average speed of a sailing yacht

What is the Average Speed of a Sailboat?

When I try to figure out the duration of whatever sailing trip I have in the making, I always need to know this one thing first: the average speed of a sailboat - especially with long journeys. If you have the same problem, this article is for you.

So what's the average speed of a sailboat? Most sailboats cruise at a speed of 4-6 knots (4.5-7 mph), with a top speed of 7 knots (8 mph or 13 km/h). Larger racing yachts can easily reach speeds up to 15 knots (17 mph or 28 km/h), with an average cruising speed between 6-8 knots (7-9 mph). Cruising speeds of over 8 knots are uncommon.

Different types of sailboats reach very different speeds. Of course, it all depends on wind conditions, current, and many other factors. Did you know that the speed of a boat is directly related to its length? The larger the boat, the faster it goes. I'll explain it to you later on, but first, more on average speed.

On this page:

Factors that determine speed, converting and calculating sailing speed, calculating the hull speed of your own boat, exceeding hull speed, amount of nautical miles, related questions.

So let's get a little more into detail on sailboat speed. The most important factor in determining the speed is the hull type. I have two rules of thumb for you. The first is: the less of the boat is under water, the faster it goes.

Here are the average cruising speeds for different hull types:

• Monohull - 6-8 knots
• Catamaran and trimarans - 9-10 knots
• Fastest monohull (world record circumnavigation) - 15.43 knots
• Fastest trimaran (world record circumnavigation) - 27 knots

Monohull - Your average sailboat is a monohull. Nearly all monohulls are displacement hulls. A displacement hull is under water, pushing the water away. This allows the boat to cut through the water more smoothly; this stabilizes the boat. If you want to make it go faster, you would have to raise the entire hull above the water. Later on I'll show you how to calculate the maximum hull speed of your boat.

Catamarans and Trimarans - These are planing hulls, meaning they are on top of the water. They displace less water, which is why they are faster. But a planing hull is less stable than a displacement hull. To compensate, catamarans and trimarans have two or three hulls, which makes them extremely buoyant. Since this is not your average sailboat I'll leave them out of this article.

The second factor is the length of the boat. It's the second rule of thumb: the longer the boat, the faster it goes. Each sailboat has a maximum hull speed, which it can't exceed (in theory). The hull speed is determined by the length of the boat.

Here are the maximum hull speeds for different monohull lengths:

Please note: the maximum hull speed isn't the average sailing speed. It's the upper limit (in theory - read on to learn more).

The third and perhaps most obvious factor of course is wind direction and speed. If you plan a large voyage, for example, an ocean passage, make sure to check the dominant wind and direction for your time of year. You want to make sure to have as much downwind as you can get, and a favorable current as well. This is why most sailors choose to go eastward instead of westward when sailing the world.

If you want to know why going eastward is smart, I encourage you to read my previous article on sailing around the world here .

How to calculate necessary sailing speed

So imagine you need to get to dock in time. It's 50 miles away. You need to arrive at 2100 hours. It's currently 1500 hours. Would be handy to know at what speed you need to sail to make it in time.

The formula is simple:

nautical miles / time = average speed necessary

2100 - 1500 = 360 minutes 360 / 60 = 6 hours Your average speed should be: 50 NM / 6 = 8.3 knots

Converting knots to mph and km/h

To convert knots to mph or km/h, simply multiply the knots by the ratio below.

1 knot = 1.151 mph 1 knot = 1.852 km/h

Great, we have a good general idea of what to expect from our trustworthy vessels. If you want to go deeper, you can try to calculate the maximum hull speed of your own boat. Calculating the maximum speed is actually very simple. Now is the time to get out your calculator.

You calculate the maximum hull speed (HS) by taking the length in feet (lwl), get the square root, and multiplying it by 1.34.

HS = √ lwl * 1.34 HS = Hull Speed lwl = length at waterline

So a 80 feet boat has a maximum hull speed of:

√ 80 * 1.34 = 12 knots

A displacement hull has a maximum hull speed. Hull speed is a theoretical speed that tells us what the maximum efficient speed is. Everything above that speed costs a lot more energy. If you power your boat by engine, you can exceed the speed by pushing the hull over your own bow wave (this requires a lot of horsepowers though, and it isn't good for your engine).

If you're sailing instead, you can exceed your hull speed with the help of the weather. Let's call these surfing conditions (sounds good). This might happen to you when you're sailing downwind and the current pushes you forward simultaneously. This helps you to overtake your own bow wave. If this happens, the wavelength gets longer than the hull length: the water can't get out of the way fast enough. As a result, the boat starts to plane, increasing water resistance at the front. Congratulations: you're surfing on your own bow wave.

The increase in speed won't be mind blowing however (about 1 knot). The truth is: a displacement hull is bound to its speed. It just costs to much energy to propel it through the water. It's made to cut, not steamroll the water.

Sailboats don't travel lightning fast, but they do travel 24/7. Because of this, they can cover quite a bit of distance. What distance are we actually able to cover with conservative speeds?

The average sailboat covers a distance of roughly 100 nautical miles (NM) , at a speed of around 4.5 knots. This equals 115 miles or 185 km.

1 NM is 1.852 km or 1.151 mile

You can calculate the distance per day by simply multiplying the speed in knots by 24 hours:

NM = knots * 24

Most sailboats cover anywhere between 100-180 NM per day. This means that a fast sailboat in ideal conditions can cover more than 200 miles. Impressive. However, anything over 180 NM is uncommon. We usually only see cruising speeds that high in races.

Here are the distances per day (NM) for different cruising speeds:

How fast can a sailboat go under power? The average speed of a sailboat under power is 4-5 knots (5 mph or 8 km/h). Most sailors switch to engine at sailing speeds below 6 knots, especially when on passage.

How fast do racing sailboats go? Racing sailboats can reach speeds of 30 - 50 knots (35-58 mph or 55-92 km/h). The record is set at 65.45 knots (75 mph or 121 km/h). They can beat wind speed because they have a planing hull instead of a displacement hull, making them a lot faster than average sailboats

Can a sailboat sail faster than the wind? Sailboats with a planing hull (multihulls) can go faster than wind. Displacement hulls (the average sailboat) can't beat the wind, or just slightly in surfing conditions.

Just wondering if you could do a similar article on diesel powered boats.I have a Seaward 23 powered with two 1.6 mermaid engines.I normally do around 7_8 knots and was thinking of replacing them for more speed around 10_12 knots.what engines would I need. According to what I have read already I should be getting 10 knots cruising speed with a top speed of 12 knots.This is not the case and her bottom is very clean.Found your article very interesting.

Shawn Buckles

Hi Robert, thanks for your comment. You have quite a bit of power there, nice.

I wouldn’t know for sure what engine size you should get, this article is specifically about sailboats. Also, this is the maximum hull speed - what you could expect under ideal conditions. And that’s never the case - you have to deal with current, wind, and so on. So I’d say it sounds about right.

If by diesel-powered boats you mean a powerboat, I currently don’t write about powerboats. Maybe I will in the future, but I won’t make any promises for now.

Thanks again and good luck with your upgrade!

I’m not sure if you use a different way of calculating time in nautical terms (Not a sailor myself, just curious about sailboats), but in the ‘How to calculate necessary sailing speed’ my math would say there’s 6 hours = 360 minutes from 1500 hours (3 PM) to 2100 hours (9 PM), not 600 minutes = 10 hours. Am I missing something?

Hi Ben L, That’s exactly right, it was a math error on my part. Thanks for pointing it out, I have updated the article.

