoil catamarans propelled by rigid sails and capable of such astounding speeds that Sail GP has been called the “ Formula One of sailing ”. How are these yachts able to go so fast? The answer lies in some simple fluid dynamics.

As a vessel’s hull moves through the water, there are two primary physical mechanisms that create drag and slow the vessel down. To build a faster boat you have to find ways to overcome the drag force.

The first mechanism is friction. As the water flows past the hull, a microscopic layer of water is effectively attached to the hull and is pulled along with the yacht. A second layer of water then attaches to the first layer, and the sliding or shearing between them creates friction.

On the outside of this is a third layer, which slides over the inner layers creating more friction, and so on. Together, these layers are known as the boundary layer – and it’s the shearing of the boundary layer’s molecules against each other that creates frictional drag.

A yacht also makes waves as it pushes the water around and under the hull from the bow (front) to the stern (back) of the boat. The waves form two distinctive patterns around the yacht (one at each end), known as Kelvin Wave patterns.

These waves, which move at the same speed as the yacht, are very energetic. This creates drag on the boat known as the wave-making drag, which is responsible for around 90% of the total drag. As the yacht accelerates to faster speeds (close to the “hull speed”, explained later), these waves get higher and longer.

These two effects combine to produce a phenomenon known as “ hull speed ”, which is the fastest the boat can travel – and in conventional single-hull yachts it is very slow. A single-hull yacht of the same size as the F50 has a hull speed of around 12 mph.

However, it’s possible to reduce both the frictional and wave-making drag and overcome this hull-speed limit by building a yacht with hydrofoils . Hydrofoils are small, underwater wings. These act in the same way as an aircraft wing, creating a lift force which acts against gravity, lifting our yacht upwards so that the hull is clear of the water.

While an aircraft’s wings are very large, the high density of water compared to air means that we only need very small hydrofoils to produce a lot of the important lift force. A hydrofoil just the size of three A3 sheets of paper, when moving at just 10 mph, can produce enough lift to pick up a large person.

This significantly reduces the surface area and the volume of the boat that is underwater, which cuts the frictional drag and the wave-making drag, respectively. The combined effect is a reduction in the overall drag to a fraction of its original amount, so that the yacht is capable of sailing much faster than it could without hydrofoils.

The other innovation that helps boost the speed of racing yachts is the use of rigid sails . The power available from traditional sails to drive the boat forward is relatively small, limited by the fact that the sail’s forces have to act in equilibrium with a range of other forces, and that fabric sails do not make an ideal shape for creating power. Rigid sails, which are very similar in design to an aircraft wing, form a much more efficient shape than traditional sails, effectively giving the yacht a larger engine and more power.

As the yacht accelerates from the driving force of these sails, it experiences what is known as “ apparent wind ”. Imagine a completely calm day, with no wind. As you walk, you experience a breeze in your face at the same speed that you are walking. If there was a wind blowing too, you would feel a mixture of the real (or “true” wind) and the breeze you have generated.

The two together form the apparent wind, which can be faster than the true wind. If there is enough true wind combined with this apparent wind, then significant force and power can be generated from the sail to propel the yacht, so it can easily sail faster than the wind speed itself.

The combined effect of reducing the drag and increasing the driving power results in a yacht that is far faster than those of even a few years ago. But all of this would not be possible without one further advance: materials. In order to be able to “fly”, the yacht must have a low mass, and the hydrofoil itself must be very strong. To achieve the required mass, strength and rigidity using traditional boat-building materials such as wood or aluminium would be very difficult.

This is where modern advanced composite materials such as carbon fibre come in. Production techniques optimising weight, rigidity and strength allow the production of structures that are strong and light enough to produce incredible yachts like the F50.

The engineers who design these high-performance boats (known as naval architects ) are always looking to use new materials and science to get an optimum design. In theory, the F50 should be able to go even faster.

The top 10 fastest superyachts in the world

Despite their larger size, superyachts can still reach an impressive speed on the water – as this official list of the world’s fastest superyachts shows. For over 20 years, the 41.5-metre Izar -built yacht Foners had been outpacing her contenders with top speeds of 70 knots – equivalent to 80 miles per hour – and lay claim to the world's speediest superyacht title. But in 2023, a new contender swooped in and cinched first place. Described as a "hyper muscle yacht", the Bolide 80 entered the scene with a rapid 73-knot maximum speed.

Their challengers are not far behind. For adrenaline-seekers with a need for speed, get your pulses racing with our definitive list of the quickest superyachts on the water.

Bolide 80 | 73 knots

Built in 2023, the 24.9-metre Bolide 80 model holds the title for the fastest superyacht in the world, narrowly pipping the long-time champion, Foners , to the post. The "hyper muscle yacht" hits a blistering top speed of 73 knots with propulsion deriving from triple MAN 12 V 2000 diesel engines, each delivering around 2,000 horsepower. In terms of range, she is predicted to deliver 200 nautical miles at maximum speed, with a range of 345 nautical miles at a cruising speed of 55 knots.

Everything about the yacht's design has been carefully considered, from its aerodynamic-engineered exterior to the way it harnesses foiling technology. At the intersection of performance and avant-garde design, the Bolide 80 is able to hit the impressive top speed thanks to its "multi-stepped" planing hull that generates low frictional resistance. In terms of fuel consumption, she consumes 11 litres per mile at 40 knots, 13 litres per mile at 55 knots and 16 litres per mile at 70 knots.

The interior configuration on hull one – a collaboration between Stefano Faggioni and Victory's internal design team – features an owner's cabin in the most forward part of the hull. Meanwhile, the main saloon is located on the lower deck amidships, which can be transformed into a second cabin if needed.

Yachts for sale, more stories, foners | 70.1 knots.

Clocking in at a thrilling 70.1 knots, the 41.5-metre Foners once raced to the top spot as the world’s fastest superyacht but is now narrowly trumped by the Bolide 100. She’s been difficult to catch up with, having maintained her position since her delivery in 2000. 

Her zippy speed is produced by two 1,280hp MAN engines coupled with three Rolls Royce 6,700hp gas turbines that drive three KaMeWa water jets. But she is not just about speed; her interior, designed by Studio Spadolini is quite literally fit for a king. Originally built by Spanish shipyard Izar as the King of Spain’s royal yacht , the DLBA-designed Foners features interiors finished in elegant gloss sycamore wood panelling with stitched tan leather detailing. She can accommodate eight guests and six crew on board, and her superstructure has been lined with Aramid fibre for the express purpose of making it bullet proof. There is a formal dining room indoors, while the deck spaces are vast offering plenty of opportunities for al fresco entertaining. At a cruising speed of 12 knots, she has a range of 1,800 nautical miles.

Galeocerdo | 65 Knots

The sleek lines and futuristic design of Rodriquez Yachts’ Galeocerdo is the result of exhaustive research and design development programme by Wally founder Luca Bassani. Created with the aim of maintaining high speeds in rough seas, the 36-metre Wally Power 118 superyacht was launched in 2003 following tank testing at the SSPA facility in Goteborg, Sweden, and wind tunnel testing at the Ferrari facility in Maranello, Italy. Lazzarini Pickering Architetti and Intermarine also collaborated on the design of Galeocredo .

Galeocerdo is driven to a top speed of 65 knots by three Vericor TF50 gas turbines, each driving a Rolls-Royce Kamewa water jet. The titanium exhaust system is lightweight while extremely resistant to the high temperatures generated by the gas turbines, and can muster up to 16,800hp. At a cruising speed of 45 knots, she can cover a range of 1,500 nautical miles. Her interiors offer room for six guests and six crew on board.

Kereon | 62.3 Knots

Launched in 2004 by Italian yard AB Yachts, Kereon can blast through waves at a top speed of 62.3 knots. This punchy performance is made possible by a triple 6,300hp CRM diesel engine set-up fitted to a fast planing hull designed by naval architect Angelo Arnaboldi . Inside Kereon can accommodate up to six guests in three cabins, while her 12,000-litre fuel tank means a maximum range of 900 nautical miles is possible at her fast cruising speed of 50 knots. The 35.7-metre superyacht features sharp exterior lines and a distinctive metallic silver superstructure that contribute to her sporty allure.

Oci Ciornie | 60 Knots

Prolific naval architect Don Shead teamed up with American yard Palmer Johnson and Dutch shipbuilders Vripack in 1998 to create Oci Ciornie . This aluminium-hulled speed machine was fitted with twin 1,800hp MTU 16V 2000 M90 engines, a 4,600hp AVCO Lycoming gas turbine and Arneson surface drives for a staggering top speed of 60 knots.

Her interiors can accommodate up to eight guests in three cabins consisting of a master suite, double cabin and twin room with a pair of pullman berths. The deck saloon and forward outside spaces are all located on one level for a streamlined look, and the interior of the main saloon takes design cues from vintage aircraft design. The 25-metre superyacht can also accommodate two crew on board.

AB 100 | 60 knots

Forming part of AB Yachts ' 30-metre AB100 series, sisterships Yunga and El Mirlo secure 10th place in the list of the fastest superyachts in the world. The sportfly models were the first to be launched since the series was redesigned in 2021 and boast impressive credentials: a top speed of 60 knots, cruising speed of 37 knots, and maximum cruising range of 550 nautical miles at 45 knots, with power coming from a pair of MTU diesel engines. The AB100 series is known for its "breathtaking" speeds upwards of 50 knots, which the Viareggio-based shipyard claims can be reached "almost without noticing". Interior design on both yachts is owed to Archea Associati with accommodation for up to 10 guests across four staterooms.

Azimut Atlantic Challenger | 60 knots

Designed purely for the purposes of collecting the Blue Riband award, the Azimut Atlantic Challenger was launched by Benetti in 1988 with exterior details by Pininfarina . The 26.82-metre aluminium monohull can reach a top speed of 60 knots under the power of four CRM diesel engines offering 7,400hp. At a cruising speed of 40 knots, she has a range of 3,000 nautical miles. Unfortunately, her attempt to procure the Blue Riband shortly after her launch in 1988 was ultimately fruitless.

• Builder: Benetti
• Delivery year: 1988
• Length Overall: 26.82 m
• Beam: 7.5 m

Brave Challenger | 60 Knots

Powered by three Rolls-Royce Proteus gas turbines totalling 13,500hp, the 31-metre Brave Challenger has proven top speeds of over 60 knots and can achieve higher speeds using its alternative Vosper-developed high-speed propellers.

Built by Vosper Ltd in Portsmouth in 1961, Brave Challenger is the only surviving example of the Brave Class fast-patrol design that was designed and built for the Royal Navy. Built alongside the Royal Navy’s HMS Brave Borderer and HMS Brave Swordsman , Brave Challenger was completed with a special consent of the Admiralty and Royal Navy to be equipped for private use.

First acquired by owner W.G. Haydon-Baillie in 1979, Brave Challenger was rebuilt to flagship standard at a purpose-built facility as part of the Haydon-Baillie Aircraft and Naval Collection in Southampton over a period of 10 years and 2.2 million man hours from 1979 – 1989. From 2017 – 2021, Brave Challenger underwent a full restoration by the Haydon-Baillie Maritime Heritage Team at the superyacht refit yard Trafalgar Shipyard in Portsmouth. Its dedicated support base now includes 54 spare Rolls-Royce Proteus gas turbine engines, extensive spares, 10 spare V-Drive gearboxes and 12 spare propellers.

"Brave Challenger ’s speed of 60-plus knots was officially recorded under Lloyds Supervision over the Measured Mile off Portsmouth, UK – and is fully repeatable at all times as part of its design and everyday operating potential," according to owner W.G Haydon-Baillie. "It is often considered that only the fastest yacht speeds that are officially recorded and are not one-off events – and are fully repeatable as part of the yacht's design and everyday operating potential are relevant to include in the top 10 fastest claims."

The 13 Fastest Superyachts in the World

These boats prove that size doesn't have to mean slow..

• Share This Article

When American businessman John Staluppi embarked on his yachting journey, it was to break records. He wanted his first yacht to be the first boat over 100 feet to exceed 30 knots, or 34.5 mph. He achieved it with the 118-foot For Your Eyes Only, delivered in 1985. It was also the first motoryacht in the US to have a combination of MTU diesel engines with water-jet propulsion.

His second yacht would smash all previous records. Delivered by Heesen in 1988, Octopussy fulfilled the Bond enthusiast’s aim to break the then 50-knot barrier with a top end of 53.17 knots (61 mph)—a speed that every other shipyard at the time said couldn’t be done. Octopussy  immediately entered the record books as the world’s fastest yacht.

“That record was important to me because when you pull into any place there’s always a bigger boat or a prettier boat, but there aren’t many people who can say, ‘Hey, this is the fastest yacht in the world,’” Staluppi told Robb Report .

Heesen’s latest delivery, the 197-foot Ultra G , is one of the Dutch yard’s fastest projects these days, with a propulsion package totaling 22,000 horsepower, including four water jets that deliver a top speed of 37 knots (42.57 mph).

Of course, 43 mph is a paltry number compared to many of the yachts on this list, including the new Bolide 80. That Italian stallion, which will make its debut at the Monaco Yacht Show, runs at a blistering 84 mph. It shows that speed, even in the large motoryacht category, is very much alive.

Here are 13 of the fastest motoryachts, past and present, that have ever been on the water.

1. Bolide 80 | 84 mph

Victory Marine calls the Bolide 80 its first “Hyper Muscle Yacht,” which will be part of a limited-edition series from 60 to 170 feet. Designer Brunello Acampora and his tema of engineers pulled out all the stops on this 80, creating a full-carbon-fiber boat with more than 6,000 horsepower. The multi-stepped hull helps propel the Bolide to its top speed of 70 knots (84 mph), while accomplishing the seemingly impossible task of burning about half the fuel of a much smaller flybridge motoryacht at lower cruising speeds. The designer took care to give the Bolide a streamlined profile, with aerodynamic shapes to reduce resistance. The interior includes the captain’s cabin, a full-sized galley, open salon, and a forward owner’s area with a bedroom, en suite and wardrobe area. It will make its global debut at the Monaco Yacht Show.

2. ‘Foners’ | 80.56 mph

Clocking a thrilling 70.10 knots (80.56 mph), the 136-foot Foners has maintained pole position as the world’s fastest superyacht for over 20 years. Powered by two 1,280hp MAN engines coupled to three Rolls-Royce 6,700 hp gas turbines driving three KaMeWa water jets, the all-aluminum boat is less about piercing waves and more about parting the seas. Delivered in 2000 by Spanish shipyard Izar as the King of Spain’s royal yacht, no expense was spared, including a superstructure lined with Aramid fiber for the express purpose of bulletproofing the interior.

3. ‘World Is Not Enough’ | 77.1 mph

You need to only look at the 007-inspired name to know that World Is Not Enough is another rapid racer commissioned by John Staluppi, this time with an opulent interior designed by his wife Jeanette in partnership with Evan K Marshall. Delivered in 2004 by Millennium Super Yachts, the 139-footer is powered by two Paxman diesel engines and two Lycoming gas turbines to produce a staggering 20,600hp and a breathtaking 67 knots (77.1 mph). When not leaving other boats behind, World Is Not Enough has a cruising range of 3800 nautical miles at a comfortable speed of 10 knots.

4. ‘Galeocerdo’ | 74.8 mph

Wally founder Luca Bassani designed the 118-foot Galeocerdo to maintain speed in rough seas. Launched in 2003 by Rodriquez Yachts, the boat racks up an eye-watering 65 knots (74.8 mph), thanks to its three Vericor TF50 gas turbines, each driving a Rolls-Royce KaMeWa water jet. Another performance-enhancing feature is the lightweight titanium exhaust system designed to resist the extreme temperatures generated by the gas turbines. Wind tunnel tested at the Ferrari facility in Maranello, Italy, the boat generates 16,800hp and a 45-knot (51.8-mph) cruising speed that’s faster than most motoryachts running flat out. It also enjoys a highly futuristic exterior design.