Catamarans and trimarans are PLANING boats?! How long have you been sailing? Three days? :-)))

Matas Pacevicius

Just wanted to point out a typo. At hull speed of 5NM you travel 120NM and 138miles (not the 115 written) per 24hrs. Thank you for your articles. I’ve been dreaming of circumnavigation for years and am in the process of designing and building my own sailboat for the feat. I would love to build and sail a sailboat on which I could live almost anywhere in the world. I currently reside on the Gulf coast of Florida and am surrounded by beautiful warm waters that beckon me to explore them. Hopefully in the followings 5 years I will be sailing into the Caribbean in my self-built traveling home in the water. I wish to call the oceans home and soon the entire world. I plan to cross the Atlantic from the Caribbean on my first leg around the world. Would you recommend sailing throughout the Mediterranean? Any ideas on how’s to make money along the way?

I’ve worked all my life, struggling. Now 56y.o. staring at becoming a jobless wanderer in the next couple of months, maybe pick up a used boat. I am just really curious how some people have the time and place to design, build, and then sail around. Tell me your secrets…

Benjamin Lindner

Hello Shawn;

You have an error in your table above: 5 Knots = 120 NM BUT DOES NOT EQUAL 115 MILES.

Thank you Ben

Carlos Alberto Molinelli

But WHY is it a maximum speed for displacement boats in quiet waters, responding to this old formula? It is because the speed increases, the water displaced forms waves. At slow speed there are several along the hull. At fast speed there are only two: one at the bow and another an the stern. If the boat tries to go faster, the stern wave would go more farther but the hull would lose sustentation. It better explained with a picture. Look for boats going fast. You will see only two waves.

Robert Flores

Getting close to retirement and want to get a sailboat with some power. Thinking about sailing lakes and coastal. Looking at the macgregor 26M and seaward 26rk. What recommendations do you have ?? Or things to think about. I am one for safety. Best regards Robert

Ronald Ernst van Dijk

Thank you. Very well explained in clear language, including the usual conversions between knots, miles and kilometers. It helps understanding the physics of sailboats and what to expect in terms of speed. I have just completed building an 18 feet wooden gaff rigged yawl (design by François Vivier) for single handed coastal sailing in Malaysia, the country where I live. Your “rule of thumb” about HS = Lwl * 1.34 seems to work well, although I have to further try it out with different wind speeds and sailing on a reach or down wind.

Your website is an ad horror show to the point it is not usable any more. Ads do have their place and purpose, just like food needs salt. But in your case there is more salt then there is food. Moderation is key.

What Is the Average Speed of a Sailboat (Plus Its Top Speed)?

Sailing is a popular hobby and sport enjoyed by many enthusiasts around the world. The beauty of sailing lies in the challenge of mastering the wind and currents to move a boat forward. One of the fascinating aspects of sailing is its speed. Sailboats can move at varying speeds, depending on several factors. In this article, we will dive into the average and top speeds of sailboats and explore the techniques and strategies to increase sailboat speed.

Quick Facts

Understanding Sailboat Speeds

Before delving into the average and top speeds of sailboats, you need to understand the dynamics of sailboat speeds. Sailboat speeds can be determined by the points of sail, wind direction, and boat design. Points of sail refer to the various angles at which a boat can sail in relation to the wind. These angles include upwind, close-hauled, beam reach, broad reach, and downwind (also called a run). Wind direction plays a crucial role in determining sailboat speed. A tailwind is usually faster than a headwind. The boat design also determines the speed potential of a sailboat.

When sailing upwind, sailboats move slower because they are fighting against the wind. Close-hauled sailing is the point of sail where the boat is sailing as close to the wind as possible. It is the slowest point of sail, as the boat is sailing against the wind. Beam reach sailing is when the boat is sailing perpendicular to the wind. It is faster than close-hauled sailing but slower than broad reach sailing. Broad reach sailing is when the boat is sailing with the wind behind it. It is faster than beam reach sailing but slower than downwind sailing. Downwind sailing is when the boat is sailing with the wind directly behind it. It is the fastest point of sail, as the boat is moving with the wind.

Factors Affecting Sailboat Speed

Several factors influence the speed of sailboats. Wind speed is the most significant factor affecting sailboat speed. The bigger the sails, the more power a sailboat has to move faster. Sail area also plays a crucial role in determining sailboat speed. A larger sail area means more power to move the boat. Boat size and weight also come into play, as larger boats require more power to move at faster speeds. Water friction is another critical factor that affects speed. Friction between the hull and the water can slow down a sailboat, but optimized boat design can minimize this effect.

Boat design is essential in determining sailboat speed. The boat’s hull shape, keel design, and rigging all play a role in how fast the boat can sail. The hull shape affects how the boat moves through the water, and a streamlined shape can reduce water resistance and increase speed. The keel design affects the boat’s stability and maneuverability, which can affect speed. Rigging, including the mast and sails, also plays a crucial role in sailboat speed. A well-designed rig can help the boat capture more wind and move faster.

Measuring Sailboat Speed

There are various ways to measure sailboat speed. The most common method is the use of a GPS or handheld speedometer. GPS offers accurate speed readings, while handheld speedometers are affordable and provide basic speed readings. In sailboat racing, measurements are done using speed logs attached to the boat’s hull or through timed performance over a specific distance. Sailboat speed can also be measured using wind instruments, which measure the wind speed and direction and calculate the boat’s speed based on that information.

Sailboat speed is affected by various factors, including wind speed, sail area, boat size and weight, water friction, and boat design. Understanding the points of sail and how wind direction affects sailboat speed is essential in determining how fast a sailboat can go. Measuring sailboat speed can be done using various methods, including GPS, handheld speedometers, speed logs, timed performance, and wind instruments.

Types of Sailboats and Their Average Speeds

Sailboats come in different designs, shapes, and sizes, each with its unique features and capabilities. Whether you are a seasoned sailor or a beginner, choosing the right sailboat type can make all the difference in your sailing experience. Here are some popular sailboat types and their average speeds.

Dinghies are small sailboats primarily used for recreational sailing. These boats are easy to handle and maneuver, making them a popular choice for beginners. Dinghies usually have a single sail, which limits their speed potential. However, their lightweight design allows them to move swiftly through the water. On average, dinghies can move at speeds of 8-15 knots (9-17 mph).

One of the most popular dinghy sailboats is the Laser, which has been an Olympic class boat since 1996. The Laser is a one-design boat, meaning that all boats are built to the same specifications, ensuring fair competition. The Laser is known for its speed and agility, making it a favorite among sailors around the world.

Catamarans are two-hulled sailboats that have a wide beam, making them stable and fast. These sailboats can achieve high speeds and are popular for racing and cruising. Catamarans have a unique design that allows them to sail close to the wind, making them efficient and fast. On average, catamarans can move at speeds of 15-25 knots (17-29 mph).

The Hobie Cat is one of the most popular catamarans in the world. The Hobie Cat is a small, beach-launched catamaran that is perfect for recreational sailing. The boat’s lightweight design allows it to move quickly through the water, and its unique trampoline design makes it comfortable to sail.

Monohulls are the most common sailboat type. These boats have a single hull and can range from small recreational boats to large racing sailboats. Monohulls are versatile boats that can be used for cruising, racing, and day sailing. The average speed range of monohulls is 5-20 knots (6-23 mph).

The J/Boat is a popular monohull sailboat that is known for its speed and performance. The J/Boat is a racing sailboat that has won numerous regattas and championships around the world. The boat’s lightweight design and high-tech features make it a favorite among competitive sailors.