5. Tecnomar for Lamborghini 63 | 72.5 mph

When Italian supercar brand Lamborghini teamed up with yachting stalwart The Italian Sea Group, the end result had to be style and performance. The Tecnomar for Lamborghini 63 is all about the power of ‘63’. Designed and built to celebrate the year 1963 when Ferruccio Lamborghini founded his car company, the 63-footer delivers a whiplashing top speed of 63 knots (72.5 mph). And naturally, it’s one of just 63 in the series that will ever be made. Built out of carbon fiber, it’s fitted with two MAN V12-2000HP engines. MMA fighter Conor McGregor took delivery of hull number one in 2020, which reportedly cost $4 million.

6. ‘Chato’ | 71.9 mph

Back in the mid-1980s, passionate Baglietto customer and leading US Porsche and VW dealer Baron John von Neumann, commissioned a new 85-ft. speed demon from the Italian builder. The entrepreneur was tired of his 34-knot (39-mph) Baglietto getting creamed from Monaco to St. Tropez by faster cruisers. With a hull design by the legendary Alcide Sculati, the all-aluminum Chato came with MTU’s latest 3,480hp V16s coupled to KaMeWa waterjets. Weighing 60 tons, and packing almost 7,000 hp, the military-looking superyacht with its battleship-gray paint and bright-red diagonal hull stripes, hit an astonishing top speed of 62.5 knots (71.9 mph) during sea trials. Chato is currently for sale in the South of France for $715,000.

7. ‘Oci Ciornie’ | 69.04 mph

Oci Ciornie’s Vripack-designed interior may take inspiration from aircraft designs, but it’s the boat’s naval architecture by Don Shead and the combination of two 1,800hp MTU 16V 2000 M90 engines, a 4,600 hp AVCO Lycoming gas turbine and Arneson surface drives that put it on this list. Delivered in 1998 by Palmer Johnson with an aluminum hull, the 82-foot boat thrusts through water at 60 knots (69.04 mph), giving all eight guests the waterborne ride of their lives.

8. ‘Destriero’ | 68 mph

The numbers almost defy logic. With a length of 224 feet, the all-aluminum superyacht Destriero is massive. Now add a trio of GE Aviation LM1600 gas turbines totaling an insane 60,000 hp and the incredulity only increases. Flat out, Destriero could scythe through waves at a staggering 59 knots, or 68 mph. Back in 1992, just one year after its launch, the Fincantieri-built rocketship showed its chops by challenging the famous Blue Riband trans-Atlantic speed record. Averaging 53.09 knots for the 3,106 nautical-mile run, Destriero shattered the record, only to be denied the trophy for being classed as a private yacht and not a commercial passenger vessel. Sadly, today the iconic yacht lies largely abandoned at one of Lurssen’s yards in Germany, awaiting rescue.

9. ‘Ermis²’ | 65.59 mph

Some yachts feature slippery hull designs, others are propelled by rockets, but the McMullen & Wing-built Ermis² is one of the fastest yachts on the superyacht circuit thanks to its lightweight materials. Built from a combination of carbon/epoxy, aerospace grade carbon fiber and titanium, the 123-foot boat taps out at 57 knots (65.59 mph.) Delivered in 2007, its 10,944 horsepower comes from three MTU 16V 4000 M90 engines. Designed inside and out by Rob Humphreys, its classic looks disguise the speed demon within.

10. ‘Why Not U’ | 63.3 mph

Why Not U is a yacht that comfortably cruises at 47 knots (54.1 mph)—a speed most owners only dream of reaching. When time is of the essence, the boat cranks up its Vericor TF40 gas turbine engines to max out at 55 knots (63.3 mph). Delivered by Overmarine in 2001, Why Not U ’s 4.3-foot draft makes it well suited for cruising shallow waters, while its sunbathing areas allow guests to catch some rays traveling at the speed of light.

11. ‘Alamshar’ | 52 mph

Alamshar is another custom collaboration between Donald Blount and Pininfarina commissioned by Aga Khan IV, this time with interiors by Redman Whiteley Dixon. It was reportedly built for an estimated $200 million at the Devonport shipyard in Falmouth, United Kingdom, and took 13 years to complete. When it was eventually delivered in 2014, Alamshar’s top speed of 45 knots (51.78 mph), generated by twin Rolls-Royce Marine engines and three waterjets, seemed worth the wait.

12. ‘Moon Goddess’ | 51.78 mph

Exterior designed by Espen Øino with an interior by Franco Zuretti, the all-aluminum Moon Goddess is a 115-foot yacht with a turquoise hull that matches the color of its oversized leather sunpads. When cruising at 30 knots (34.52 mph) or tearing up the oceans at 45 knots (51.78 mph), most other boats just catch a glimpse of sea spray that the planing yacht leaves in its wake. It’s powered by twin MTU 16V 4000 M90 diesel engines with twin water jets, which generate a combined 7,498 hp.

13. ‘Azzam’ | 35.7 mph

At a staggering 590 feet bow-to-stern, the Lurssen-built Azzam earns the title of world’s longest privately owned gigayacht. But with its remarkable-for-the-size top speed of 31 knots (35.7 mph), it’s also the fastest. Twin 12,000hp MTU V20 turbo-diesels do the day-to-day powering at up to 18 knots (20.7 mph). But crank up the twin GE LM2500 gas turbines, coupled to four Wartsila waterjets, and there’s a staggering 94,000hp on tap. Of course, like Azzam ‘s original owner, it helps if you own a few oil wells: At max speed, the yacht reportedly burns 13 tons of fuel an hour. Launched in 2013 at a reported cost of some $600 million, Azzam accommodates 30 guests pampered by up to 80 crew.

How Fast Do Boats Go? (20 Boat Types Checked)

Just like cars, there are many factors that go into determining the top speed each boat can go. The shape, engine, hull material and weight all play a significant role in determining the top speed. However, in this article, we will break down all the different boat types and explain how fast you should expect them to be able to go.

Most boats will go about 30-60 mph. Generally, boats such as pontoon boats, cabin cruisers, yachts, and trawlers have a top speed closer to 30 mph or less. Other boat types such as bass boats, ski boats, center consoles, and cuddy cabins will go closer to 60 mph or more.

Other boat types such as sailboats, dingies, and tug boats usually will only reach speeds of 10-20 mph. While jet skis, go-fast boats, and some bass boats can reach speeds of 55-100 mph.

20 different boat types and how fast they go

What are the factors that determine how fast a boat can go?

As you can see, the speed of a boat can be drastically different, even ones of the same type. There are many factors that determine speed, such as engine horsepower, drive type, boat shape, boat weight, trim tabs, weather conditions, and more. However, in this article, we’re going to simplify it to the four that affect the boat the most.

1. Engine Horsepower

The amount of force propelling your boat forward is the number one factor that affects the speed of your boat. The more horsepower you have, the faster your boat will go. However, manufacturers set a limit to how much horsepower you can have depending on each type of boat they make.

This means many boat types are limited to only the speed they can reach with the maximum amount of horsepower allowed (which is usually plenty of speed).

Many times larger boats will put multiple engines in the back of their boat in order to get more power and travel faster, as shown in the image below.

2. Drive/engine type

There are generally three different types of boat engine types. These are outboards, inboards, and stern drives. Generally, outboards are the lightest, so they tend to be able to move a boat slightly faster than the other engine types. However, you can have more horsepower per engine with inboard and sterndrive engines.

The only thing that really affects the speed is the drive type. These consist of a jet drive, I/O, straight shaft, and V-drives.

Generally, jet drives lose the most amount of horsepower when transferring power from the engine to the jet. This means that a propeller-powered boat with a 200-horsepower engine may need to have a 250-300 horsepower engine to go the same speed at full throttle if it were jet drive.

Stern drives come in second when it comes to power loss. They lose about 10%-15% of the engine horsepower when converting it into the propeller. This is because they have to redirect power twice.

V-drive next, they lose about 6%-15%. This is because of the extra joint they need in order to transfer the drive shaft to the correct position. This causes them to have to redirect power at almost a 180-degree angle.

Straight shaft drives are the most efficient at turning engine horsepower into power for the propeller (this means they are the fastest considering engines with the same horsepower). This is because there are no areas where there needs to be power redirected. The drivetrain goes directly from the engine to the propeller.

3. Boat weight

Obviously, the heavier the boat, the slower it’s going to go with the same engine. So many manufacturers try to make their boats as light as possible, especially if they’re building a boat for speed, such as go-fast catamarans.

Aluminum boats weigh less than fiberglass boats, which means aluminum boats of the same size and same engine will generally go faster than fiberglass boats. However, most aluminum boats have an engine horsepower limit that is much lower than fiberglass boats, meaning they generally end up only being able to go the same speed due to power limits.

4. Boat shape

The design and shape of a boat play a big part in how fast it can go. The more surface area in the water, the more drag a boat will have against the water and the slower it will go. This is why many boats designed for speed will be designed to be very narrow or with catamarans such as the image below:

Meanwhile, boats that don’t care for speed and instead opt for more cargo or living space tend to have much wider hulls and lower drafts. Here is an example of such:

Boat speed calculator

If you know the weight, horsepower, and type of boat, you can get a good estimate of how fast it can go. You can do this by using this boat speed calculator from omnicalculator.com.

They make it really easy to just put in the information, and it will give you an estimate that should be very close to the speed your boat will be able to reach.

For example, I put in the information for my Sea-Doo Fish Pro Scout jet ski, which goes about 52-55 mph at full throttle. The calculator predicted, 57.01 mph, which still could have been my fault as its hard to predict the exact wet weight of the jet ski. You can see this in the image below:

Does speed feel faster when you’re on a boat compared to a vehicle on land?

The quick answer to this is, absolutely it does. When you’re on a boat, your open to the wind and water blistering past you as you pick up speed. This makes everything seem faster than on land. Even if you’re in an enclosed boat, the feel of cutting through water and bouncing to waves makes you feel more vulnerable when compared to being in a car, which means you feel as if you are going faster.

One thing to note is that the smaller your boat is, the faster you will feel like you are going. Going 40 mph in a big enclosed cabin cruiser may seem faster than in a car, but it doesn’t even compare to the feeling of going 40 mph on a jet ski.

The fact that some jet skis can reach 70 mph is absolutely astonishing. On my Sea-Doo jet ski, it’s hard to go any faster than 40 mph because I feel one bad wave will bump me off the thing if I go any faster. I couldn’t even imagine 70 mph.

Why would you need speed for a boat?

Although it’s fun and all to go fast on the water, for most of us, it’s really not necessary. Generally, it’s going to cost more for boats that go faster, when you could easily get a similar boat that goes a little slower for much cheaper. That being said, here are the main reasons you would want a boat that is fast:

• You fish in tournaments and need to get to fishing spots as quickly as possible
• You want to partake in a poker run
• You need to travel long distances every time you take your boat out
• You just enjoy going fast

Although many people max out the horsepower they are allowed to put on their boat (some even add more than what they are allowed to) to make it as fast as possible, is that really worth it to you? Believe me, 50 mph is plenty of speed for any boat type as long as you don’t absolutely need to go any faster than that.

What Are The Fastest Sailboats? (Complete List)

Last Updated by

Daniel Wade

August 30, 2022

Whenever you are looking into buying a sailboat, they often tell you how fast it can go. So naturally, customers want to know, what are the fastest sailboats?

Depending on the model and brand of a sailboat, in addition to the right conditions out on the water, this answer can vary. But which sailboats are known to be the fastest?

Each style of sailboat has its advantages that make it fast. The V.O 60, X-Yachts X4.0, and Beneteau Oceanis 30.1 are great examples of fast monohull boats. For multihull boats, Rapido 60 (Trimaran), Dragonfly 40 (Trimaran), and ICE Cat 61 (Catamaran) are some of the fastest in that category.

The list can go on when you are talking about specialized performance boats, foiling boats, and even windsurfers. However, the most common sailboats that people can relate to are either monohulls or multihulls.

According to sailing experts, fast can mean 12 knots if you are only used to going about half that speed. But when you speak about the fastest sailboats, they usually top around 30 knots or more out on the water.

‍ What Makes a Sailboat Fast?

A lot of variables come into play to help a sailboat reach its maximum potential for going fast. While the person running the boat is the one responsible for making it go fast, the weather conditions and type of boat have to be good in order to reach top speeds.

If a boat is not designed to handle rougher conditions, you will struggle with performance in those situations. If you have a boat that is built for anything nature throws at it, you might have better stability but considerably less speed even in good conditions.

Weight and Power of Boat

If you were to have two objects with different weights and put the same amount of force on them, the lighter object moves faster. This is why lighter boats move quicker than heavier boats.

So if you were to put two boats at one end of a race head to head with the same conditions of wind and sailing area, the lighter boat wins. This is because the lighter boat is able to gain speed quickly due to the less weight it holds.

The weight of the hull is only one part of the equation, as the mast can hold a lot of weight too. If there is a way to reduce the weight on the boat, you will have a better chance at going faster.

This is why fast boats typically are made out of materials such as carbon fiber or fiberglass. If the boat is a multi-hull without a keel, this also cuts down on weight.

Friction and Wetted Surface

Water adds a ton of friction to the boat, so a fast boat needs to be able to cut through it efficiently. In addition, some boats have finely polished exteriors to help glide through the water and reduce drag.

Depending on the shape of the hull and how much wetter surface it has can greatly affect the amount of drag it has. For example, displacement hulls change as the boat heels in the water.

For multihulls, these lift the hull out of the water slightly to reduce drag. Hydrofoils are another example that lifts the entire boat out of the water to greatly reduce the wetted surface.

Sail Area and Wind

The bigger the sails are on a boat does not necessarily mean the boat will be the fastest. While the sailing area is critical for speed, it has to match the sailing area to displacement ratio.

The sail area needs to be more about the lift of the sails rather than the size of them. If the proper sails are there, then the boat should be able to reach its maximum potential if the wind conditions are right.

Fastest Sailboat Types

The type of sailboat makes a big difference in speed since it has different characteristics. These include HP monohulls, catamarans, and trimarans.

Each boat type will have a unique position in the water, making it potentially faster than another type. If you want to compare boats in perfect conditions, you can see how one stacks up to another.

HP Monohulls

HP monohulls gain a lot of their speed by being powered by a motor. While they have the capability to sail using the wind, they have the convenience of a motor to help push them along.

So the outboard motor needs to be able to handle the weight of the boat efficiently in order to help reach top speeds. A lot of larger boats need to be pushed along by multiple motors.

Monohulls in general are favored by many sailors since they have that traditional look to them. They also happen to be very common, but multi-hulls are making things competitive in the market.

Catamarans do not have a keel and it helps reduce the weight of the boat. They also displace less water compared to a monohull. However, not all catamarans go fast.

Depending on the catamaran and its capabilities, there is some that glide effortlessly on the water. These ideally work best in good conditions but will be a bumpy ride if the water is a little choppy.

They offer one of the safest rides on the water and are essentially unsinkable due to their design. They spread out their weight over a larger area on the water, making them more stable than a monohull.

In addition, the living space on a monohull is huge compared to a monohull. With about a 40-foot catamaran, it has around the same living space as a 60-foot monohull.

Trimarans are another unique style of sailboat similar to a catamaran. They have three hulls side by side instead of two, making it very stable.

They also have a wide sail area and make for quick spurts out on the water. However, they also need good conditions to operate their best to move fast.

These displace water similar to a catamaran and are more stable. They also tend to go faster in the right conditions than a catamaran.

Both catamarans and trimarans generally have shallow drafts and can be beached. In coastal waters, monohulls have to watch out for their draft since they have a keel.

Fastest Monohull Sailboats

Some of the fastest monohull sailboats have unique characteristics that set it apart from other monohulls. These include sail area, weight, and wetted surface.

The beauty about monohulls is the keel, which has its advantages in tougher conditions. If you were to race a monohull against a multihull in moderate conditions, the monohull has a better chance at navigating through the water due to the keel and potentially going faster. The keel allows the boat to heel from one side to the other and come back to the center.