Cruising Sailboats

Cruising boats are designed for comfort and leisurely sailing. They are usually larger and heavier than other sailboat types and can accommodate large crews. Cruising sailboats are perfect for long-distance sailing and exploring new destinations. The average speed range of cruising sailboats is 5-15 knots (6-17 mph).

The Beneteau Oceanis is a popular cruising sailboat that is known for its comfort and luxury. The Oceanis has a spacious interior and can accommodate large crews, making it perfect for extended sailing trips. The boat’s sturdy design and reliable performance make it a favorite among cruising sailors.

Racing Sailboats

Racing sailboats are designed with performance in mind. These boats are usually lightweight and have a larger sail area than recreational sailboats, allowing them to reach high speeds. Racing sailboats are perfect for competitive sailors who want to push their limits and test their skills. The average speed range of racing sailboats is 20-30 knots (23-35 mph).

The Melges 24 is a popular racing sailboat that is known for its speed and agility. The Melges 24 is a one-design boat that is used in numerous regattas and championships around the world. The boat’s lightweight design and high-tech features make it a favorite among competitive sailors.

How to Increase Your Sailboat’s Speed

There is nothing quite like the feeling of sailing at high speeds, with the wind in your hair and the sun on your face. However, achieving maximum speed on a sailboat requires more than just a favorable wind. In this article, we will explore some tips and techniques to help you increase your sailboat’s speed and performance.

Optimizing Sail Trim

Sail trim refers to the setting of the sails in the most efficient way possible to harness the wind’s power and produce maximum speed. Proper sail trim can also improve the boat’s stability and balance. Optimizing sail trim involves adjusting the sails to the correct shape, angle, and tension.

One way to achieve the correct sail trim is to use telltales, which are small pieces of yarn or ribbon attached to the sail. By observing the telltales, you can adjust the sail’s position to achieve the optimal angle and tension. It is also essential to adjust the sails according to the wind conditions. For example, in light winds, the sails should be fuller, while in strong winds, the sails should be flatter.

Balancing the Boat

A balanced boat helps the sailboat move smoothly and efficiently through the water. Balancing the boat involves shifting the crew to counterbalance the forces applied on the sailboat, such as wind gusts and waves. Proper weight positioning can reduce drag and maximize boat performance.

When sailing upwind, it is essential to keep the weight forward to prevent the boat from heeling too much. Conversely, when sailing downwind, it is best to keep the weight aft to prevent the bow from digging into the water. Additionally, it is crucial to keep the weight evenly distributed from side to side to maintain the boat’s balance.

Reducing Drag

Drag is the resistance a sailboat encounters as it moves through the water. Reducing drag can increase speed potential. Techniques to reduce drag include using smooth hull coatings, eliminating unnecessary weight, and keeping the boat clean and free of barnacles and other marine growth.

Another way to reduce drag is to minimize the amount of exposed surface area on the boat. This can be achieved by using a smaller headsail or reefing the mainsail in heavy winds. It is also important to keep the sails properly trimmed, as a poorly trimmed sail can create unnecessary drag.

Proper Maintenance

A well-maintained sailboat operates at its full potential and can achieve higher speeds. Proper maintenance involves regular cleaning, lubrication, and replacement of worn-out parts. It is also essential to keep the sails and rigging in good condition.

Inspect the sails regularly for any signs of wear and tear, such as frayed edges or holes. Replace any damaged sails promptly. Similarly, inspect the rigging for any signs of corrosion or damage. Lubricate the moving parts regularly to ensure smooth operation. Finally, keep the boat clean and free of debris to reduce drag and improve performance.

By following these tips and techniques, you can increase your sailboat’s speed and performance, and enjoy the thrill of sailing to the fullest.

Sailboat Top Speeds

Speed records for different sailboat types.

Sailboats have achieved incredible speeds over the years, with some breaking speed records. The Sailrocket 2 holds the world speed record for sailing at 68 mph. The Vestas Sailrocket 2 is a hydrofoil sailboat that uses advanced technologies to slice through the water at high speeds.

Another sailboat that has broken speed records is the Macquarie Innovation. This sailboat was designed to reach high speeds and broke the world sailing speed record in 2009 by reaching a speed of 50.7 knots (about 58 mph). The boat was built with high-tech materials and was designed to reduce drag and increase speed.

Factors Affecting Top Speed

Top speed is the fastest that a sailboat can travel and is influenced by several factors. These factors include wind speed, boat size and weight, sail area, and water conditions. In most cases, the larger the sail area, the faster the boat can go, and wind direction plays an essential role in achieving top speeds.

The weight of the boat can also affect its top speed. A lighter boat can move faster through the water and is easier to maneuver. Sailboats with hydrofoils, like the Sailrocket 2, can lift out of the water, reducing drag and allowing for faster speeds.

Pushing Your Sailboat to Its Limits

Pushing your sailboat to its limits requires experience, knowledge, and skill. It involves maximizing boat speed in various wind and water conditions while staying safe and in control. Before attempting to push your boat to its highest speeds, ensure that your boat is in top shape, and you have all the necessary safety equipment.

It’s also important to understand the wind and water conditions you’ll be sailing in. Wind direction and strength can greatly affect your boat’s speed, and understanding how to use the wind to your advantage is essential for achieving top speeds. Additionally, water conditions can affect your boat’s speed, with choppy water slowing you down and calm water allowing for faster speeds.

Finally, it’s important to practice and build up your skills before attempting to push your sailboat to its limits. Start by sailing in calmer waters and gradually work your way up to more challenging conditions. With practice and experience, you’ll be able to maximize your boat’s speed and push it to its highest limits.

Sailboat speed is influenced by several factors, including wind speed, sail area, boat size and weight, and water friction. The average speed range for different sailboat types varies and depends on boat design. You can increase your sailboat speed by optimizing sail trim, balancing the boat, reducing drag, and proper maintenance. Top speeds are influenced by wind conditions, sail area, boat size and weight, and water conditions. Pushing your sailboat to its limit requires experience, knowledge, and skill, and always remember to prioritize safety.

Sailboat FAQS

How fast can a 40 ft sailboat go.

A 40-foot sailboat can typically go around 8-12 knots (9-14 mph), depending on wind conditions and the specific design and condition of the sailboat. Speed can be influenced by factors such as hull design, sail area, and weight.

How fast can a 100 foot sailboat go?

A 100-foot sailboat can reach speeds of around 12-16 knots (14-18 mph), depending on factors like the sail area, hull design, and the wind conditions. However, larger sailboats often prioritize comfort and stability over speed, so they might not be as fast as some smaller, performance-oriented sailboats.

How far can a sailboat travel in a day?

This largely depends on the speed of the sailboat and the conditions in which it is sailing. However, if a sailboat maintains an average speed of 6 knots (around 7 mph), it can travel approximately 144 nautical miles in a day of 24 hours. Please note this is a rough estimation and actual mileage can vary significantly based on numerous factors.

What is a comfortable sailing speed?

A comfortable sailing speed is subjective and can vary depending on the type of sailboat and the conditions. However, for many cruising sailboats, a speed of 5-8 knots (6-9 mph) can be comfortable. This speed allows for a good balance of progress and safety, while keeping the ride relatively smooth and the boat easy to control.

Can one person sail a 35-foot sailboat?

Yes, a 35-foot sailboat can be handled by a single person, given that they have sufficient sailing experience and the boat is rigged for single-handed sailing. However, it’s crucial to note that single-handed sailing involves a higher level of risk and requires extensive experience and skills. It’s also important to have an autopilot system or self-steering gear on board to aid in maneuvering and navigation.

Can one person sail a 50-foot sailboat?

Sailing a 50-foot sailboat single-handed is possible, but it is considerably more challenging and requires a high level of experience and expertise. The size and weight of the boat can make maneuvers like docking and anchoring quite difficult for a single person. Additionally, the boat should be well-equipped with an autopilot system and other equipment designed for single-handed sailing. It’s always recommended to have additional crew members on larger boats for safety and assistance.

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:

Table of Contents

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.

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.

What is the Average Speed of a Sailboat?

Published by oceanwave on august 29, 2023.

In addition to enjoying being on the sea, sailing also involves learning the craft of sailboat speed . Sailors need to have a solid grasp of average boat speed whether they are sailing at a leisurely pace or competing in races. We’ll delve into the world of sailboat speed in this guide, learning about what it is, how it’s calculated, and the different elements that affect it.

Recognizing boat speed In the context of sailing, boat speed describes how quickly a sailing boat is moving through the water. Sailors use it as a key indicator to assess their performance and decide on their course when out on the ocean. Typically, specialized equipment like knot meters or GPS units is used to measure boat speed. Boat speed is most frequently expressed in knots, where one knot equals one nautical mile per hour.

Factors Influencing Sailboat Speed 

Sailors who want to succeed in the realm of sailboat speed must learn how to maximize their boat’s design and trim while utilizing the wind’s energy. Perfecting the balance between these elements is a skill that calls for training, experience, and a thorough knowledge of sailing dynamics.

Every sailor embarks on a lifelong adventure to master boat speed, whether they plan to cruise leisurely or attempt to shatter world sailing speed records. In the end, the excitement of the voyage itself—driven by the wind and the sailor’s skill—is more important than the final destination.

Wind Direction and Speed

The wind is what propels a sailboat’s speed. The wind’s speed and direction in relation to the boat are the main factors. To maximize speed, sailors frequently seek out the best point of sail or angle to the wind.

Hull Shape and Boat Design

A sailboat’s design greatly affects its speed. How well a boat navigates the water is influenced by things like hull shape, keel type, and weight distribution. High-performance racing sailboats have streamlined hulls and little underwater drag since they are built for speed.

Sail Area and Sail Trim

The overall surface area of a boat’s sails is referred to as the sail area. For effective wind power capture, the trim, angle, and tension of the sails must be adjusted. Sail trimming correctly ensures that the sails produce the most lift and propulsion.

Water Conditions

Waves and currents in the water can help or hinder a sailboat’s progress. Strong opposing currents can slow a boat down, while favorable currents might give it an extra lift. Choppy waves may also increase resistance, which would reduce speed.

Calculating Average Speed

When sailing, calculating sailboat’s average speed is crucial for assessing its performance and for making decisions while at sea. Finding the speed at which your boat has traveled over a certain distance is a simple operation. Let’s get into the specifics of an accurate average speed calculation.

The Basic Calculation

The distance traveled and the time required to cover that distance are the two key pieces of information needed to determine average speed. Calculating average speed is as follows:

Average Speed (in knots) = Distance Traveled (in nautical miles) / Time Taken (in hours)

Your average speed, for instance, would be: If you’ve sailed 60 nautical miles in 6 hours.

Average Speed = 60 NM / 6 hours = 10 knots

This equation yields an easy-to-understand average speed, but it’s crucial to realize that your boat’s speed can change based on the wind, sail trim, and other variables.

Using GPS and Navigation Instruments

GPS (Global Positioning System) and navigational tools have greatly improved the accuracy of estimating average speed in modern sailing. The majority of sailboats have GPS systems that can automatically determine your boat’s speed and track its whereabouts.

Record the starting location, turn on your GPS, sail the desired course, and then check the GPS data to see how far you went and how long it took. You can calculate your average speed accurately with the help of the GPS.

Real-World Case Studies

Sailboat types and average speeds.

Depending on the sailboat’s kind and intended use, average speeds can vary greatly. For instance:

• The average speed of a cruising sailboat is normally between 5 and 8 knots.
• Racing sailboats are built for speed and have top speeds of at least 8 to 12 knots.
• Catamarans , which are renowned for their speed and stability, are readily capable of traveling at average speeds of 10 to 15 knots.

Sailing Conditions and Their Impact

Average speed is significantly influenced by sailing conditions:

• Light Winds: Sailboats may find it difficult to maintain greater average speeds in light wind (5 knots or less), which are typically between 3 and 5 knots.
• Heavy Winds: Sailboats can travel at substantially higher average speeds, often exceeding 15 knots or more, when strong winds (20 knots or more) are present.
• Upwind vs. Downwind: When sailing upwind (against the wind), average speeds are often slower than when sailing downwind (with the wind at your back).

It’s critical to remember that these are only general recommendations and that each sailboat may behave differently depending on its design, rigging, and crew’s level of experience.

Knowing and comprehending your sailboat’s average speed is helpful for longer voyage planning and arrival time estimation in addition to racing. You’ll gain a sharp understanding of your boat’s capabilities and how to maximize its speed under various circumstances as you practice and gain experience.

Strategies for Increasing Speed

Sailors are constantly looking for ways to increase the speed of their sailboats, whether it is for recreational cruising or competitive racing. Here are some helpful tips to assist you in improving the performance of your sailboat:

Master Sail Trim

For your boat to move as quickly as possible, proper sail trim is essential. To capture the most wind without adding too much drag, adjust your sails. Important factors include:

• Main and Jib Trim: Maintaining the optimal shape for the prevailing wind conditions requires proper trimming of your mainsail and jib.
• Twist Control: To optimize the performance of your sails, add a twist to them. When sailing upwind, the twist should be decreased, and when sailing downwind, the twist should be increased.
• Telltales: Pay attention to your sails’ telltales. They give you immediate input on airflow and aid in making accurate trim adjustments.

Weight Distribution

On a sailboat, proper weight distribution can have a big impact on stability and speed. Spread out the weight of the crew equally, and if necessary, think about moving equipment or ballast. To avoid excessive heeling (leaning) or pitching, which might make you go slower, balance your boat.

Crew Coordination

For your workforce to move as quickly as possible, coordination and effective communication are essential. To reduce errors and improve boat handling, assign roles and duties and practice maneuvers. Maintaining speed requires fluid sail adjustments, gybes, and tacks.

Optimize Sail Plan

Choose the appropriate sails for the conditions. For illustration:

• Using a Spinnaker: In downwind circumstances, deploying a spinnaker or gennaker can significantly increase speed.
• Reefing: To maintain control and avoid excessive heeling in severe winds, think about reefing (lowering sail area).

Advanced Tactics

For competitive racing or advanced sailors, consider these tactics:

• Sailing Angles: To determine the fastest course, try out various sailing angles. Instead of sailing directly upwind or downwind, this frequently entails sailing at a little angle to the wind.
• Current and Tidal Strategy: Recognise how currents and tides affect the speed of your boat. When navigating, take advantage of them.
• Weather Awareness: Be aware of how the weather is changing and modify your strategies as necessary. Take advantage of pressure changes and wind shifts to your advantage.

Understanding and maximizing your sailboat’s speed is an ongoing and gratifying quest in the world of sailing. To sum up:

• Average Speed is a crucial sailing indicator that aids in performance evaluation and enhancement.
• The speed of your sailboat is influenced by a number of variables, including the boat’s design, hull shape, sail area, and weather.
• Using a GPS or other conventional techniques, determine your boat’s speed, then use the following formula to calculate speed: Distance Travelled (in Nautical Miles) / Time Taken (in Hours) = Average Speed (in Knots).
• Varying sailboat designs and environmental factors result in varying average speeds.
• Be a master of sail trim, make the most of weight distribution, organize your crew, select the ideal sail plan, and take into account cutting-edge tactics for competitive racing.