The Volvo Ocean 60 is one of the fastest monohull sailboats you can find. It is a perfect example of an offshore sailboat that is usually handled by four professional sailors and eight mates on deck.

This boat is roughly 64 feet long and sits about 12 feet in the water. The fastest that these boats go ranges around 35 to 40 knots, but it takes the right conditions and a little bit of patience for that large of a boat.

2. X-Yachts X4.0

The X4.0 yacht was a winner of the European Yacht of the Year award in 2020. It is a fairly new boat design, as it debuted in 2019.

This 40 foot luxury yacht is a top-of-the-line performance cruiser that is built for speed and is lightweight. Sitting about eight feet in the water, this boat can reach up to 10 knots or potentially more with the right conditions. You can quickly reach these speeds due to its size and weight.

3. Beneteau Oceanis 30.1

The Beneteau Oceanis 30.1 is another great example of a power cruising yacht that is new to the scene in 2019. At around 31 feet, it is one of the smaller yachts on the list but packs a powerful punch in performance and speed.

The max draft of this one is just shy of 6.5 feet and it received the Best Performance Cruiser in 2020. While this one, in particular, is built more for luxury and comfort, you can easily see top speeds ranging from 7.5 to 10 knots.

4. Santa Cruz 52

The Santa Cruz 52 is a perfect combination of a lightweight sloop and a blue water racer. At 53 feet long and a draft of nine feet, this boat is a beauty to see go fast.

These are often compared to the original Swan sailboats around the same length, as far as the class and style of the boat. In good conditions, they top around eight knots on a good day.

The Amel 60 is another beauty of a luxury yacht cruiser spanning almost 60 feet in length and nearly an eight-foot draft. This boat began production in 2019 and received the 2020 European Yacht of the Year Luxury Cruiser award.

With a reliance on the engine, you can push the boat a little harder in good conditions to gain more speed. While topping out the engine, you are looking at anywhere between eight and 10 knots.

Fastest Multihull Sailboats

Multihull sailboats are generally faster than monohull sailboats due to their lack of extra weight. These are up to 30 percent faster in that situation.

The only downside is that if you want to reach those maximum speeds, you cannot add a lot of extra weight to the vessel. So for sailors that want to utilize a multihull’s full potential, they need to consider what they bring on board and how many people they have.

1. Rapido 60 (Trimaran)

The Rapido 60 is one of the fastest multihulls out there for its size. At nearly 60 feet in length and almost 11 feet in draft, this unsinkable trimaran can speed up to 25 knots.

These were first built in 2015 and are a popular trimaran to look at if you are wanting the space. In the right conditions, the manufacturer says you can easily reach 30 knots if not more.

2. Dragonfly 40 (Trimaran)

The Dragonfly 40 is one of the few 40-footers out there that you can operate shorthanded. While it typically accommodates six to eight people, the boat’s design allows it to be easily handled.

According to the manufacturer, they claim it can reach 24 knots. Assuming the conditions are perfect, it could potentially reach more.

3. ICE Cat 61 (Catamaran)

The ICE Cat 61 is just a tad over 61 feet long and is one of the more beautiful catamarans you will ever see. For its size and design, it is impressive to see it reach top speeds.

With just the motors alone, you can easily reach 13.5 knots. If all the right conditions are in play, you can expect to reach up to 25 knots.

4. SIG45 (Catamaran)

The SIG 45 is a 45-foot racing cruiser that can comfortably hold about six people. With features like low dragging bows, carbon fiber material found in spars and bulkheads, and around 1,400 square feet of sailing area to play with, you can expect top performance all the way around.

It is estimated that this boat can safely top out around 20 knots. However, there is room for more knots in the best conditions.

5. Lagoon 67 S (Catamaran)

The Lagoon 67S is one of the rarest catamarans you will ever see. There were only four built from 1993 to 1995 by Jeanneau Technologies Avancées and are a gorgeous sight to see.

Regardless of the age of this boat, it still flies in the right conditions like the newer catamarans you see today. You can expect to reach a little over 20 knots for this 67 footer and about five feet of draft.

Speed boats, with their sleek design and powerful engines, evoke a sense of exhilaration and adventure on the water. From racing boats to luxury cruisers, these watercraft come in various shapes and sizes, each engineered for specific performance levels. If you’ve ever wondered just how fast speed boats can go and what factors influence their speed, you’re in for an enlightening ride.

In this comprehensive guide, we will delve into the world of speed boating to uncover the secrets behind their impressive velocities. Whether you’re a speed enthusiast or simply curious about these high-performance vessels, join us as we explore the factors that determine the speed of speed boats and unveil the thrill of chasing the horizon on the open water.

Various Types of Speed Boats Available in the Market

Speed boats encompass a diverse range of watercraft, each crafted with distinct designs and propulsion systems to achieve specific speed goals. Let’s explore the different types of speed boats available in the market:

• Powerboats: Powerboats are the most common type of speed boats and come in various styles, such as bowriders, center consoles, and cuddy cabins. They are propelled by internal combustion engines, typically using gasoline or diesel fuel. Powerboats are versatile and well-suited for recreational activities like waterskiing, wakeboarding, and leisure cruising.
• Jet Boats: Jet boats utilize waterjet propulsion instead of traditional propellers. Water is drawn through an intake and expelled at high speed through a nozzle, propelling the boat forward. This design allows jet boats to operate in shallower waters and provides increased maneuverability, making them popular for river and shallow water use.
• Hydroplanes: Hydroplanes are specialized racing boats designed for high-speed competitions. They have a distinct hull shape, often featuring a stepped design to reduce drag and improve stability. Hydroplanes can achieve astonishing speeds and are commonly used in events like hydroplane racing and drag boat racing.
• High-Performance Boats: High-performance boats are custom-built vessels designed for maximum speed and agility. They often have powerful engines, lightweight construction, and advanced hull designs to minimize drag and enhance performance. These boats are favored by thrill-seekers and racing enthusiasts for their exceptional speed capabilities.

Each type of speed boat is engineered to cater to different water conditions and boating preferences. Whether you seek the thrill of racing, the versatility of recreational activities, or the agility to navigate shallow waters, there’s a speed boat designed to meet your needs and ignite your passion for high-speed adventures on the water.

Key Factors That Influence the Speed of a Boat

The speed of a boat is influenced by a combination of factors that work in unison to determine its maximum velocity. Understanding these key factors can shed light on the thrilling world of high-speed boating:

• Engine Power: The engine’s horsepower and torque play a pivotal role in a boat’s speed. A more powerful engine can generate greater thrust, propelling the boat forward with more force. High-performance boats often boast powerful engines to achieve remarkable speeds.
• Boat Weight: The weight of the boat, including passengers, fuel, and equipment, affects its buoyancy and overall performance. A lighter boat experiences less resistance and can reach higher speeds with greater ease. Manufacturers often use lightweight materials to enhance a speed boat’s performance.

Serial boat owner and adrenaline junkie Elliott Maurice picks out 6 of the fastest boats available on the market…

A rarefied segment of the boating industry is dedicated to creating some of the fastest boats in the world. They’re the Bugatti Chirons and Koenigseggs of the seas. Builders of these boats work to extreme tolerances, using exotic materials and construction methods usually found in the aviation industry.

Of course, at this level, low volume production and the aforementioned construction methods combine to create an exclusive product with an even more exclusive price tag. These super high-performance boats will be hugely impractical for most purposes, when compared to a typical leisure vessel, and the skipper will need significant ability to get the most out of it.

In reality any boat capable of speeds more than 60 knots (69mph) is very fast indeed. Given the hugely changeable nature of water compared to tarmac, this is akin to driving a car at around 120mph.

Most of the fastest boats use race-derived hulls with roots dating back to the 1980s when the ‘Go-Fast boat’ became synonymous with the glamor and excesses of the time. TV shows like Miami Vice , with Don Johnson catching drug dealers in his iconic Wellcraft 39 Scarab , helped make these boats extremely popular.

In reality, high performance offshore boats of this type were extensively used by cartels to run drugs into Miami, with the DEA commissioning a fleet of Blue Thunder powercats to help combat the problem.

Fast forward to today, some of the fastest boats are capable of exceeding 180mph with specialist engines and are in fact faster than the boats in Class 1 Offshore racing, where horsepower is limited to twin 1,100hp.

This list is by no means exhaustive – there are also a number of phenomenal offerings out there from legendary builders like Nortech, Sunsation, Donzi and Fountain.

It’s important to understand these factors as they play a crucial role in determining how fast your boat can go. So, grab your captain’s hat, and let’s set sail into the world of boat speed!

Hull Design

The design of the boat’s hull has a significant impact on its speed and performance. Different hull shapes are optimized for specific purposes: speed, stability, or fuel efficiency. Two primary hull types are commonly found in boats: planing hulls and displacement hulls.

Planing Hulls: These hulls are designed to rise and glide on top of the water when enough power is applied. With a flatter or V-shaped bottom, planing hulls create lift and reduce water resistance, allowing the boat to achieve higher speeds. They are commonly found in speedboats, powerboats, and some pontoons designed for increased velocity.

Displacement Hulls: Displacement hulls are typically found in sailboats and trawlers. These hulls are designed to displace water as the boat moves through it, creating a wave system. Displacement hulls have a lower maximum speed compared to planing hulls but excel in providing stability and fuel efficiency, making them ideal for long-distance cruising.

Engine Performance

The power of the boat’s engine plays a crucial role in determining its speed capabilities. Factors such as horsepower, torque, and fuel efficiency all contribute to the overall performance.

Horsepower (HP): The horsepower rating of an engine indicates its power output. Generally, higher horsepower translates to higher speeds. As the engine generates more power, it propels the boat forward with greater force, enabling it to reach faster speeds.

Torque: Torque is the rotational force produced by the engine. It determines how quickly the engine can accelerate the boat and maintain speed. Higher torque allows for quicker acceleration, which can contribute to achieving higher top speeds.

Fuel Efficiency: While fuel efficiency does not directly impact a boat’s top speed, it can indirectly affect the distance and duration of high-speed operation. Optimal fuel efficiency ensures that your boat can maintain its speed for a more extended period, making it essential for long journeys or fuel-conscious boaters.

Weight Distribution

The distribution of weight on a boat can significantly impact its speed and performance. Proper weight distribution helps maintain balance and stability, allowing the boat to operate more efficiently.

Overloading a boat with excessive weight can increase resistance and drag, slowing it down. It’s important to stay within the recommended weight limits provided by the manufacturer to ensure optimal performance.

Additionally, the placement of weight on the boat, such as the distribution of passengers and cargo, can affect its trim, or how it sits in the water. Proper trim adjustment allows the boat to slice through the water more smoothly, reducing drag and increasing speed.

Environmental Conditions

The environment in which you’re boating can have a significant impact on your boat’s speed. Factors such as wind, waves, and currents can work with or against you, influencing your vessel’s performance.

Wind: A strong tailwind can provide an extra boost to your boat’s speed, while a headwind can create resistance, slowing you down. Pay attention to wind direction and speed when planning your boating activities.

Waves: Larger waves can cause increased resistance and impact the boat’s ability to maintain speed. In rougher conditions, it may be necessary to reduce speed for safety and comfort.

Currents: Strong currents can either assist or hinder your boat’s speed, depending on whether they are with or against your desired direction of travel. Understanding tidal patterns and current flows can help you plan your routes more effectively.

Remember that these factors interact with one another, and achieving optimal speed involves finding the right balance among them. Factors such as boat design, engine power, weight distribution, and environmental conditions should all be considered to maximize your boat’s performance on the water.

By understanding the relationship between speed and fuel efficiency, and implementing a few practical tips, you can make your boating adventures more cost-effective and eco-friendly.

Fuel consumption increases exponentially with higher speeds. In a motorboat, the faster you go, the more fuel your boat consumes. It’s important to strike a balance between speed and fuel efficiency to get the most out of your fuel tank. 

Here are some tips to help you achieve optimal performance while saving on fuel costs:

Find the Sweet Spot

Every boat has a speed range where it achieves the best fuel efficiency, known as the “sweet spot.” This is the speed at which the boat performs optimally while consuming the least amount of fuel. But how do you find it? Experiment with different speeds and monitor your fuel consumption. Take note of the speed at which your boat seems to operate most efficiently and try to maintain it whenever possible.

Monitor and Adjust RPM

The revolutions per minute (RPM) of your engine can significantly impact fuel consumption. Running your engine at excessively high RPMs can result in excessive fuel burn. Consult your boat’s manual to determine the recommended RPM range for optimal fuel efficiency. Adjust your throttle accordingly to maintain a steady speed within that range.

Streamline Your Boat

Reducing drag and optimizing your boat’s aerodynamics can enhance fuel efficiency. Keep your hull clean and free from marine growth, which can increase drag and hinder performance. Minimize unnecessary weight and clutter on board, as excess weight can slow your boat down and increase fuel consumption. Consider removing unnecessary accessories or equipment when not in use.

Trim for Efficiency

Proper trim adjustment can improve fuel efficiency. Experiment with different trim settings to find the position that minimizes resistance and drag. Adjusting the trim can help your boat glide through the water more efficiently, reducing fuel consumption. Monitor your boat’s performance and trim position, making adjustments as needed to find the optimal balance between speed and fuel efficiency.

Plan Efficient Routes

Efficient route planning can make a significant difference in fuel consumption. Consider the impact of wind, currents, and waves on your journey. Opt for routes that take advantage of favorable conditions, such as tailwinds or calmer waters. Minimizing the effects of opposing currents or strong headwinds can reduce the need for excessive engine power, ultimately saving fuel.

Practice Smooth Acceleration

Avoid sudden bursts of acceleration when starting or increasing speed. Smooth and gradual acceleration is more fuel-efficient. It allows the boat to reach desired speeds without putting unnecessary strain on the engine, reducing fuel consumption.

Regular Maintenance

Proper boat maintenance is vital for optimal fuel efficiency. Regularly service your engine, change filters as recommended, and ensure that your boat’s systems are in good working order. A well-maintained engine operates more efficiently, reducing fuel consumption and maximizing performance.

By implementing these tips, you can strike a balance between speed and fuel efficiency, saving money while enjoying your time on the water.

Discover the thrilling speeds boats can achieve, from leisurely cruises to record-breaking dashes across the water.

KEY TAKEAWAYS

• The world record speed for a boat is 275.97 knots (317.58 mph or 511.09 km/h), held by Ken Warby since 1978.
• Boat speeds vary by type, with maximum speeds ranging from 10 mph for houseboats to 114 mph for pontoon boats.
• Safety and stability become concerns at high speeds, with design and engine power being key factors.
• The average speed of a boat is often its most efficient and safe operating speed.
• For recreational boating, speeds around 30 knots are considered fast but safe for certain boat types.

What is the maximum speed of a boat?

This question intrigues many in the marine industry. The fastest boat, according to the Guinness Book of Records, reached 275.97 knots (317.58 mph or 511.09 km/h), a record set by Ken Warby of Australia in 1978. Since then, only two official attempts to break this record have been made, both ending in tragedy due to instability at high speeds.

Boating is often associated with leisure, yet for some, speed is the ultimate goal. Boats, like cars and planes, can reach impressive speeds. The speed of a boat depends on its size, type, engine power, and design.

For example, cargo ships can travel at 24 knots (44 km/h) , while the fastest passenger catamaran recorded a speed of 58.2 knots. A typical pontoon can reach 36 knots (41 mph or 65 km/h), but the world’s fastest pontoon boat hit 99 knots (114 mph), powered by three Mercury Pro Max 300x engines.

Maximum Boat Speed For Typical Boat Types

How Do You Calculate The Average Speed Of A Boat ?

Calculating the average speed of a boat involves understanding its typical operational speed range, rather than aiming for maximum records. Boats are designed with optimal speed considerations, balancing the thrill of speed with safety. The average speed, such as 22 mph for pontoons, reflects a boat’s usual operational pace.