In the end, sailing is enjoyable because you’ve mastered the skill of effectively using the wind to move your sailboat. To attain faster and more thrilling sailing experiences, embrace the learning process, adjust to changing conditions, and keep improving your skills.

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 . 

Featured Boat Care Product

Check Price on Amazon  - Better Boat Fabric Waterproof spray protects Bimini tops, canvas, upholstery and nylon from the inevitable spray of water. You can even use it on shoes, bags, luggage and car covers. 

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.

What is the Average Speed of a Sailboat?

If a car driver uses ‘cruise’ to control a car, the vehicle will achieve its maximum performance efficiency. To do something similar for a sailing boat, you would need to calculate the hull speed. This will give you the average speed that suits the type of craft you are sailing. That’s why you need to know how to work out the average speed of a sailboat.

What is a Sailboat?

It’s a boat that primarily uses wind to propel it forward. There are other factors, such as tidal direction and design of the boat, that also help to move a sailboat. For the wind direction, a sailboat uses sails instead of an engine. Although some sailboats are also fitted with small engines to help with docking, among other things.

__________________________________________________________________________

How Do You Calculate a Journey?

In the 15 century, Columbus’s Caravels sailed across the Atlantic at an average of 8 knots . We haven’t moved on much at today’s average speed of a large schooner, which is around 10-12 knots.

Remember that 1 knot is about 1.15 mph.

Sailing a boat is a challenge and takes skill to start, and significant talent to excel at, with specially built racing yachts achieving much faster speeds. A large schooner can cover up to 200 miles a day, but the speed will depend on a few important factors. See our article on how long to sail 100 miles for more information.

For top speeds sailing boats rely on the ocean current and the wind. It takes time and patience to plan for both of these factors to flow in the direction you want to sail. 

The initial calculation for a long journey can be made with a simple calculation. 

• How many miles you are going?
• Divided into how much time you want to take to complete the journey. 

But, for a sailing boat, whether that calculation is ‘do-able’ will depend on three very important factors: 

• The length of the sailing boat.
• The type of hull.
• The wind speeds. 

These three factors are vital in calculating the average speed of a sailing boat .

Why Does Length of the Sailing Boat Matter?

Generally, the longer the boat, the faster it can cut through the water. A large boat is considered to be over 50ft long. For instance:

• A 16-foot boat can move up to 5 knots per hour. 
• 50 ft boat can move up to 7 knots per hour. 
• 244ft boat can move up to 16 knots per hour. 

Showing that size makes quite a difference to speed when it comes to sailing boats.

What are the Two Main Types of Hull That Affect Speed?

There are two main types of hull, that play a major role in the speed of a sailing boat. 

A ‘mono-hull ‘is used in an everyday sailing boat. You may also hear it called a ‘displacement hull.’ It’s also a single hull and is placed under the water. This type of hull pushes the water away from the boat, so the craft can move smoothly as it cuts through the waves. 

To move faster, the hull needs to above the water level. This is also known as a ‘planing hull.’ The situation of this hull makes the craft quite buoyant, so it’s less stable. That’s why a sailing boat with a planing hull needs more than one hull, which is known as a multi-hull. Catamarans are common multi-hulled sailing boats. You may find pontoon boats as well as others that fit this category as well.

These are the favorable hulls for racing boats.

What Does Wind Power Mean?

One benefit of using wind to power your craft is the beauty of how you can utilize nature instead of an oily engine. Going faster with wind power means it will not harm the craft in any way if it’s done right. 

There are a ton of variables that go into the average speed of a sailing vessel, including the wind and water condition, the skill of the sailors, the type of boat, etc. But we can give some general ideas using the following estimations.

To calculate the average hull speed of a monohull, the length of the boat is the most important factor. When we talk about the length of the boat, it is the waterline length (LWL) that matters, and not the overall length (LOA).

The LWL is the part of the boat that sits at the waterline level. Also, note that the LWL is always less than the LOA. 

What is the Scientific Calculation for the Average Speed of a Sailboat?

This is where you’ll need that scientific calculator so you can work out the square root of the LWL. 

Let’s take a boat of 35ft in over length (LOA). 

It’s LWL, from bow to stern and not including the rudder, will be approx. 28ft. 

First, calculate the square root of the LWL, which for 28ft is 5.3 (rounded) 

Next, multiply the square root of 5.3, by 1.34. (This is the accepted scientific measurement of the wave crest between the bow and the stern. The wave crest creates the bow wave in the wake of the boat). 

Our calculation now looks like this:

5.3 x 1.34 = 7.09 

Resulting in:

The average speed of a 35ft (LOA) sailing boat is 7 knots.

Here’s the same calculation for a 15ft (LWL) 

Square root of 15 = 3.9 (rounded). 

1.34 x 3.9 = 5.189 which gives us 5.2 knots. (rounded).

To increase speed, you would need to learn how to harness the wind and the tide in your favor.

Speed, for many, can be a real adrenalin hit. The present world record speed for a sailing boat was achieved in 2012 at 68 knots (78mph).

Whereas, the average speed of a high-end racing sailboat is around 15 knots (17mph). This type of sailboat tends to be lighter. Plus, it will most likely have a double, or even triple (tri), hull, hence the planning effect. 

But a cruising sailboat tends to go at an average of 5 -8 knots.

The longer the sailboat, then the larger the crest wave. This results in it moving forward at a bigger distance than a smaller boat creating a smaller crest wave.

The shape of the hull also affects the speed. Imagine a fat-tub of a hull to a boat; it’s going to move much slower than a slimline hull, even if they’re equal in length. Design plays an integral role in speed. 

Plus, regular maintenance of your sailing boat too. This also helps to ensure its efficiency to reach top speeds. Sails must remain intact with no tears or holes and be properly tensioned. The mast must be solid. The skill of the sailor is also an essential element in achieving top speeds for a boat. Only a skilled sailor can take advantage of the winds and tide.

What is the Average Speed of a Sailboat? ANSWERED: Measurement, Hulls & Speed Factors

Sailboats are not the best choice of transportation when speed is an essential factor. The average speed of the typical monohull sailboat is between six and ten knots. Of course, many factors affect this speed, and some boats are designed to be faster than others. And of course, there are always exceptions to the rule, and some of today’s fastest racing sailboats can fly along at speeds over 50 knots!

Table of Contents

Measuring boat speed – what’s a knot, types of boat hulls, how do you calculate displacement hull speed, factors affecting the speed of a sailboat, ways to design a faster sailboat, knots and nautical miles.

The speed of boats and ships is measured in knots or “nautical miles per hour.” This is slightly different than the standard MPH you may use in your car. For example, a nautical mile (nm) equals 6,076 feet, whereas a statute mile is equal to 5,280 feet. So one nautical mile is equivalent to 1.15 statute miles. 

Why do boats use nautical miles? The nautical mile is born from the lines of latitude (also called parallels) drawn across the globe by map makers. Each degree of latitude is the same distance from the next one. Each degree contains 60 minutes, and each minute is exactly equal to one nautical mile.

VMG vs. SOG

Finally, it’s also important to realize that there are many ways to measure the velocity of a boat through the water. The simplest method is to use what is commonly called a knot log. In the old days, this was a calibrated string that trailed behind the boat. It was marked by (you guessed it) knots in the string. You let out the string, and the faster the boat was traveling, the more knots passed over the side. So, by counting the knots over a specific time, say ten seconds, you could estimate boat speed through the water. 