To determine this average speed, several methods can be employed:

• Crouch’s Planning Speed Formula : This approach provides insights into hull speed, which is the maximum speed before the boat’s movement becomes inefficient due to wave resistance. It’s a theoretical limit, not an absolute cap, indicating when additional power results in diminishing speed returns.
• GPS Measurement : A straightforward and accurate method, using GPS to track and calculate the boat’s speed over time.
• Doppler Effect (Doppler Shift) and Correlation Velocity Log : These technologies measure the boat’s speed by analyzing changes in frequency or motion relative to water, offering a precise average speed calculation.

The average speed is essentially the mean of the boat’s most common operational speeds. For instance, if a boat frequently cruises between 18 and 24 mph, its average speed is calculated as (18+24)/2 = 21 mph. This figure represents a practical speed that balances performance with safety and efficiency.

Is 30 Knots Fast For A Boat?

Yes, 30 knots is considered fast for many types of boats, offering a thrilling experience while maintaining safety and efficiency under the right conditions.

Speed is a relative concept in boating, with 30 knots (approximately 34.5 mph or 55.5 km/h) representing a significant pace on the water. This speed is achievable and can be sustained safely by boats designed for swift movement, such as deck boats, pontoons, center console boats, and runabouts. These vessels can maintain 30 knots without compromising their stability or operational efficiency, making it an ideal speed for those seeking excitement on the water.

Conversely, for certain types of boats like tugboats, dinghies, trawlers, sailboats, and ski boats, 30 knots exceeds the recommended speed, posing safety risks and becoming economically inefficient due to increased fuel consumption. For larger vessels such as yachts and ferries, while 30 knots is within a safe operating speed, the fuel costs associated with maintaining this speed make it an impractical choice for regular operation.

What Happens If The Speed Is Too High?

For those who enjoy the pleasures of boating, it’s well-known that boats may feel unstable at rest. Typically boats gain stability as they pick up speed. However, this stability can be compromised when speeds become excessively high.

At rest, a boat’s stability is influenced by various factors, including its displacement mass, the free surface effect, metacentric height , and the conditions of the sea. These factors contribute to the boat’s ability to remain upright and balanced in water.

As a boat accelerates, its hydrostatic and hydrodynamic characteristics evolve, altering the center of buoyancy, underwater volume, and pressure distribution. Initially, as speed increases, so does the boat’s restoring force, which helps maintain stability. Yet, there’s a threshold beyond which further acceleration leads to a decrease in this restoring force, making the boat increasingly unstable.

This instability is exacerbated by changes in the boat’s damping coefficients, both linear and nonlinear, which play critical roles in how a boat responds to rolling motions. As speed continues to rise, these changes can significantly impair the vessel’s stability, posing safety risks.

In summary, while moderate speeds can enhance a boat’s stability, pushing beyond certain limits introduces a risk of instability. Understanding and respecting these limits is crucial for safe boating practices.

How Fast Will A 200 HP Pontoon Go?

Pontoons, often associated with leisurely water activities, can surprisingly accommodate a range of water sports, from wakeboarding and tubing to water skiing. A 26-foot pontoon equipped with a 200 horsepower (HP) engine can achieve speeds up to 40 mph, demonstrating its capability beyond just leisure cruising. Even when loaded to capacity, such a pontoon can maintain a respectable speed of 30 mph, fitting well within the ideal speed range of 15 to 35 mph for various water sports.

While it may not be the fastest option on the water, a pontoon with this power level is more than adequate for engaging in your favorite water-based activities. It’s important to note, however, that the boat’s speed can be influenced by its load. Research indicates that for every additional 1000 pounds, the speed of a pontoon can decrease by approximately 12-15%.

For those considering an upgrade for more speed, remember that simply increasing the engine’s horsepower isn’t the only factor. According to a general guideline, doubling the boat’s speed may require quadrupling its power, although this is more of an estimation than a precise formula.

Enhancing a pontoon’s speed can also involve structural modifications, such as adding an extra pontoon to create a tritoon. This adjustment can improve the boat’s stability and potentially its speed, offering a practical approach to achieving a faster, more enjoyable ride on the water.

Boat speeds vary widely across different types, with the thrill of speed balanced against the need for safety and stability. Whether cruising leisurely or pushing the limits, understanding a boat’s capabilities and limits is essential for a safe and enjoyable experience on the water.

Frequently Asked Questions

Can a boat go 100 mph.

It has been recorded that most modern-day speed boats can travel at speeds of 100 mph with some speed boats even recording speeds of more than 170 mph.

How Far Can You Travel On A Yacht?

Usually, a motorized yacht that is 35 feet in length can travel around 200 miles at a speed of 25 knots in an 8-hour day. If you increase the speed to 35 knots, they can travel close to 300 miles in a day. If you have enough fuel and fill up enough, you can go for thousands of miles.

Go-Fast Boats: Beginner's Guide to the World of Speed

Speed on the water is a rush like no other, and if by chance it captures your imagination you’ll likely spend the rest of your powerboating days chasing it. Not everyone who enters the boating world discovers his or her inner speed gene. But for those who do, it quickly becomes a passion—and likely a lifelong one. 

But assuming you end up on the “love” side of the equation, there are more than a few things that you, as a novice getting into go-fast boating, need to know. What follows is a quick, though by no means comprehensive, question-and-answer guide. It won’t provide everything you need to know, for the education of a powerboat owner, especially in the high-performance realm, never stops. But it will help you understand some of the basics.

Different Types of Go-Fast Boats

Go-fast boats essentially break into two hull categories: 

• V-bottom (mono hull)
• Catamaran (twin smaller “sponson” hulls with a “tunnel” between them)

Picture “one of those Cigarette boats” and you have a classic V-bottom. Though most are powered by inboard stern-drive engines, a few are offered with outboard-engine power. Their lengths range from 20 to more than 50 feet. Most often, they have single or dual engines. They range from bare bones, meaning a steering wheel, a throttle and two gauges (speedometer and tachometer), to plush with multiple GPS units, front and rear video cameras, FLIR systems, monster stereos, plus cabins and more.

Sticking with the Cigarette mental image, a traditional V-bottom sportboat has a closed deck and a cockpit behind it. Today’s fastest V-bottom sportboats top out at more than 150 MPH.

Center Consoles

More popular these days, however, are V-bottom-based “center consoles” with open-cockpit layouts with bolster seats and lounges from bow to stern and tiny-to-generous cabins inside the consoles. Most high-performance center-consoles are powered by two to four outboards. Top speeds range from 60 to 85 MPH.

Go-Fast Catamarans

Today’s most popular go-fast catamarans range from 28 to 52 feet. Powered by twin inboard engines up to 1,750-HP, they can reach 180 MPH and beyond. Once again, it goes without saying—but still needs to be said—that boats in this rather extreme category take years of experience to learn to handle safely.

A sport catamaran, meaning outboard-engine-powered cats from 28 to 38 feet long, are the hottest things in the go-fast boat segment these days. Equipped with twin outboard racing-style engines, the fastest top out at 130 MPH. Thanks to the outstanding reliability built into today’s outboards and overall ease of use as compared to their larger, higher-maintenance stern-drive counterparts, sport cat popularity has exploded in the last five years.

How Much Does a Go-Fast Boat Cost?

If you’re looking at an entry level new go-fast powerboat, you can expect to spend no less than $100,000. That might seem like a lot of money and, in fact, it is, but it’s not out of line with the pricing in rest of the powerboat world (more than a few ski/wake tow boats list for 50 percent more than that).

Of course, you spend far less than $100,000 in the pre-owned go-fast boat market. On the flip side, you can spend more than $1 million on a new custom creation.

Other Related Costs

Being new to go-fast boating and excited about the world you’re about to enter, this you forget to ask this question. But it’s an important one, so we’re asking it for you.

Short answer: Yes.

Longer answer: Like all forms of powerboating, the high-performance segments includes costs beyond the boat, the most obvious one being fuel. High-horsepower marine engines demand fuel, often higher octane and hence more-expensive fuel, to make power. And they tend to burn a lot of it. By automotive standards, five miles per gallon is appalling. But powerboating—all powerboating—it’s world-beating, even for outboard engines.

Other costs include insurance, which is higher for go-fast boats than it is for boats in other segments. The faster the boat, the more expensive and expensive and difficult it is to insure. Though high-performance marine engines, especially Mercury Racing’s inboard and outboard offerings, have become far more reliable than they once were, they still require more routine maintenance than the lower output engines found in general-use powerboats.

Costs of Boat Ownership Guide

Go-Fast Boats: Frequently Asked Questions

How fast can high-performance boats go?

To make things simple, we’ll define any powerboat that exceeds 70 MPH as a high-performance boat. These days, there are plenty of boats that can run more than 120 MPH and several models that—with enough horsepower—can top 180 MPH. It should go without saying, but still needs to be said, that the highest tier of performance boats take years of experience and a careful, methodical progression to learn to handle safely.

How do I get involved in high-performance boating?

If your family owned a powerboat, there’s a good chance that you might end up owning one someday. Lifelong boat owners typically were exposed to the activity as children. To the outsider, the whole “powerboating thing” can seem intimidating, whereas those who grow up around boats have a hard-coded comfort level with all that boating entails.

Your best bet if you think a go-fast boat appeals to you? Get a ride in one. There are more than a few dealers around the country who can make that happen for you. If you like it, you’ll move forward. If not, move on.

Assuming you like it, you’ll need to take more rides—and we mean a lot of them—with dealers and builders. Don’t be afraid to ask hard questions and don’t be afraid to go elsewhere if the folks introducing you to the go-fast boating world can’t answer them.

How do I learn to drive (and safely handle) a go-fast boat?

Volumes could be written about the progression of go-fast powerboat ownership, but the most simple and solid path is to start small and work your way up.

• For a novice , trying to dock a 50-foot, twin-engine V-bottom in a crosswind, much less run it at speed, would be a horrific and potentially dangerous experience.
• For a seasoned go-fast boat owner , it’s routine—but routine that always needs to be approach with respect and caution. More than a few owners of big, multi-engine catamarans started with a 20-foot V-bottom. And it took them years, as it will take you, to progress up the ladder.

So be patient. Your life and the life of every passenger in your boat depends on it. And get instruction , whether it be from the manufacturer such as MTI or Nor-Tech or an outfit like the Tres Martin Performance Driving School. Listen, learn, ask lots of questions—there are no dumb ones—and take it slowly.

Nothing is without risk. Your job, through a slow progression to experience and competent instruction, is to do your best to minimize it. In time, you’ll be going plenty fast. That’s just what happens when the aquatic speed bug bites.

Short Answer

The speed of a boat depends on a variety of factors, such as the size and type of boat, the weight of the boat and its cargo, the type and size of the engine, and the environment and weather conditions.

Generally, boats can travel anywhere from five to fifty knots per hour.

Some boats can travel faster than fifty knots per hour, but these are usually more specialized boats, such as racing boats or speedboats.

Types of Boats

When it comes to the speed of a boat, the type of boat can have a significant effect.

Small, lightweight boats such as dinghies and kayaks are usually powered by oars or small outboard motors, and can reach speeds of up to 10 mph.

Sailboats, on the other hand, are powered by the wind and can travel at speeds of up to 25 mph.

Racing boats, which are usually made of lightweight materials and have powerful engines, can reach speeds of up to 50 mph.

Motorboats, which are the most common type of boat, are powered by gasoline or diesel engines and can reach speeds of up to 60 mph.

Finally, hovercrafts are powered by high-powered fans and can reach speeds of up to 80 mph.

Factors that Affect Boat Speed

When trying to determine the speed of a boat, it is important to consider several factors.

The size and horsepower of the engine, the size and shape of the hull, and the weight of the boat all play a role in determining how fast a boat can go.

The size of the engine is one of the most important factors when determining a boat’s speed.

The larger the engine, the more power it has, which makes the boat faster.

The horsepower of the engine also affects the speed of the boat.

Higher horsepower engines are able to produce more power and, as a result, can reach higher speeds.

The size and shape of the hull also affects the speed of the boat.

A larger, more aerodynamic hull can help reduce drag and allow the boat to reach higher speeds.

On the other hand, a smaller hull can create more drag, which reduces the speed of the boat.

Additionally, the weight of the boat can affect its speed.

A lighter boat will typically have an easier time reaching higher speeds than a heavier boat.

Finally, the type of water the boat is navigating can also affect its speed.

For example, if the boat is in open water, it will typically be able to reach higher speeds than if it was in a river or other confined space.

This is because in open water there is less drag and more space to maneuver.

In addition, the wind and waves can have an effect on the speed of the boat.

Ultimately, the speed of a boat can vary greatly depending on a variety of factors.

The size and horsepower of the engine, the size and shape of the hull, the weight of the boat, and the type of water it is navigating all play a role in determining how fast a boat can go.

Generally, boats can travel anywhere from a few miles per hour to more than 50 miles per hour, with the fastest boats typically being made of lightweight material and having powerful engines.

Maximum Speed of Boats

When it comes to maximum speed, boats come in a variety of shapes, sizes, and speeds.

The most powerful boats can reach speeds of 50 miles per hour or more, but this depends on the engine power, the weight of the boat, and other factors.

The material used to make the boat is also a key factor, as lighter materials tend to travel faster.

For example, a lightweight, high-performance boat made of fiberglass or carbon fiber will be able to reach higher speeds than a boat made of heavier materials.

Additionally, the type of water the boat is navigating also affects its speed.

Open water can provide more power and speed for the boat, while narrow rivers can cause drag and slow the boat down.

The size of the engine is also a major factor that affects the speed of the boat.

Larger, more powerful engines can propel the boat faster, while smaller engines will result in slower speeds.

Some boats are equipped with multiple engines, allowing them to reach even higher speeds.

Finally, the shape of the hull is an important factor that affects the speed of the boat.

Boats with a flat bottom tend to be slower, while boats with a V-shaped hull can reach higher speeds.

Additionally, the size and weight of the boat can also play a role in the speed of the boat.

Heavier boats can travel slower, while lighter boats can travel faster.

In conclusion, the maximum speed of a boat is determined by a variety of factors, such as the size and horsepower of the engine, the size and shape of the hull, and the weight of the boat.

Generally, boats can travel anywhere from a few miles per hour to more than 50 miles per hour.

The fastest boats are typically made of lightweight material and have powerful engines.

The speed of the boat can also be affected by the type of water it is navigating, such as if it is in open water or in a river.

Factors That Impact Maximum Speed

When it comes to the speed of a boat, a variety of different factors can come into play.

The size, shape, and weight of the boat, as well as the horsepower of the engine, can all impact the speed of the vessel.

The size and shape of the hull are two of the most important factors in determining the speed of a boat.

A larger, well-designed hull will be able to push through the water with greater ease, allowing the boat to reach higher speeds.

On the other hand, a smaller and less-aerodynamic hull will create more drag, resulting in slower speeds.

The weight of the boat is also a factor in determining speed.

A heavy boat will require more power to move through the water, which can limit its maximum speed.

Additionally, the weight of the boat will affect the acceleration and deceleration, making it difficult to reach higher speeds.

The horsepower of the engine is also a major factor in determining the speed of a boat.

The more powerful the engine, the faster the boat will be able to reach its top speed.

However, it is important to note that the size and shape of the hull should also be taken into consideration, as an engine that is too powerful for the boat will not be able to reach its optimum speed.

In open water, the boat will be able to reach higher speeds due to fewer obstacles.

On the other hand, navigating a river or other body of water with obstructions can limit the speed of the boat.

By taking into account all of these factors, it is possible to determine the maximum speed of a boat.

Generally, the fastest boats are those that are made of lightweight material and have powerful engines.

The Fastest Boats

When it comes to speed, the fastest boats tend to be the ones with powerful engines and lightweight hulls.

These boats are designed with speed in mind, and they can often reach speeds of up to 50 miles per hour.

The weight of the boat is also a factor, as lighter boats can travel faster.

The type of water the boat is navigating also affects its speed, as open water usually allows the boat to travel faster than if it were in a river.

The fastest boats that can be found on the market today are usually high-powered, motorized boats.