Today, boats don’t typically carry knot logs. Instead, the modern equivalent is an electrical instrument with a spinning water wheel mounted in the hull. The tiny wheel spins faster as the boat travels faster and it sends the boat’s speed to the instruments. 

GPS also provides speed information by telling the captain their SOG (speed over the ground) and VMG (velocity made good). Speed over ground is usually about the same as the boat speed measured by the water wheel – except that SOG is measured across the earth’s surface. So if the boat is being affected by a 2-knot current in the opposite direction, the boat speed may indicate 6 knots while the SOG will show 4 knots. 

SOG is the most important speed for calculating trips because it is the actual speed you’re moving to get to Point B. Another way to describe this is VMG (velocity made good). This is the amount of your total speed that is getting you to your next waypoint or destination. If you’re tacking into the wind and not headed directly towards the finish line, your VMG will be significantly less than your SOG. 

There are three main types of boat hull – displacement, semi-displacement, and planing. 

Displacement

Displacement hulled vessels sit down low in the water. This is the classic ship—it just pushes the water out of the way to get where it’s going.

Displacement hulled vessels are limited in the speed at which they can travel. The faster they travel, the larger the bow wave they push up in front of them. The water is pushed up at the bow and then again at the stern. The difference between the bow and the stern waves creates a suction that only increases as power increases. That means that it’s very hard under most circumstances to go any faster.

This concept is known as the hull speed of a vessel—it’s a speed limit that the vessel cannot exceed. The only want to make a boat go faster is to increase the distance between the bow wave and the stern wave—another way of saying that the only want to build a faster boat is to build a longer boat. 

Nearly all monohull sailboats have displacement hulls. A displacement hulled vessel may not move very fast, but it is very efficient and takes very little power for its given weight. 

Semi-Displacement

If a boat is designed to do it, it can be pushed fast enough to sit up on top of its bow wave. It’s still sitting low in the water, but it can surf that wave just a little and break the stern wave’s suction. This takes an awful lot of power—more than most sailboats can muster—but it is commonly used in large trawlers and powerboats.

Finally, if a boat has a sleek, flat-bottomed hull and enough power, it can blast over the top of the bow wave and ride on top of the water. This is what go-fast boats and many fishing boats do, along with high-powered dinghies and ski boats. 

It takes an enormous amount of power to get a boat on plane, and the amount of power goes up as the vessel’s weight goes up.

The formula for figuring out the hull speed of a displacement hull in knots is 1.34 times the square root of the vessel’s waterline length in feet – or HS=1.34*√LWL.

If math isn’t your thing, here’s an online calculator . If you crunch some numbers, here are some examples you might come up with. 

• 20 feet LWL, 6.9 knots
• 30 feet LWL, 8.4 knots
• 40 feet LWL, 9.8 knots
• 50 feet LWL, 10.9 knots
• 60 feet LWL, 11.9 knots

It is important to remember that the length at the waterline (LWL) is typically less than the length overall (LOA). Therefore, if a vessel has long overhangs, waterline length is reduced. 

For the typical monohull sailboat, the hull speed represents the upper end of its performance. But there are plenty of other factors, and getting up to the speed happens much faster for some vessels than it does for others.

Amount of Wind

If a sailboat is trying to sail, but there is no wind—there’s very little chance of it getting to its hull speed. So one of the most significant factors affecting how quick a sailboat is is how well it sails in “light airs.” 

Most cruising sailboats can’t get up to their hull speed until the wind is at a steady 12 to 15 knots. As a general rule of thumb, most of these boats move at roughly half the true wind speed. So a wind of 15 knots moves a boat at about 7.5 knots, and if the wind is only 7 knots, it can typically only make 3.5 knots.

Point of Sail

Even then, they can only do it at certain points of sail. Most boats’ fastest point of sail is when the wind is “on the beam” or coming from the side. This is the most efficient aerodynamically for the sails to work. Sailing dead downwind is one of the least efficient.

Type of Sail Being Flown

Sailing in light winds requires light wind sails. These are typically larger than the boat’s regular cruising sails and made from lighter, more efficient fabric. 

Most people are familiar with the spinnaker used for downwind sailing. These large and colorful sails are built out of lightweight material so that a light wind can fill them easily. They can be huge, enough to move a heavy boat in light winds. There are also Code Zeros and gennakers, each of which is a different type of light air sail designed to help boats go faster on calm days.

These sails don’t make the boat go faster, per se. Because they’re built light, you can’t safely fly them with an apparent wind speed over about 15 knots. So what they do is allow a boat to sail when there isn’t enough wind for their regular sails to work.

Amount of Drag

Skin-friction drag comes from the water flowing over the hull. If the bottom of a boat is allowed to become fouled with barnacles and marine growth, it will create more drag. That means that it will be slower than a boat with a perfectly smooth bottom. 

There are also other sources of drag to think about. For example, many sailors replace their standard propellers with feathering or folding ones, which produce less drag while sailing.

Rough seas are a fast boat’s worst enemy. The action of pounding through lump seas causes the boat’s speed to stop and start, and as a result, it will have difficulty maintaining a fast speed. In these cases, the average speed is used for planning purposes because the speed climbing “uphill” will be slow while the speed surfing down waves will be ridiculously fast. 

We already know that one way to go faster is to buy a longer boat. So how else can the speed of a boat be made faster? Here are three ways.

Modern Hull Designs

Old-school designs typically had larger underwater profiles like full-keel designs. Compared to modern race-inspired boats, which feature spade rudders and deep fin keels, the shape of these boats creates much more drag. The result is that modern designs sail faster in light winds. 

Another factor that affects the speed of a boat is the shape of the hull itself, not just the keel. The deeper a hull is, the harder it is to get it to push over the bow wave, even a little bit. As a result, a flat and shallow bottomed sailboat can surf down waves and skip over its bow wave, given enough wind. 

It’s this simple design philosophy that has so affected cruising sailboat design over the last few decades. As a result, most cruising boats have become mirrors of racing boats from years past—round, flat bottoms and fin keels. 

Most cruising multihulls are displacement hulls like monohull sailboats, yet they can often sail much faster than their hull speeds. Why? They take advantage of a tiny loophole in the rules.

Multihulls use very narrow hulls, which can often cruise at speeds much faster than your standard displacement hull. For example, a catamaran can usually sail 20 or 30 percent faster than a monohull of the same size. 

Catamarans and trimarans also go fast by being lightweight. It takes less power to move a lighter object, so they can move much faster in light winds by keeping these boats light. In addition, multihulls do not require lead or iron ballast for stability as monohulls do. 

If built for performance, their structures and hulls are commonly made from high-tech materials like carbon fiber. Where monohull cruisers load their boats down with gear and supplies, multihull owners are typically much more careful about the weight they carry on board if they want to maintain their speed advantage.

Foiling Sailboats

The latest trend in the world of sailboat racing is the foil. These boats, both monohulls and multihulls, use underwater wings called hydrofoils to raise the hulls completely out of the water. Once “flying” on the foil, they are no longer bound by standard boating physics. 

For example, in the 2020 America’s Cup yacht races, foiling monohulls were used. The AC75 Class race boats are 75 feet long and able to reach speeds of over 50 knots. These new technologies make it possible to sail at up to three times the true wind speed. 

Matt has been boating around Florida for over 25 years in everything from small powerboats to large cruising catamarans. He currently lives aboard a 38-foot Cabo Rico sailboat with his wife Lucy and adventure dog Chelsea. Together, they cruise between winters in The Bahamas and summers in the Chesapeake Bay.