These boats are designed with powerful engines that allow them to reach speeds of up to 50 miles per hour.

The hulls of these boats are often made from lightweight materials, such as aluminum, which helps them reach higher speeds.

Boats with large, powerful engines and lightweight hulls are typically the fastest.

For those looking for the ultimate speed, there are also boats designed specifically for racing.

Racing boats are generally larger than recreational boats, and they are designed with speed in mind.

These boats usually have powerful engines and are designed with a more streamlined shape to reduce drag and improve speed.

Racing boats can reach speeds of up to 100 miles per hour, making them some of the fastest boats available.

While speed is important, it is important to remember that safety should always be a priority when operating a boat.

Boats that are designed for speed should always be operated with caution, and operators should always be aware of their surroundings and the conditions of the water.

Boats should also be equipped with the proper safety equipment and should be operated within the laws and regulations of the area.

Types of Water and Their Impact on Boat Speed

When it comes to boat speed, the type of water a vessel is traveling on can have a big impact.

Boats will typically travel faster in open water than in a river or lake due to less resistance from the current.

In addition, the size of the waves in the open water can affect the speed of the boat.

In choppy waters, boats may experience more resistance and therefore be slower, while in calm waters they may be able to travel faster.

In a river, however, boats may experience more resistance due to the current and depth of the river.

The size of the boat and its engine power will be a factor in how quickly it can travel in a river.

Boats with larger engines and smaller hulls may be able to travel faster in the river.

In addition, the shape of the river can affect the speed of the boat.

If the river has a lot of curves and turns, the boat may slow down because it has to navigate these turns.

In a lake, the speed of the boat will depend on the size of the lake and the size of the boat.

Smaller boats can travel faster on smaller lakes, while larger boats may be limited in how fast they can travel due to the size of the lake.

In addition, the size and shape of the lake can affect the speed of the boat.

If the lake is large and flat, the boat can travel faster, while if the lake is smaller and has more curves, the boat may slow down.

Thus, the type of water a boat is traveling on can have a major impact on its speed.

Boats may travel faster in open water than in a river or lake, but the size and shape of the waterway can also affect the speed of the boat.

It’s important to consider all of these factors when determining how fast a boat can go.

Safety Considerations for Fast Boats

When it comes to operating a fast boat, safety is of the utmost importance.

Regardless of how powerful the engine or how lightweight the boat, there are certain safety considerations that should always be taken into account.

The first is to ensure that the boat is properly equipped with life jackets for everyone on board.

Life jackets should be properly sized and securely fastened to each passenger, and they should be inspected regularly for any signs of wear or damage.

It is also important to make sure that the boat has a working emergency radio and other communication devices in case of an emergency.

In addition, it is important to make sure that the boats lights are in working order and that it is equipped with a navigation system.

This will help the boats operator to avoid any potential hazards.

It is also important to make sure that the boat has the proper safety equipment, such as fire extinguishers, flares, and other items that may be necessary in an emergency situation.

Finally, it is important to remember that fast boats can be dangerous when operated in poor weather conditions, such as high winds or choppy waters.

It is important to be especially cautious in these conditions and to take special precautions to ensure the safety of everyone on board.

By following these safety guidelines, you can ensure that everyone on board has a safe and enjoyable experience on the water.

Final Thoughts

It is clear that boat speed is determined by a variety of factors, and can range from a few miles per hour to more than 50 miles per hour.

The fastest boats are typically made of lightweight materials and have powerful engines.

Additionally, the type of water can have an impact on the speed of a boat.

Therefore, when considering the speed of a boat, it is important to take into account the size and shape of the hull, the power of the engine, the weight of the boat, and the type of water it is navigating.

With this knowledge, you can make an informed decision about which boat is best suited for your needs.

Average Boat Speeds: Pontoon, Cruiser and Sail Speed Examples

How fast do boats go on average?

Is a fast boat the exception or the rule for average boat speeds? 

What horsepower can you realistically expect from the average boat purchase?

Well, these questions can be answered in lots of different ways.

The fastest boat speed record ever was 317.6 MPH. It   was achieved by a man named Ken War who was using a speedboat he named the  Spirit of Australia . To be fair, though, when that boat made its water speed record run back in 1978, it was powered not by a propeller but by a jet engine. Most boats don't go quite that fast (and we're thankful for that). 

Motorboats designed primarily for speed - known as rum-runners in decades past and often called cigarette boats (due to their slender shape) or simply go-fast boats today - can achieve speeds up to 90 MPH with relative ease over calm flat waters.

Even that's quite a bit faster than the average boat speed, and unless you're considering a career in smuggling  (which we don't recommend, by the way), it's probably quite a bit faster than you need to travel over the water.

So, let's talk about average recreational boat speed statistics that are a bit more practical.

Why Boat Speed Matters

Going fast in a boat can be lots of fun.

The enjoyment that comes from speed is a huge plus for adrenaline-seeking boaters. That's one reason why knowing how fast a boat goes is important.

It's also important to consider boat speed when you're getting a boat for water activities. Think about the types of activities for which your ideal boat will be used. You should even consider whether you live in, or want to enjoy your boat in,  high-altitude areas .

Even then, desired speeds can vary. The best speed for a towing activity such as  water skiing  can vary from 10 MPH to 35 MPH. Lower speeds are better for younger skiers and certain trick-skiing activities, and the higher speeds are for more experienced water skiers completing slaloms or jumps. 

As you can see, some action-loving boaters might need a craft with plenty of potential for speed to soar over those saltwater waves .

The fisherman who likes to slowly troll through calm waters or toss out a line and  an anchor, on the other hand, might do well enough with a boat that only cruises along at a top speed of 15 MPH.

If you use your boat for long trips, then balancing speed and fuel efficiency is important.

How you're going to be using your boat should inform the ideal average and top speed ratings of the boat you ultimately buy.

Don't just go looking for a super fast boat that you might not ever really take advantage of. What a waste that would be!

Average Pontoon Boat Speeds

The trusty, stable pontoon boat can travel a good deal faster than many people think.

Pontoon boat speeds  can surpass 30 MPH  under the right conditions. A few pontoon boats can even reach the 35 MPH mark thanks to larger engines and great conditions.

The G3 Suncatcher pontoon boat , with a 90 HP motor, can easily go more than 30 MPH .

A 20-foot Bass Buggy with a 60 HP engine, on the other hand, will only go around 15 MPH .

A middle-of-the-road option in terms of average pontoon boat speed is the 21-foot Triton pontoon boat  and its 90 HP engine. This boat's combination of speed and strength gives it a top boat speed of around 25 MPH even   when you have a few friends aboard weighing it down.

Average Cruiser Speeds

For cruiser-style motorboats that are in the price range of many American families, let's discuss a few options that give a good sense of average powerboat speed.

The Marlow-Pilot 32 has a relatively slow top cruising speed of 16 MPH , but its range at moderate speeds is the more remarkable thing about the vessel. It can travel more than 800 miles without re-fueling.

If you want a motorboat with a bit more speed, such as what a sport fisherman might need, consider the stats of the Pursuit SC 365i Sport Yacht . It can come close to 50 MPH at top speed and cruise comfortably in the 30 MPH range.

Finally, if you're wondering how fast larger motorboats go, the 40-foot Carver C40 Command Bridge cruises along at 30 MPH with ease and is suitable for use during multi-day trips.

Average Sailboat Speeds

Most people use sailboats because they savor the practice of harnessing the wind, not because they expect to go all that fast.

The average cruising sailboat, such as a celebrated Island Packet 420 , will sail along at an average speed of between 8  and 12 MPH  under most decent circumstances.

The world speed record of a sailboat is a bit faster than that, at just over 75 MPH . That breakneck speed was achieved by the  Vestas Sailrocket 2   in 2012.

And just for your interest, have you ever wondered how fast Columbus's ships sailed ? Experts agree that ships of the late 15th century likely cruised along at just under 4 knots and a likely top speed of 8 knots. That's an average boat speed of somewhere between 4 and  9 MPH .

Average Boat Speed and Fuel Consumption

Going fast in a motorboat is lots of fun but it can also be very expensive.

To help get a picture of the direct relationship of average boat speed to fuel used, let's select the Formula 240 Bowrider motorboat as our example. This affordable and capable 24-foot speedboat is a common favorite for American families.

At a steady cruising speed of 7 MPH, the 240 Bowrider consumes about 3 gallons of fuel per hour. At twice that speed, around 15 MPH, it consumes over twice the amount of fuel, burning up around 7 gallons per hour.

Double that speed again and the boat consumes 11 gallons of fuel at around 30 MPH. The Bowrider can go well over 45 MPH.

Many powerboats offer relative fuel efficiency at their mid-range speeds, so puttering along at only a few miles per hour isn't necessary for fuel savings. You can cruise at an enjoyable clip and still conserve fuel.

Laws About Boat Speed

It's generally rather easy to figure out the speed limit when you're driving on a road. All you have to do is look for the posted speed limit sign. Knowing boat speed regulations laws is a bit trickier.

The limits aren't always posted and can change based on a myriad of factors, including the type of waterway, time of day (or night), type of boat and more.

And what's more, a boat speed limit is rarely a specific numerical figure.

Once you're out on the open water of a sea, ocean or large lake, it's safe to assume you can take your boat up to its top speed provided you can see the way ahead of you is safe and clear.

Closer to shore - on a river, in the bay or in other such areas - you have to be a bit more cautious.

Generally, you must watch out for "no wake zones," which are enforced in many places, including near docks and marinas, in canals and near the shore in many cases.

To remain in compliance with a No Wake Zone rule, a boat must travel slow enough that it doesn't produce a swell large enough to threaten others in the area (including other boaters, swimmers, animals and so forth).

Most motorboats produce a noticeable wake at speeds greater than 5 MPH. Yes, navigating the way through a no wake zone can be an exercise in patience. But the rules regarding boat speed were designed to help keep all people out on the water safe, from the family enjoying a trip in their pleasure yacht to the fisherman casting a line off of his sit-on-top kayak.

Keep these considerations in mind when you're choosing your boat and taking it out for a spin to test its full speed.

How Fast Does a Boat Go?

Explore boat speeds across types with our chart! Learn how factors like design & horsepower impact speed, from sailboats at 8 mph to jet boats over 200 mph.

Whether using your boat for transportation or recreation, you need to know how to use it properly. Part of your responsibility is knowing how fast a boat can go so you stay within its limits. The type of boat will influence its speed, but there are average speeds you can consider when looking for a new vessel.

The average speed of a recreational boat is between 10 and 40 miles per hour. Jet-powered boats and racing boats can surpass 200 miles per hour, with the fastest boat on record going 317 mph. A sailboat averages 8 mph, a yacht 50 mph, and a pontoon 22 mph. Many factors influence a boat’s speed.

Depending on your boat’s design and weight, the engine, water temperature and depth, and the wind, boat speed can vary. Understanding the average speed of various boats is a good starting point for finding the right watercraft for you.

What Are the Average Speeds for Different Types of Boats?

You can average 8 miles per hour on a sailboat or reach top speeds of 200+ miles per hour on certain racing boats. Therefore, the type of boat has a significant impact on how fast it will go. But most recreational-style boats go between 10 and 40 miles per hour.

When operating a boat, it's wise to know the average speed as well as the max speed. Of course, regardless of how fast your boat can go, always make sure to abide by any local laws, limits, and restrictions.

Average Speeds of Boats

Here is a glimpse at the average and top speeds of various popular boat categories. Keep in mind that these figures are a rough average since different boat models within each category can have some drastic differences in speed. This difference exists because of things like engine horsepower, hull shape, boat weight, and more.

How Many Miles Per Hour Is One Knot?

One mile per hour is equivalent to 0.869 knots. This conversion is essential to know since many boats will use knots to describe their speed. In some places, boating speed limits might also use knots. 

If you find a boat that claims to reach top speeds of 50 knots, it can go about 57 to 58 miles per hour. If you're near a no-wake zone, you typically can't go more than 5 miles per hour or 4.3 knots.

Is 50 MPH Fast for a Boat?

Smaller boats and those with open helms will feel very fast at 50 miles per hour. But high-speed crafts, larger boats, or closed vessels may feel slow at 50 mph. 

Compared to a sailboat gliding along at 10 mph, 50 can feel super speedy. But you'd likely feel like you're grounded in the slow lane next to a racing boat zipping by at 120 mph. Regardless, 50 mph is still fast when you think about the overall picture.

You're still covering quite a bit of distance in a very short period of time. It's important to keep this in mind to account for your reaction time and any obstacles that might appear in the water. 

Can Boats Go 100 MPH?

There are speed boats that can go 100 mph, high-speed racing boats that go 180 mph, and jet boats that top 200. But 100 miles per hour is fast, so you’d likely go these speeds with racing boats. Recreational boats don’t go this fast.

How Fast Is the Fastest Boat?

Currently, the fastest boat on record is a jet-powered hydroplane called The Spirit of Australia at 317 miles per hour. Ken Warby's boat reached 317.58 miles per hour in 1978 on Blowering Dam Lake in New South Wales. 

However, this was just the official fastest speed. It's actually estimated that the craft reached almost 345 miles per hour almost one year earlier. Warby and his son have since designed and constructed The Spirit of Australia II with the hopes of one day surpassing the record.

How Fast Do Recreational Boats Go?

Recreational boats average between 10 and 40 miles per hour, depending on the style. A sailboat typically has a cruising speed of about 7 to 8 miles per hour. Racing sailboats can reach speeds up to 17 mph.

Smaller fishing boats , like bass boats, can go 30 to 50 miles per hour, while larger trawlers top out at around 23 mph. Ski boats go between 18 and 36 miles per hour.

Most motorboats reach max speeds of 90 to 100 mph. However, you can also find motorboats with powerful engines that can surpass 200 miles per hour.

What Is the Average Fishing Boat Speed?

Fishing boat speeds average about 30 miles per hour, with many going about 7 mph and some reaching 80 mph. It’s hard to pinpoint one average speed for a fishing boat since you can find many types.

The speed of your fishing boat will also depend highly on the power of your motor. Therefore, when shopping for a fishing boat, decide where you will use it most and how. Then you can determine the top speeds you’ll need to reach and how much horsepower you’ll need.

What Factors Can Affect a Boat’s Speed?

A boat’s design and weight, water depth and temperature, the wind, and your boat’s engine all affect the speed. If you want to determine how fast your boat can go, these are the factors you need to consider.

Typically, the longer the boat, the faster it will go. Also, if the hull moves on the water (a planing hull) instead of pushing it away, the boat will go faster.

If instead, your boat has a monohull, it will push more water away as it goes, causing it to move slower. This slower speed is because when the hull has more contact with water, it increases friction. The increased friction is what makes the boat move at a slower speed.

If the hull has a round, flat bottom, it will move at slower speeds. Many boats with this shape hull are pontoons, sailboats, and fishing boats.

However, boats with v-shaped hulls move on top of the water and reach higher speeds. You’ll find this hull shape on many racing boats.

The Boat’s Weight

The heavier the boat, the more friction between the water and the boat’s hull, leading to a slower speed. A boat displaces the water around it, usually as much as the boat weighs. In other words, if your boat weighs 1,500 pounds, it will displace 1,500 pounds of water.

To put it another way, your boat has an extra 1,500 pounds in water it must move as it goes. When you consider it this way, you can see why heavier boats will move at slower speeds.

Water Depth

Your boat will go slower in shallow water because of reduced pressure beneath the vessel. The water under the boat moves faster in shallow water, and your boat will need to work harder to push it away.

Additionally, your boat will need to displace more water to stay afloat. Therefore, this increases the friction, which means slower speeds.

Type of Engine

The more horsepower your engine has, the faster your boat will go. It’s reasonable to consider a more powerful motor will allow your boat to travel at faster speeds.

When you combine the engine power with the boat weight, you can start to get a clearer picture of your boat’s speed. For example, a 5,000-pound boat might go about 25 to 26 mph with a 150-hp engine.