Average Speed of a Sailboat (How Fast Can a Sailboat Go?)

Written by Anthony Roberts / Fact checked by Jonathan Larson

You might have seen how sailing yachts seem to outpace motorized boats in a regatta, prompting you to ask about the average speed of a sailboat. Although the record holder (the Vestas Sailrocket 2) can blitz to 65.5 knots, the run-off-the-mill sailing vessel can only reach four to six knots.

Several factors influence sailboat speeds, and we will examine each in this article. Please keep reading, so you will not miss the invaluable information you will get from this post.

Table of Contents

1. Hull shape

2. sailboat length, 1. alternative measurement, 2. converting knots to kph or mph, 1. hull type, tips to improve speed, frequently asked questions, how fast can a sailing vessel go.

Regatta-competing racing sailboats can reach a top speed of about 20 knots, while custom-built high speed racing yachts can log 50 knots. As mentioned, the Vestas Sailrocket 2 blitzes the waters at a dizzying 65.5 knots (75.38 miles per hour or 121.31 kilometers per hour).

On the other hand, the average sailboat in lakes and other bodies of water can only top the speed charts at seven knots (8.06 MPH or 12.97 KPH), averaging about four to six knots (4.6 to 6.9 MPH or 7.4 to 11.1 KPH).

An 1800s or 1970s sailing ship (i.e., galleon or clipper) has about the same speed as the average modern sailboat. However, it is worth noting that the Sovereign of the Seas logged the highest velocity for a sail-powered ship at 22 knots (25.32 MPH or 40.75 KPH) in 1854.

Meanwhile, the fastest sailing dinghy is the International Moth, blasting the waters at 35.9 knots (41.3 MPH or 66.5 KPH).

So, why the variance?

Two intrinsic (within the boat itself) factors impact the speed of sailboat units. These include hull shape and vessel length.

Racing sailboats are faster than cruising yachts because of their unique hull shape differences.

A sailboat built for speed has a super-slim hull and straight buttock lines. The aft section forms a straight line between the slightly wide transom and the hull’s lowest point.

Meanwhile, sluggish sailboats have a “fat tub” hull shape, a narrow stern, and a curvy hull.

There is a scientific explanation about the impact of sailboat size (or length) on its speed. Sailing vessels create a wave pattern as they move along the water, one at the front and another at the back.

A water wave sufficient to help the boat move occurs if the sailboat’s length is similar to the length of the wave. This phenomenon “lifts” the vessel’s bow, increasing its speed while reducing water resistance.

Hence, a longer sailboat will have a greater cruising speed than short vessels because they can create longer waves.

We prepared the following table to illustrate how vessel length impacts sailboat speed. Hence, a 40 ft. sailboat will always be speedier than shorter sailing vessels (<40 feet).

How to Calculate the Speed

You can use an online sailboat speed calculator, input the required variables, and the system will automatically run the equation. Alternatively, you can determine your sailboat’s average speed by following this simple formula.

Average yacht speed knots = (√(LWL))x 1.34

In which “LWL” is your sailboat’s length at the waterline

Suppose you have a 36-foot sailboat that measures 26 feet at the waterline. The square root of 26 is 5.099. Multiplying this number by 1.34 will result in 6.832 or 6.8 knots.

How about a 59-foot sailing vessel with a waterline length of 47 feet? The square root of 47 is 6.86. We will get 9.19 knots after multiplying 6.86 by 1.34.

Please note that this sailboat speed is the average, provided you have clear skies, calm seas, and an ideal sailboat setup.

For example, suppose we achieved 6.8 knots with 15-knot winds and a sail setup of 50- to 120-degree true wind angle. We can expect our sailboat example to be slower if we do not achieve these conditions.

You can also determine your sailboat’s speed by sailing from one point to another. However, you might have to ascertain the distance between these two locations beforehand, and it should be in nautical miles (NM).

Why nautical miles? We are measuring sailboat speeds in knots. One knot is equivalent to one NM per hour. It is worth noting that one NM is 1.15 land-based miles, to put it in perspective.

Take the known distance between the two locations (in nautical miles) and divide the number by the time it took you to complete the journey.

For example, suppose you sailed from Buffalo, New York to Detroit, Michigan, with a distance of 186.99 nautical miles, and it took you 23 hours to complete the journey. In that case, 186.99 divided by 23 hours is 8.13 knots.

You can also take your average sailing distance per day to gain a more comprehensive understanding of your sailboat’s speed. For example, a sailboat with a 6-knot average speed can cover 144 nautical miles in 24 hours (6 x 24 = 144).

Something might be amiss if your boat sailed for 24 hours and covered less than 144 nautical miles. You might have more favorable sailing conditions if you traveled the distance in less than 24 hours.

Sailors use “knots” as the unit of measure for vessel speed. Unfortunately, ordinary mortals are unfamiliar with this metric. They are more in tune with “miles per hour” (MPH) or “kilometers per hour” (km/h or KPH).

We mentioned that a nautical mile is slightly longer than a land-measured mile (1.15 statute miles). We also know that 1 NM per hour is 1 knot. Hence, we can multiply the “knot” value by 1.15 to determine your sailboat’s speed in MPH (miles per hour).

A mile is also longer than a kilometer (1 mile = 1.60934 kilometers). Thus, we can assume our KPH values will be higher than knots and MPH. We can multiply “knots” by 1.852 to get the value in KPH.

For example, a top speed sailboat blitzing at 50 knots has a maximum velocity of 57.5 MPH (50 knots x 1.15) or 92.6 KPH (50 knots x 1.852).

On the other hand, a 6.5-knot sailboat can only muster 7.475 MPH or 12.038 KPH.

Factors Affecting Sailboat Speed

Although we already discussed hull shape and vessel length’s influence on sailboat speed, three other factors can impact watercraft velocity.

Sailboats with at least two hulls (catamarans) are 25 to 30 percent faster than monohulls, given equal lengths.

Hence, if a single-hulled sailboat can go six knots, we can expect a catamaran to have an average speed of 7.5 to 7.8 knots (8.625 to 8.97 MPH or 13.89 to 14.45 KPH). This sailboat hull can match a racing monohull sailboat’s velocity with better comfort.

Add another hull to the catamaran (a trimaran), and you can outpace a racing monohull by doubling its velocity.

Although some sailboats have engines, most rely on wind power for propulsion. Hence, stronger winds can make a sailboat go faster by pushing against the sail. Unfortunately, wind direction can also influence vessel speed. You can go fast if the wind blows in your heading.

You might be inclined to believe that calm waters can make your sailboat go faster. Unfortunately, serene waters often mean gentle winds. And if there is not much wind to push the sail, you cannot expect your vessel to go faster.

Current, wind, and wave or sea condition is the most important factor in determining a safe vessel speed. If the water is rough, it is safer to reduce speed because bad weather can impair visibility and make it challenging to maneuver the vessel.

Here are some tips to improve sailboat speed.

• Ensure the sailboat’s proper operating condition, especially the mast, sail, and extrusions. Check the hull and foils.
• Be mindful of the sailboat’s maximum weight capacity, ensuring you do not exceed the rating. Moreover, the correct weight distribution can help you pilot the sailboat faster.
• You might want to brush up on your sailing competencies, including sail control, steering, sail angling, genoa and jib control, kite curling, efficient pumping, and wind positioning.
• Check your sailboat’s settings, including the shroud tension, mast rake, jib car position, mast step position, keel position, and vang tension.