However, that same engine could move a lightweight racer up to 80 miles per hour. An engine with 50 hp might not seem super powerful. But on a lightweight craft, it can move along nicely. However, you might feel like you’re barely moving on a heavier boat.

A 2,000-pound racing boat with a 300-hp engine can go about 81 mph, while a 1,000-pound racer goes 115 mph. Put that same 300-hp engine on a 5,000-pound cruiser, and it will only go about 36 mph.

Temperature of the Water

Boats tend to go faster in warmer water and slower in colder water. Colder water temperatures tend to be denser. 

Denser water consists of thicker water molecules, which increases the friction between the water and the hull. Once again, this increased friction means slower speeds for your boat.

The wind can influence your boat’s speed by making it faster or slower depending on which way it’s blowing. If there is less wind resistance, your boat will move more quickly. Increased wind resistance can slow you down, especially if you are in a sailboat. 

How Do You Calculate Your Boat’s Average Speed?

To calculate your boat’s average speed, you need to know the horsepower, displacement, and Crouch’s constant. Crouch’s constant depends on the type of boat. Most recreational boats have a Crouch constant of 150.

Higher speed boats have a Crouch constant of 190 and racing boats 230. For displacement, use your boat’s weight. (As mentioned before, the amount of water your boat displaces is equal to the boat’s weight.)

Once you have this information, use this formula: 

Speed = sqrt of (horsepower/displacement) X Crouch Constant

Here’s how you can determine the average speed of a 2,200-pound pontoon boat with a 50-hp engine.

Sqrt of (50/2,200) x 150 = 22.61

Of course, if you’re already out on the water, you can simply glance at your boat’s GPS to see what your speed is. You can also get an average speed by considering how fast your boat goes most of the time.

For example, assume most of the time you travel between 20 and 30 miles per hour on your boat. Add these two numbers, divide by two, and you’ll have your average speed. 

20 + 30=50/2=25 mph

What Horsepower Do You Need To Go A Certain Speed In A Boat?

You can determine the necessary horsepower using Crouch’s constant, the desired speed, and boat weight. You use the following formula:

Horsepower = (Speed/Crouch’s Constant) 2 x boat weight

If you want to go 40 miles per hour in a 2,000-pound pontoon, you would do the following.

(40/150) 2 x 2,000 = 142.2

So, in order to reach 40 mph in your 2,000-pound pontoon, you would need a 150-hp engine.

What If Your Boat Goes Too Fast?

If your boat goes too fast, it can become unstable and reckless and also more challenging to stop in time. It's important that you remain in control of your watercraft at all times.

Also, depending on where you are, if you surpass certain speed limits, you could be subject to fines or penalties. For example, speeding through a no-wake or slow-wake zone or near docks and other boaters.

How fast a boat goes depends on its design, weight, and horsepower, as well as the water depth and temperature, and wind. But on average, most recreational watercraft travel between 10 and 40 miles per hour. Racing boats can surpass 200 miles per hour, while cruising sailboats average 8 mph.

To determine your boat’s average speed, all you need to know is the horsepower, boat weight (displacement), and Crouch’s constant. Crouch’s constant depends on the type of boat, but for most recreational vessels, it’s 150.

You can travel 30 to 50 miles per hour on an average bass boat or drift at about 20 mph on a trawler. Do you want to cruise on your pontoon at an average speed of 22 mph or live it up on a yacht going 70 mph? No matter what your speed, you can find lots of fun and relaxation on the waves.

Boat Speed Calculator

Table of contents

The boat speed calculator determines the top speed of a boat based on the boat's power and displacement . If you wonder how fast a boat can go, this calculator will help you answer that. The calculator also utilizes a constant known as Crouch constant which differs based on the type of the boat.

The formula for the top speed of a boat is used by designers to perform preliminary design analysis of the hulls. This helps in keeping the cost of building a boat in check (visit the boat loan calculator for more). Read on to understand how to calculate the speed of your yacht using Crouch's formula and to know how much horsepower do I need for my boat?

What is boat speed — Calculating using Crouch's formula?

The speed of the boat, in simple words, is how fast it can go. However, unlike land vehicles, this speed is not a ratio of distance and time. The speed of a boat having an engine to deliver P horsepower and displacing D pounds is written as:

where S is the boat speed and C is the Crouch constant. The above equation is known as Crouch's formula.

Note: The formulation and value for the Crouch constant are specific for units such as the speed in miles per hour and displacement in pounds.

💡 Our tools can convert units automatically, but if you'd like to learn how to do these conversions yourself, then our speed conversion and torque to hp calculator could come in handy!

What is displacement?

The displacement for a boat is defined as the volume of water displaced . The volume is then converted to weight. This property of a ship is an application of Archimedes' principle . In other words, the displacement of a boat is its weight. This weight is usually measured in tonnes or pounds. For instance, a modern US Navy Gerald R. Ford-class aircraft carrier displaces about 100,000 tons at its full load, whereas a 17th-century fishing boat displaces only about 13 tons. The tonnage of the ship varies as per its class and purpose.

The Crouch constant depends on the type of boat . The constant is applicable to a wide variety of boats, from runabouts to high-speed racing boats. It does not take the hull length into account. The table below has the value of the Crouch constant for different types.

How to calculate boat speed using this calculator?

Follow the steps below to calculate boat speed:

Step 1: Enter the shaft horsepower value, P .

Step 2: Insert the boat's displacement , D .

Step 3: Choose the Crouch constant , C from the list of boat types , or you can directly enter the value.

Step 4: The boat speed calculator will now return the value of boat's top speed.

Example of using the boat speed calculator

Calculate the speed of a racing hydroplane having an engine that delivers 3000 hp and displaces 6800 pounds of water.

To calculate boat speed :

Step 1: Enter shaft horsepower value P = 3000 hp .

Step 2: Insert the boat's displacement , D = 6800 lbs .

Step 3: Choose the Crouch constant , C from the list for hydroplanes, i.e., C = 220 .

Step 4: Using the Crouch's formula: S = √(P / D) × C = √(3000 / 6800) × 220 = 146.13 mph i.e., the speed of the hydroplane is about 146.13 miles per hour.

Alternatively, you can also run this calculator backward to know how much horsepower I need for my boat to achieve a certain speed. Say you want a top speed of 150 miles per hour for your 6,000 lb hydroplane. You can then:

Step 1: Enter top speed value S = 150 mph .

Step 2: Insert the boat's displacement , D = 6000 lbs .

Step 4: The calculator will use Crouch's formula to return the horsepower value as: Power = (P / C)² × D = (150 / 220)² × 6000 = 2789 hp

Therefore, you need an engine to deliver about 2800 hp to take your boat as fast as 150 mph .

How do I calculate a boat's top speed?

To calculate the boat speed:

Divide the power delivered by the boat to the displacement.

Find the square root of the result from step 1.

Multiply by the Crouch constant.

S = √(P / D) × C

What is Crouch's formula?

Crouch's formula is the equation to find the top speed of a boat based on its power P and tonnage D . The speed of the boat, S is given by the equation.

What is the value of Crouch's constant for a racing boat?

A racing boat has the value of Crouch constant around 210 .

What is the value of Crouch's constant for runabout boats?

An average runabout has the value of Crouch constant around 150 whereas it can go up to 190 for high-speed runabouts .

How Fast Can A Boat Go? | Get Answered Now

Last Updated on June 6, 2020 by Amit Abhishek

How fast can a boat go? This is one question everyone has who is anyway related to boats or marine in general. The Guinness Book of Records for the fastest boat is 275.97 knots by Ken Warby in Australia.

When it comes to boating, many think of a leisure sport paddling a kayak, dingy or canoe. While some think of recreational boat party or family time on a pontoon, yacht or a houseboat.

But for a few boating is not something to move at a leisurely pace; rather how fast you can take your boat without accidents. It is for them it matters the most; just how fast can a boat go? especially their own.

When you are asked to think of going fast, people generally think of cars, bikes, airplanes or some times trains. But a boat too can go fast; in fact, the fastest boat record is 275.97 knots or 510km/hr.

The maximum speed of a boat depends on its size, type, engine power ( horsepower ), design consideration and weight.

For example, the maximum speed of cargo ships ( although not a boat ) is 24 knots or 44 km/hr. Similarly, the maximum speed for a typical pontoon is 36 knots or 41 mph i.e 65 km/hr.

Beyond that, they become highly unstable and risky to operate. But the world’s fastest pontoon boat goes as far as 99 knots or 114 mph. It was a 25-foot triple pontoon with three Mercury Pro Max 300x engines.

Although they are not always pushed to their limits. The optimal speed for a pontoon is 22 mph or 19 knots i.e 35 km/hr.

Maximum Boat Speed For Typical Boat Types

How do you calculate the average speed of a boat, is 30 knots fast for a boat, pontoon speed chart, what happens if the speed is too high.

Having the fastest boat doesn’t mean you always go for that 275.97 knots record. In fact, all motorboats are designed with speed as one of the key parameters to meet.

Even that we enjoy to go a bit faster than usual boats go; for the most part, we try to play safe.

Maybe that is why for the most time different boats run at their optimum speed. This sometimes referred to as the average speed for that vessel. For example, the average speed for pontoons is 22 mph.

This can be calculated by following the Crouch’s Planing Speed formula followed by practical observation. The speed formula gives us information about the hull speed.

This is the speed up to which waves generated by boats or ships; does not restrict its movement or simply limit its speed. It is not that the vessel cannot cross that speed limit.

But it is the speed after which boats get less and less forward movement with the power added.

One of the most accurate and well-known methods to calculate boat speed is using GPS. Other method includes using Dopler effect or Doppler shift and correlation velocity log.

For the doppler log or correlation velocity log, the average speed of the vessel is mean of the optimal speed ( the speed at which the vessel operates most of the time ).

For example, even if your boat max cruise speed was 40 mph but for the most time, it operates between 18 to 24 mph. Its average speed will be 21 mph { (18+24)/2 = 21 }.

Going fast in a boat can be great fun especially when you are with your friends or just competing. For average adrenaline-seeking boaters, it is a huge plus as it brings both thrill and enjoyment.

They try to take their boat to their maximum limits; many a time ignoring the stability or safety issues. But some want to play it safe while still love the adrenaline rush that comes with speed.

So, it is obvious to ask whether 30 knots is fast for my boat? Whether it’s still slow, fast or in between; you should know is it still safe and economical for your boat type .

For most boats especially those built for speed; they can easily surpass 30 knots under the right conditions.

For example deck boats, pontoon, center console boats, Runabout Boats can run at 30 knots for a longer period of time without any negative impact on its stability or its efficiency.

On the other hand for boats such as a trawler, tug, dingy, sailboats and ski boats the speed of 30 knots is too fast, unsafe and uneconomical. But boats such as yacht and ferry it’s fast, safe but uneconomical.

So it depends on whether 30 knot is fast for your boat or it’s just average speed. But if you’re talking about average speed for different boats; yes 30 knot is fast enough to give the thrill.

How Fast Will A 200 hp Pontoon Go?

You will be surprised to know pontoons are sufficiently fast to be used for most water sports. Whether its Speed Tubing, Wakeboarding or Water ski a typical pontoon boat is capable of its function.

A typical 26 feet pontoon with 200 hp motor easily reach speeds up to 40 mph. Even under full load conditions, you can go to 30 mph. From my experience, the optimum speed for water sports is 15 to 35 mph.

So your pontoon might be a little slow but will be just fine for any water sports you like to do.

While adding an additional motor or upgrading to a higher power helps. It is the load that restricts overall speed. In a study, it is been said that for every 1000 pounds your pontoon speed is limited by 12-15%.

If you are looking to upgrade your boat motor I suggest you follow this thumb rule; you need to double the power for the speed increased. For example, if you need to double your current speed just quadruple your boat power.

I find this rule back in 2016 reading on different forums. So it’s not scientifically proven but gives a rough estimate; that I find on three occasions quite close to what reality.

The other way to increase your pontoon speed by adding another pontoon/tube in between; thus converting it to a tritoon. Let’s look at the pontoon boat speed chart for some well-known pontoon brands.

If you are like me who likes to go for recreational boating or at least been on a boat in a lifetime. Then you must know a boat is somewhat unstable at rest, but it gains stability as it starts to move.

But do you know your boat can be highly unstable if the speed is too high?

Traditionally stability of a boat or ship is calculated at rest. Which is generally affected by factors such as; free surface, displacement mass, metacentric height, heel, trim, sea condition, etc.

But since ships and boats constantly move its hydrostatic and hydrodynamic characteristics; undergoes significant change with changing center of buoyancy, underwater volume, and pressure distribution.

For a boat or ship, the restoring moment varies with change in speed. Initially, it increases with the increase in speed; then the rate of change decrease and came to a fixed point.

From there on increase in speed has a negative impact on the restoring moment and the vessel becomes more and more unstable with increasing speed.

There is also a change in linear and nonlinear roller damping coefficient. That too affects the ship’s stability as the speed becomes too high.

In other words, vessel stability increase with an increase in speed to a point. Then it stays comparatively constant for some time and decreases with a further increase in speed.

If you do not believe what I say you can see this youtube video and judge on yourself; how too much speed can be sometimes dangerous for yourself and others on board.

How Fast Can a Boat Go?

TECHNOLOGY — Transportation

Have You Ever Wondered...

• How fast can a boat go?
• When was the last time a world record was set for the fastest boat?
• Where would you go if you had the world's fastest boat?
• acceleration ,
• composite ,

Today’s Wonder of the Day was inspired by levi. levi Wonders , “ how fast can boats go ” Thanks for WONDERing with us, levi!

Have you ever gone for a ride on a boat ? When you think of boating, what comes to mind? Do you think of a leisurely paddle in a kayak or canoe ? Maybe a luxury vacation on a cruise ship or on a river houseboat ? Perhaps a skiing adventure behind a speedboat?

Many boats are known for moving at a leisurely pace. For example, barges aren't known for speed, but they slowly and consistently move large loads of goods from one place to another along the nation's waterways.

Other boats, though, were definitely made for speed. When you think of going fast, you might naturally think of a race car or an airplane, but boats can move, too!

How fast can a boat go? You might be surprised! Currently, the world record for fastest speed by a boat is 317 miles per hour (510 km/h). That's right! Over 300 miles per hour…

That record was set in 1978 by Australian Ken Warby in his speedboat called Spirit of Australia . And that speed was an average speed for a closed course. Warby's maximum speed during his record-setting run was over 350 miles per hour (563 km/h)!

With all of the advances in technology the world has seen over the past 30 years, one might WONDER why the record has stood for so long. Part of the reason is that breaking the record is one of the world's most dangerous pursuits.

Only two official attempts have been made to break the record since 1978. Both attempts ended in boats crashing when they became unstable at speeds approaching 300 miles per hour (483 km/h). Tragically , the drivers of both boats died during these attempts.

The record is still coveted by speedboat racers, though. There are several boats being built and tested today that could one day challenge the record. Unlike gasoline-powered engines that propel most boats you're familiar with, these futuristic speedboats boast jet engines and space-age composite bodies that make incredible speeds a reality.

Wonder What's Next?

If all the fairy tales got mixed up, what stories would they tell? Let’s find out tomorrow in Wonderopolis!

Wow! Today's Wonder of the Day just sped by, didn't it? But the learning can continue if you check out one or more of the following activities with a friend or family member:

• Have you ever seen a speedboat strut its stuff out on the open water? It can be so much fun to watch a fast boat cut a path through the water, leaving huge waves in its wake. For a peek at some cool speedboats, check out the Flickr speedboat photo gallery . Which boats do you think are the coolest? Why?
• Just imagine it…you're at the helm of the world's fastest boat…with nothing but open ocean in front of you. Where would you go? What would you want to see? Grab a friend or family member and get ready to explore the waterways of the world. Find a globe, an atlas or search online for a world map to explore. Can you believe how much of Earth is covered by water? If you wanted to see even a tiny percentage of the waters of the world, you'd need a really fast boat. Would you rather tour the tropical waters near the equator ? Or do the cold seas of the Arctic sound inviting? Explore the waterways of the world through maps. Make a list of the top ten watery locations you'd visit if you could. What is it about those places that interests you?
• Up for a challenge? Calculate the distance you would travel if you were to visit all the places on your “must see" list by boat. If you had a boat that would travel 200 miles per hour (322 km/h), how long would it take you to make your trip? Research the gas mileage you could expect from an average boat engine and try to calculate the fuel cost for your trip, too!

How Fast Can a Boat Go? (Chart)

Many people talk of how motorcycles, cars, trains, and planes go fast. But did you know there’s much fun when you know about boat speeds? Do you ever ask yourself how fast the boat you are using can go?

Well, it’s time to get some answers. Here, we’ll respond to the common query, how fast can a boat go?

Like cars or trains, many factors affect how fast your water vessel can move. Some people love using boats to move at a slow pace. It’s when you’ll use the craft to sail or kayak.

When you love to go fast, you’d want to know a boat’s top speed. So, let’s start with the average speeds of vessels.

Table of Contents

Basic Average Speed for Boats

How to calculate the boat’s speed, what factors can affect a boat’s speed.

The average speed for all boats will vary with the vessel you choose. As long as your boat uses a motor, expect it to go fast. Also, the sailboats move fast but not like the powerboats.

Today, the fastest boat is the Spirit of Australia. It set the record of 345 mph in 1978.

This vessel is a custom type with jet engines instead of propellers . So, don’t expect it to represent the average speeds of most crafts.

Many people love to use recreational boats like sails and pontoons. These vessels move at speeds of 10 to 40 mph.

If you’d love to use a speed boat , expect to get one that hits a top speed of 100 mph. That’s way much faster than the recreational crafts.

So, below is a chart of the average and top speeds of different boats. It will help you pick the best vessel, especially when you love to speed.

Looking at this chart, you’ll see that most boats move at a top speed of 50 mph. Remember, these speeds are subject to change as boat firms make new crafts. You can also customize your vessel to move faster.

It’s safe to never ride past your boat’s top or average speed. Each boat model and type have a different kind of speed.

So, how can you calculate your vessel’s top or average speed? Well, most boat riders and owners use Crouch’s Planning formula.

You’ll can also this formula in the Omni Calculator. It’s what most boat firms use to know how your boat’s hull can perform.

With the Omni Calculator, you can make matters easier. This software will calculate the craft’s speed using the boat’s displacement and power.

The mode will give you the best info about how fast your hull can move. Also, the method needs you to observe your boat.

You can also use the Doppler shift way. It works well with the correlation velocity log.

Here, to get the average speed, you’ll use the mean speed your vessel moves every time. For example, if your boat moves at 20, 22, and 24 mph, its speed is 22 mph.

The Doppler’s shift way’s formula is simple. Remember, it doesn’t matter even if your vessel ever hits a top speed of 50 mph.

After understanding how fast your boat can move, you should know what can limit your boat’s speed. Expect to learn more about how to handle your craft. Here are the aspects that make a vessel move slow or fast.

1. Hull and Bow Design

Your boat’s length will decide if it can move slow or fast. It’s a basic boat rule that the longer the boat’s hull, the quicker it can go.

Also, when your craft has a planning hull and a narrow bow, it won’t push away the waters. So, the boat will move fast .

A planning hull moves on water instead of pushing it away. This act makes the vessel have less friction with the water.

If your vessel has a monohull, it will move more water away. So, it will have more contact with water, thus making it move slowly.

The more contact the boat’s hull has with water, the more friction it will have. Remember, more friction means you’ll move at slower speeds.

Most boats with the monohull move at 4.5 to 7 mph. But if your vessel has a planning hull, expect it to have average speeds of 35 to 59 mph. Racing boats use the planning hulls.

Even if the length and design are key factors, you should measure the speeds to the boat’s weight and width. Let’s see how the weight can make your boat move fast.

Your boat’s weight can create more friction between the hull and water. The boat will move at a slow pace when heavy.

A heavy vessel will displace more water around it to get space. This move creates more friction and needs more time and power. So, your vessel will move at slow speeds and low speeds.

Remember, the space your boat displaces on the water is the same as its weight. If the vessel weighs 2000 lbs., expect it to move water that weighs 2000 lbs.

Sometimes when you add more weight to water, it won’t be easy to notice. The deeper waterlines from the displacement will make it hard for your boat to clear water currents.

3. Hull’s Shape

A hull’s shape will affect how fast your vessel can move. Here, the boat’s speed will relate to the water resistance that your hull will create.

Expect boats with a round and flat bottom hull to have low speeds. Many fishing boats , sailboats, and pontoons have this hull. Firms design such watercraft to move at smooth and slow speeds.

As for the V-shaped and deep V-shaped crafts, they move at high speeds. These shapes are common in racing boats.

The deep V and V-shaped boats have a planning hull. So, they always move fast , even on solid water waves.

Some pontoons and catamarans have the multi-hull. The hulls can be planning or monohulls. Yes, they are ever stable, but your boat can either move slow or fast.

4. Type of Engine

Like cars and planes, the type of engine your boat uses will determine how fast it can move. Some sailboats can move faster than motorboats.

Also, some pontoons move slower than a sailboat because they have less potent engines. Engines with more horsepower will propel your vessel to move fast.

Sometimes, your boat can have a powerful engine but won’t move fast. You’ll experience this act when you don’t use the machine well.

Also, you can customize your boat and give it a jet engine. Your boat will move faster than its top speeds.

Some outboards tend to be faster than the inboard engines . So, the brand you choose for your vessel will affect the speeds.

5. Water Depth

How deep the waters go will impact the speeds. When you ride on shallow waters, your vessel will move at a slow pace.

When you ride on shallow shores, the waters under the boat move fast and reduce the pressure under the vessel. More pressure means your craft will sink.

Your boat will need more draft because of sinking. As it sinks, it displaces more water.

Expect more friction between the water and vessel. So, your boat will use more power to push the water. This move reduces the vessel’s speed.

The water velocity will increase because the boat will be riding closer to the waterbed. Remember, Bernoulli’s principle states that when the velocity in water is high, there will be low pressure at that point.

6. Water Temperatures

Your boat’s speed will be high when you ride on waters with high temperatures. But riding on cold water, during winter, when it’s raining or night, the speed will reduce.

As the heat levels drop, water becomes dense. It means that the water molecules become thicker. So, it will be harder for your boat to move fast.

Thick water molecules bring more friction between water and the boat’s hull. Remember, you won’t notice how the heat levels will affect the speed.

7. The Wind

The wind can reduce or increase your vessel’s speed, even if it uses a motor or not. Your boat will move fast when there’s less wind resistance.

When there’s more wind resistance, the water currents may not favor you. This factor mainly affects the sailboats.

If you want to sail fast , look at the wind direction to see the strength of the water currents. Boats with high hulls tend to drift at high speeds, even in harsh winds.

Also, riding in strong winds can be dangerous. So, you should sail at slow wind speeds when you want your boat to move fast and safe.

You should know how fast your boat can move. It will depend on the type of boat . Vessels like pontoons move slower than racing boats.

Many ways can help you know your boat’s average or high speed. Crouch’s formula is the best way you can use it.

It’s safe to know the top speeds of your boat. This move will make your boat more stable.

The boat’s hull shape and design, weather, and engine can reduce or increase the speeds. When you are keen on these factors, you’ll understand better how your vessel operates.

Do you now know how fast your boat can go? Remember to let us know about it.

How Fast Can a Boat Go? The Answer May Amaze You!

Written by J. Harvey / Fact checked by S. Numbers

Question: How fast does a speed boat go?

Answer: The fastest boat speed on record is 345mph. While commercial speed boats can go as fast as 170mph, different boat types have differing average and top speeds.

People often talk about how fast cars, motorcycles, and aircraft can go. There is such a fascination with vehicle speed that the inquiry is all but guaranteed when certain vehicles become the topic for conversation.

But what about boats? Have you ever thought to yourself, “how fast can a boat go?” In this article, we’ll talk about boat speeds and the different things that affect the speed of a boat.

Either you plan to be a boat owner or want to figure out your current one’s speed, keep reading to find out more.

Table of Contents

Boat Speeds

Boat speed calculation, 1. speedboats – 70mph, 2. pontoon boats – 10 to 25 mph, 3. yachts – 50mph, 4. sailboats – 8 – 12mph, 1. boat length, 2. size and weight, 3. hull shape, 4. propulsion, 5. other factors.

When talking about vehicle speed, it’s always fun to wonder about the fastest speed for vehicles of their kind. The fastest boat speed – the Spirit of Australia, set the current world record of 345 miles per hour back in 1978.

However, this speed is not representative of the speed expected of boats as the Spirit of Australia is a custom-made boat that used jet engines. For commercially available boats these days, speeds of over 170 mph would be considered the fastest speed range.

While looking at certain figures for top speeds is easy, establishing an average boat speed is much more difficult. There are many different types of boats, and each type would have a diverse range of expected top speeds and average speeds.

Below, you’ll find a few boat types and average speeds for each type. By looking at these boat figures, it will be easy to see how vastly different their speed ranges are and why it’s challenging to come up with a single average speed of a boat.

Some websites offer ways to calculate boat speed, such as a pontoon boat speed calculator or those for speed boats, but they’re still tricky to use as each model ends up having to use different variables.

√(shaft horsepower /weight) x boat constant = boat speed

The formula above is the simplest formula to calculate boat speed. It uses many of the factors mentioned above converted to numerical values. However, the result is a theoretical figure that does not take into consideration most environmental factors.

Additionally, variables differ from boat to boat, making it impossible to make a representative figure for boats using a single calculation.

It would be much easier to find a boat speed calculator. Still, the figures these calculators require are hard to acquire, and contacting the boat’s manufacturer would be the only reliable option. Whether they have such information on hand is a different matter.

Average Speeds of Boats

Speedboats are the fastest boats, with top speeds reaching over 170mph. These are commercial speeds, however, as custom speed boats can reach much higher speeds. With their sleek body and high-powered engines, these motorized boats are the symbol of speed on the water.

Average speeds for speedboats are at around 70mph, although high-performance models are expected to reach over 100mph. Since speedboats are known for their speed, there is a huge difference in performance between standard models and luxury ones. Not that speedboats are in any way regular as they are the equivalent of sports cars to boats.

Pontoon boats aren’t known for their speed since they’re usually associated with taking it easy and the occasional relaxed touring, though some can go over 30 mph. Not much compared to speedboats, but that’s faster than many would think them capable of going.

Since pontoon tubes make these boats wide, it doesn’t help as far as fast speed is concerned, making it difficult to reach higher speeds. An average speed of around 20 to 25 mph doesn’t take much away from them, though since a leisurely 10 to 15 mph already suffice.

With their wide range of available lengths and varying sizes, it’s also difficult to establish a good average speed for yachts. Ranging from 25 to over 70 feet long, there can be such wide gaps in average figures.

They tend to get tied down by how big they get, but they can also carry bigger and more powerful engines. Currently, the top speed for yachts is 80mph but yachts that reach 50mph are considered extremely fast.

Sailboats are somewhat different from the other boat types on this list as they don’t have engines. While average motorboat speed is greatly affected by its engine, sailboats propelled by wind and sail are expectedly slower.

Average sailboat speeds sit at 8mph and top out at around 12mph. These figures may not seem impressive but needing no engine to travel is itself impressive.

Historically, the fastest sailboats reached a maximum speed of a little over 30mph. These boats brought goods and cargo to different cities in the 19th century and relied on travel winds.

Factors That Affect Average Motor Boat Speed

The length of a boat directly affects its speed. A longer boat is usually a faster boat. However, We must also measure the length of a boat in contrast to its width and weight. Length in relation to hull design allows a boat to effectively cut through resistance against water, making a boat run faster.

The size and weight of a boat both matter because both contribute to the resistance between the boat and the water. A heavier boat displaces more water, but the deeper water line also makes it more difficult for the boat to clear the waves of water along its hull, which is important to gaining faster boat speed.

Hull shape is another factor that has a lot to do with water resistance. While reducing this resistance is a major aspect in designing a hull, it is not the only important point for consideration. Not all boats demand speed, after all.

Pontoon boats are created to accommodate certain functions and amenities. Boat function is a critical consideration, and there are many instances where boat speed is but secondary.

As far as hull design goes, boat constants and slip percentages also change depending on each boat.

What powers a boat is another big factor that affects the speed of a boat. A motorized boat is almost certain to be faster than a sailboat, but other factors come into play. There are still sailboats that can beat out motorized boat speed, especially compared to pontoons or similar water vehicles.

Appropriate use of propulsion also comes into play. A boat with an overpowered engine may end up being unstable and unable to utilize the power of the said engine properly. It can also be dangerous to use such a boat.

There are numerous other factors that affect boat speed. Wind speed, water conditions, even water density can contribute to and affect the speed of your boat. Wind resistance, water-resistance aside, greatly affect boat speed even with the power afforded by high-performance engines.

How fast can a speed boat go? This question cannot be addressed so easily, even when a boat is equipped with such a powerful engine. There are numerous factors that all come into play.

After reading all these about boat speed, hopefully, you come to appreciate the wonder of boat speeds as you would for cars and aircraft. It’s a fascinating topic, boat speed calculation aside, that doesn’t get to share the spotlight as often.

Video shows moments before superyacht went down in storm off Sicily

Newly released video captures a luxury superyacht being battered by a violent storm before it suddenly sank off Sicily with 22 people aboard Monday.

The grainy images obtained by NBC News and other outlets were recorded on closed-circuit television not far from where the Bayesian was anchored, about a half-mile from the port of Porticello, on Sicily’s northern coast .

The yacht's 250-foot mast, illuminated with lights and lashed by the storm, appears to bend to one side before it finally disappears and is replaced by darkness.

The speed with which a yacht built to handle the roughest seas capsized stunned maritime experts.  

“I can’t remember the last time I read about a vessel going down quickly like that, you know, completely capsizing and going down that quickly, a vessel of that nature, a yacht of that size,” said Stephen Richter of SAR Marine Consulting.

British tech tycoon Mike Lynch and five of the 22 other people who were aboard the 184-foot vessel remain unaccounted for and are believed to be trapped in the Bayesian’s hull, nearly 170 feet underwater.

Officials confirmed Monday that at least one person, the ship’s cook, had died.  

Superyachts like the Bayesian, which had been available for charters at a rate of $215,000 a week, are designed to stay afloat even as they are taking on water to give the people aboard a chance to escape, Richter said. 

“Boats of this size, they’re taking passengers on an excursion or a holiday,” Richter said. “They are not going to put them in situations where it may be dangerous or it may be uncomfortable, so this storm that popped up was obviously an anomaly. These vessels that carry passengers, they’re typically very well-maintained, very well-appointed.”

Built by Italian shipbuilder Perini Navi in 2008, the U.K.-registered Bayesian could carry 12 guests and a crew of up to 10, according to online specialist yacht sites. Its nearly 250-foot mast is the tallest aluminum sailing mast in the world, according to CharterWorld Luxury Yacht Charters. 

On Tuesday, Italian rescue workers resumed the search for Lynch and the five other passengers still missing: Lynch’s 18-year-old daughter, Hannah; Morgan Stanley International Chairman Jonathan Bloomer and his wife; and Clifford Chance lawyer Chris Morvillo and his wife.

“The fear is that the bodies got trapped inside the vessel,” Salvatore Cocina, the head of civil protection in Sicily, told Reuters .

The Bayesian is owned by a firm linked to Lynch’s wife, Angela Bacares, who was one of the 15 people rescued Monday after it capsized.

“It’s extremely rare for a boat of this size to sink,” Richter said.

What’s not rare is the kind of storm that sank it , said Simon Boxall, senior lecturer in oceanography at Britain’s University of Southampton.

“People assume the Mediterranean is this rather calm and passive place that never gets storms and always blue skies,” Boxall said. “In fact, you get some quite horrendous storms that are not uncommon at this time of year.”

The president of Italy’s meteorological society has said Monday’s violent storm may have involved a waterspout, essentially a tornado over water, or a downburst, which occurs more frequently but doesn’t involve the rotation of the air.

Luca Mercalli, president of the Italian Meteorology Society, also said recent temperatures may have been a factor. 

“The sea surface temperature around Sicily was around 30 degrees Celsius [86 Fahrenheit], which is almost 3 degrees more than normal,” Mercalli told Reuters. “This creates an enormous source of energy that contributes to these storms.”

The Mediterranean sailing vacation was designed to be a celebration for Lynch, who two months ago was acquitted by a San Francisco jury of fraud charges stemming from the 2011 sale of his software company Autonomy to Hewlett-Packard for $11 billion.

Prosecutors alleged that Lynch, dubbed “Britain’s Bill Gates,” and Autonomy’s vice president for finance, Stephen Chamberlain, had padded the firm’s finances ahead of the sale. Lynch’s lawyers argued that HP was so eager to acquire Autonomy that it failed to adequately check the books .

Lynch had taken Morvill, who was one of his defense attorneys, on the luxury trip. 

Chamberlain was not on the Bayesian.

In what appears to be a tragic coincidence, a car struck and killed Chamberlain on Saturday as he was jogging in a village about 68 miles north of London, local police said.

“Steve fought successfully to clear his good name at trial earlier this year, and his good name now lives on through his wonderful family,” Chamberlain’s lawyer, Gary Lincenberg, said in a statement .

Nimitz-Class Aircraft Carrier: How Fast Can It Go (Or Flank Speed)?

Summary and Key Points: The top speed or flank speed of the U.S. Navy's Nimitz-class nuclear-powered aircraft carriers remains somewhat of a mystery, with official figures stating they can exceed 30 knots.

-It is believed they can reach up to 31.5 knots, fast enough to cover a large area quickly.

-According to firsthand accounts, it takes around 10 minutes for these massive 97,000-ton warships to reach flank speed, and while no one has officially attempted to water ski behind an aircraft carrier, it would be possible given their impressive speed.

How Fast Can U.S. Navy Aircraft Carriers Really Go?

The United States Navy's largest vessels are also among the fastest surface combatants in service today – the question however is exactly how fast the nuclear-powered Nimitz-class super carriers can travel. Officially the United States Navy will only state that its carriers can exceed 30 knots, but how much remains unknown.

It is known that the Nimitz class was designed to produce 260,000 shp , while there is speculation the design speed was 31.5 knots – fast enough to get out of harm's way.

As Forbes.com reported in 2019 , "Because they can sustain speeds of 35 miles per hour, the Nimitz-class carriers populating the current fleet can move to anywhere within a 700-square mile area within 30 minutes. After 90 minutes, that area grows to over 6,000 square miles."

Reaching Flank Speed

However, it should be noted that warships aren't always operating at "flank speed," the vessel's maximum, and it takes time to get a 97,000-ton warship moving. Recently a tactical officer shared some insight on the 'flank speed' of the U.S. Navy's supercarriers on the Quora social messaging platform.

Ross Hall, tactical action officer and anti-submarine officer assigned to a U.S. Navy Nimitz-class nuclear-powered supercarrier offered insight on the subject and was quoted by TheAviationGeekClub.com .

"It's hard to imagine what a carrier doing flank speed is like," Hall explained in his post . "During our transit to the North Arabian Sea, we conducted a rendezvous in the Indian Ocean with an amphibious group that was transiting back to the US. That day, the amphib guys showed off their LCACs, and we gave them an impromptu air show, with a couple of fly-bys for good measure."

Hall added, "As we parted company, our skipper announced 'Let's show them what an aircraft carrier can do'. We were barely making way at the time. He ordered us to depart at flank speed," noting, "When flank speed is ordered, power is applied to the shafts to turn the propellers. On the Nimitz class carriers, the four propellers are approximately 25 feet in diameter, and each weighs about 30 tons. When power is applied, torque on the shafts is limited to prevent damage – the shafts can 'twist' up to one and a half times (540 degrees). The longest shafts are 184 feet long.

"When the propellers start to turn, the water behind the ship begins to churn – it looks like the sea is beginning to boil. You can feel the ship vibrating as the engines ramp up and the propellers start to rotate," his comments continued.

The naval officer said it took about 10 minutes for the warship to reach flank speed, and he added, "If you have a long enough cable and a death wish, you could waterski behind the carrier."

Could you Water Ski Behind an Aircraft Carrier?

While Hall was clearly joking, he may not have known that in 1986, Royal Navy sailors attempted to water ski behind the Type 42 destroyer HMS Nottingham while deployed to the Persian Gulf. However, that vessel was only capable of reaching a top speed of 18 knots – about half that of the U.S. aircraft carrier.

Images have also circulated online that show the Royal Navy's Lieutenant Commander Nigel Williams water skiing from the Type 22 frigate HMS Brave in the 1980s. Yet, to date, there are no reports that any sailors have actually tried to water ski behind a carrier, yet it could be easily done by more experienced water skiers.

The average water skiing speed is about 26 knots, but for the record, according to Guinness World Records , "The fastest water skiing speed recorded is 230.26 km/h (143.08 mph) by Christopher Michael Massey (Australia) on the Hawkesbury River, Windsor, New South Wales, Australia on 6 Mar 1983. His drag boat driver was Stanley Charles Sainty.

Massey could certainly have water skied behind the USS Nimitz (CVN-68), even at flank speed.

How did the superyacht Bayesian sink? Experts say weather was just one factor

Divers searching for 6 missing people locate 5 bodies inside wrecked yacht's hull.

Social Sharing

A complicated search effort is underway deep beneath the surface of the Mediterranean Sea, off the coast of Italy, where a superyacht sank early Monday during a fierce storm. 

Dive crews are attempting to enter the wreck of the Bayesian, a 56-metre long British-flagged luxury vessel, which is sitting in some 50 metres of water near the Sicilian fishing village of Porticello.

Fifteen of the 22 passengers and crew members on board were rescued. Divers searching for six people considered missing, including British businessman Mike Lynch, located five bodies inside the yacht's hull on Wednesday, and retrieved four of them from the water.

Searchers previously recovered the body of Recaldo Thomas, the ship's Canadian-Antiguan cook, in the water not far from where the Bayesian sank.  

• Diving team finds 5 bodies in Sicily yacht search
• Canadian dead, several others missing after superyacht capsizes off Sicilian coast

Questions have emerged about why a boat designed to handle severe weather sank so rapidly and whether or not some of its features could've been a factor in its demise. Maritime experts say investigations may, in time, reveal what led to the disaster.

"There needs to be an investigation as to why this happened, what went wrong and, you know, how to prevent it in the future cases," said Simon Boxall, an oceanographer and senior lecturer at the University of Southampton in England.

Canadian dead, others missing after superyacht sinks near Sicily

How did the bayesian sink so quickly.

Grainy footage from closed-circuit cameras on the shore broadcast on the website of the Giornale di Sicilia newspaper showed the Bayesian's majestic mast just before it disappeared. 

Karsten Borner, captain of the Sir Robert Baden Powell, which rescued the survivors who managed to get into a lifeboat, told The Associated Press he was close enough to be able to see the Bayesian as the storm came in.

"A moment later, she was gone," he said.

The survivors told the rescuers they went flat on the water "and were sunk in two minutes."

Boxall said vessels rely on being able to steer and navigate stormy seas, but the Bayesian was anchored and stationary, which likely made it more vulnerable to the storm and, potentially, a waterspout , or mini tornado that creates a whirlwind over the surface of the sea. 

He said it was also dark, meaning "you wouldn't see this sort of very unique event coming towards you."

CCTV footage shows yacht Bayesian as deadly storm strikes

"It's a freak of nature," Boxall said. "I think the fact that so many have survived, so far, is probably a miracle."

Tom Sharpe, a retired Royal Navy commander and defence commentator, told CBC News the weather was likely not the only issue.

He says it's rare that a weather event like this takes down a boat. 

"There's nearly always a sequence [of events]," he said in an interview from Guildford, England, explaining that everything from safety protocols to the culture on board the vessel needs to be taken into account. 

Was the boat's design part of the problem?

The Bayesian was built in 2008 by Italian luxury yacht maker Perini Navi.

Andrea Ratti, a nautical design professor at Milan Polytechnic, told Reuters that a boat the size of the Bayesian could only sink so rapidly by taking on a huge amount of water. 

He suggested that one or more portholes, windows or other openings may have been broken or smashed open by the waterspout, letting in water. There has also been media speculation that a major hatch might have been inadvertently left open.

Reports have also highlighted that the Bayesian featured a 72-metre mast — one of the tallest in the world. 

Ratti said an unusually tall mast is not by itself an element of vulnerability in a storm. 

A second expert, structural engineer Filippo Mattioni, was also skeptical about the suggestion the boat may have sunk due to a broken mast, which likely would have caused major damage smashing against the hull.

Fire department diver Marco Tilotta told the newspaper Il Messaggero that the wreck was "apparently intact," with "no gashes, no signs of impact." However, only half of the hull is visible to divers.

The Bayesian also had a retractable keel — the fin-like structure under the hull that helps stabilize boats and acts as a counterweight to the mast. 

Both Ratti and Mattioni wondered if the yacht had been anchored with the keel up, reducing the vessel's depth under water and making it less stable. Ratti said strong winds might have caused the boat to start oscillating wildly, "like a pendulum," putting exceptional strain on the mast.

Sharpe pointed out that a mast the size of the Bayesian's is designed for a massive sail, and without that sail raised and catching the wind, the gusts likely would've had a negligible impact on the aluminum pole.

• What we know about the capsized superyacht off the Sicilian coast

He instead suggested the anchor may have played a pivotal role.

"My kind of working assumption is that she was probably a bit further in at anchor, and it's very likely, in these sort of conditions, that her anchor dragged," he said. 

In such a situation, he said, a crew is better off steering toward the anchor to stabilize the vessel or raising the anchor and heading out to sea to ride out the storm.

"They might have got caught in that middle ground where they're not on a particularly good anchorage, but the anchor is now controlling the bow of the ship."

Sicily superyacht rescue: What divers are up against | About That

What caused the extreme weather.

Although Sharpe says the weather is unlikely the sole cause of the sinking, he notes the Mediterranean isn't the calm sea often pictured in travel brochures. 

"It can get pretty nasty," he said.

The type of storm that struck Monday is fuelled by warm water and the Mediterranean is warmer than ever, said Boxall, noting there's been about a three and a half degree increase in the 20-year average temperature.

'The ship behind us was gone,' says captain who rescued yacht passengers

Climatologists say global warming is making such violent and unexpected tempests more frequent. 

Luca Mercalli, president of Italy's meteorological society, said the sea surface temperature around Sicily in the days leading up to the shipwreck was about 30 C. 

"This creates an enormous source of energy that contributes to these storms," he told Reuters.

Kingston-to-Seattle fast ferry service canceled until further notice

Kitsap Transit has canceled all sailings on its passenger-only ferry service between Kingston and downtown Seattle, citing a mechanical failure with one of its vessels.

Passholders can ride Washington State Ferries instead by checking in with an agent at the Seattle ferry dock , Kitsap Transit said in a rider alert issued Sunday. Passengers can then take a bus between the Bainbridge Island ferry terminal and Kingston.

However, Washington State Ferries has canceled its 8:45 a.m. ferry out of Bainbridge and 9:35 a.m. out of Seattle due to a shortage of crew.

Kitsap Transit said it had been running its fast-ferry service using the Rich Passage 1 boat, since the primary vessel for the Kingston-to-Seattle route is getting repaired.

But due to mechanical issues with a different vessel, Kitsap Transit said it is canceling the Kingston route so the Bremerton-to-Seattle route can remain a two-boat service.

In the meantime, the Bremerton and Southworth routes are operating without backup vessels, Kitsap Transit said. That means more sailings could be canceled if any vessel on either route is taken out of service.

Data showed more than 12,800 passengers rode the Kingston fast ferry in July, with an on-time performance of 97%. Six sailings were canceled in July due to a mechanical issue.

Two ferries, the Enetai and Commander, have been out of service because parts failed in the boats’ propulsion systems.

Kitsap Transit estimates the Enetai will be out of service until at least mid-November. The Commander was taken out of service after the Enetai, and is not expected to return until early 2025.

The maker of Mike Lynch's yacht says it took 16 minutes to sink and the crew should have had time to rescue passengers

• Mike Lynch and six others are dead after his superyacht sank off Sicily's coast.
• The Bayesian sank during a storm. The Italian Sea Group CEO said the yacht took 16 minutes to sink.
• Giovanni Costantino told the Financial Times the ship was "designed to be absolutely stable."

The maker of Mike Lynch's doomed superyacht said the luxury sailing vessel was "absolutely stable" and never should have sunk as he blamed the crew for an "incredible mistake."

The 183-foot ship — named the Bayesian — sank during stormy weather near Palermo, Italy, in the early hours of Monday local time.

Fifteen people, including Lynch's wife , were rescued, while seven others — including Lynch, a UK tech tycoon — have been confirmed dead.

Divers discovered the body of the final person missing from the superyacht on Friday, the Italian coast guard said, according to reports. The Washington Post and CNN both reported that the last body found was believed to be Lynch's 18-year-old daughter, Hannah.

Giovanni Costantino, the CEO of the Italian Sea Group, which owns Perini Navi, the firm that built the Bayesian in 2008, said the ship was "designed to be absolutely stable" as it had the second-tallest mast in the world.

"The torture lasted 16 minutes. It went down, not in one minute as some scientists have said. It went down in 16 minutes," Costantino told the Financial Times . "You can see it from the charts, from the [Automatic Identification System] tracking chart."

Business Insider could not independently verify his statement, and Costantino did not immediately return requests for comment.

Costantino added that the yacht's skipper "should have locked everything up, saying: "He should have gathered all passengers in the safe point. This is protocol. No one should have been in their cabin."

In an interview on Thursday with Reuters , Costantino placed the blame for the deadly tragedy on the yacht's crew members, saying that they made the "incredible mistake" of not being prepared for the powerful storm that rolled in.

"This is the mistake that cries out for vengeance," Costantino told Reuters, which reported that the storm was projected in shipping forecasts.

Maritime legal experts previously told BI that the operator of the sunken yacht should lawyer up in anticipation of claims from families of the dead or the survivors themselves.

"The boat suffered a series of indescribable, unreasonable errors; the impossible happened on that boat ... but it went down because it took on water. From where, the investigators will tell," Costantino told Reuters.

An investigation into the exact cause of the sinking is ongoing.

Authorities previously confirmed a strong storm had been in the area, though search-and-rescue experts have suggested that multiple factors could have contributed to the disaster.

One theory is that soaring temperatures in the area caused passengers and crew to leave windows and doors open, which would have allowed water to fill the ship quickly during the storm.

"The boat sank because it took on water," Costantino told the FT.

He added that a large opening just above the waterline on the stern could have been left open and become flooded.

Out of the 15 who escaped, nine were crew members. One of them, a chef named Recaldo Thomas, was confirmed dead Monday.

Stephen Askins, a lawyer specializing in maritime cases, told MailOnline that the crew was likely already awake before the ship sunk, while the passengers may have been sleeping below deck.

"The water came in from [hatchways] left open," Costantino told the FT. "There is no other possible explanation. If maneuvered properly, the boat would have comfortably handled the weather — comfortably."

Matthew Schanck, a maritime search-and-rescue consultant, previously told BI that the disaster was "shocking" because Lynch's vessel was a "modern, state-of-the-art superyacht" that would have been commercially certified with the appropriate safety regulations in place.

Witnesses told BBC News they saw a waterspout — an uncommon weather phenomenon consisting of tornadolike wind and water — before the ship went down.

"This tends to have been the accepted theory, that the vessel was hit by a waterspout and the crew didn't see it coming because it was nighttime and dark," Schanck said.

He added that this scenario made sense but questioned how witnesses would have noticed a waterspout if the crew hadn't seen it.