Sailboat speed vs wind speed: which’s faster?

A vessel sailing faster than the wind is possible with a superiorly designed and streamlined hull and the correct sail angle. Otherwise, the sailboat will only be as fast as the wind speed on the sail.

It is also worth mentioning that sailboats with multiple hulls or a planing hull can be faster than wind speeds.

How fast can a sailboat go under power?

A sailboat under power can move on the water at an average velocity of four to five knots (nautical miles per hour) or 5 MPH (8 KPH). This is not very fast but not slow either.

Are catamarans or monohulls faster?

Multihulls (i.e., catamarans and trimarans) are faster than monohulls, averaging about nine to ten knots (10.35 to 11.5 MPH or 16.69 to 18.52 KPH). On the other hand, monohulls only average six to eight knots (6.9 to 9.2 MPH or 11.11 to 14.82 KPH).

The average speed of a sailboat varies across sailing vessel types, sailboat lengths, hull shapes, and hull types. Wind and waves can also influence sailboat velocity.

Given ideal weather conditions, the average sailing vessel can cruise at four to six knots. Custom-built, high-performance racing yachts can blitz the waters at up to 65 knots. Twin-hulled sailboats are 25 to 30 percent faster than their single-hull counterparts, while triple-hulls are super-quick.

Of course, everything depends on wave and wind conditions.\

How Fast Do Catamarans Go?

Last Updated by

Daniel Wade

August 30, 2022

‍ Catamarans are known for their speed, and some vessels are fast enough to break world sailing speed records.

Catamarans can go between 15 and 30 knots, with the fastest achieving speeds well in excess of 60 knots. Sailing catamarans are sometimes twice as fast as monohulls and cut through the water with greater efficiency.

In this article, we’ll cover how fast catamarans can go based on factors such as size, sail area, and design category. Additionally, we’ll compare catamaran speeds to monohulls and trimarans and cover the reasons why multi-hull sailboats blow monohulls out of the water.

We sourced the information used in this article from sailing guides and hull speed calculations. Additionally, we sourced information directly from the manufacturers of common catamarans.

Table of contents

‍ Catamaran Speed by Type

Catamaran design can be split into different categories. After all, different vessels are designed for different tasks, as speed isn’t always the most important design consideration.

The fastest type of catamaran is the ultralight racing catamaran. These vessels have extremely narrow hulls and a remarkable planing ability. They’re designed to pierce waves and often achieve speeds in excess of 45 knots or greater, depending on conditions.

The second fastest catamaran variety is the sport catamaran. Sport catamarans often include a fairly good level of creature comforts in the cabin. They’re technically hybrid designs, because they are envisioned as a combination between a racer and a cruiser. Sport catamarans can achieve 30 knots or greater.

Cruising catamarans are designed primarily for safety and comfort. They’re often used for long offshore passages, where speed is important, but comfort is king. Despite their accommodations, cruising catamarans can still achieve a respectable 15 to 20 knots of speed—sometimes 50% faster than similarly-equipped monohulls.

Why are Catamarans So Fast?

Catamarans are remarkable vessels that can achieve amazing speeds. As a result of their unconventional design, typical calculations for hull speed (such as those used for monohulls) don’t always apply.

But what makes catamarans so much faster than equivalent monohulls? The first and most obvious speedy design element are the hulls themselves.

Catamarans don’t have a deep keel or a centerboard. This is because the second hull acts as a stabilizing device, and it helps the vessel track straight. The lack of a keel reduces weight (and equally important). It also reduces drag.

Additionally, catamarans behave in strange ways while underway. The hulls have a tendency to rise out of the water further the faster they go. This further reduces drag and makes it easier for the vessel’s speed to climb once it starts to move.

One additional characteristic is how the vessel’s sails point relative to the wind. Catamarans keep their sails perpendicular to the wind, which allows them to harness energy more efficiently. This is because, at a perpendicular angle, less wind energy is lost by spillage over the edge of the sails.

Are Catamarans Faster than Monohulls?

Yes, catamarans are typically faster than monohulls. They’re also a lot more stable, as their spaced-out hulls provide better motion comfort in rough seas. Catamaran hulls are narrower than monohulls, which also reduces drag and increases speed.

Catamaran vs. Monohull Speeds

We know that catamarans are faster than monohulls in most situations. But how much faster are they? Here’s a table of hull speeds for monohulls, which is a useful reference when comparing speed. Hull speed isn’t the absolute fastest that a boat can go, but it’s a good practical estimate for understanding the hydrodynamic limitations of single-hull designs.

Hull speed calculations for catamarans are more complicated. This is because catamarans have a greater length-to-beam ratio. And due to their narrow hulls and open center, they aren’t affected by the same hydrodynamic drag forces that monohulls are limited by.

For example, a 55-foot monohull sailboat with a waterline length has a hull speed of 9.4 knots or 10.9 mph. Its actual speed could exceed that in the right conditions, but rarely by more than a few knots.

Compare that to an efficient 51-foot catamaran, which can easily achieve speeds in excess of 20 knots in reasonable winds. That’s more than double the hull speed of a monohull with a similar waterline length and proves that catamarans operate under a completely different set of rules.

Wave Piercing

One aspect of catamaran design that makes them superior speeders is their ability to pierce waves. Specially designed catamarans have minimal buoyancy at the bow, which allows them to slice through waves instead of going over them.

This increases the speed at which catamarans can cover the distance. Think about it—a boat going over a wave has to use more energy to reach the same destination, as the height of the wave almost makes the distance further.

It’s like walking over a hill or on flat ground—you’ll take more steps walking up and down the hill than in a straight flat line. Wave piercing catamarans enjoy better stability, and they ‘take the flat road’ to a greater extent than monohulls.

Do Catamarans Plane?

Planing is when a boat’s hull rises out of the water due to hydrodynamic lift. This increases speed and efficiency, as there’s less drag but sufficient contact for stability. It also reduces rolling, as the bow only contacts the taller portions of the waves.

Catamarans have planing characteristics, but they generally don’t plane as dramatically as powerboats. This is still worth noting, as catamarans are specifically designed to use the phenomenon of hydrodynamic lift to gain speed and efficiency.

You’ll visibly notice a catamaran’s hull rising out of the water as it increases in speed. Compare that to a displacement monohull design (such as a classical cruising sailboat with a deep keel), which won’t rise out of the water in any significant way.

Are Catamarans Faster than Trimarans?

A trimaran is a catamaran with an additional hull in the center. Trimarans are usually less common than catamarans, but they have some of the same design benefits as other multi-hull sailboats.

At first glance, it would seem logical that trimarans are slower than catamarans. After all, they have an extra hull in the center, which likely increases weight and drag. However, there are more important factors at play here.

Trimarans are almost universally faster than catamarans. This has to do with weight distribution. Trimarans center their weight over the middle hull, using the outer hulls primarily for stability. This allows them to reap the benefits of a catamaran while increasing the efficiency of the wind power it captures.

Fastest Catamarans

Catamarans are popular for racing. There are several world records held by catamarans and numerous production boats with especially impressive speed-to-size ratios. Here are a few of the fastest racing and production catamarans ever built.

Fastest Sailboat Ever—Vestas Sailrocket 2

The Vestas Sailrocket is a specialized racing boat designed only for speed. This incredible vessel is actually the fastest sailboat ever built—and no wonder it’s a catamaran. A monohull simply can’t achieve record-breaking speeds when put head-to-head with a lightweight multi-hull.

The vessel, which earned the world sailboat speed record in 2012, has a modest 150 to 235 square feet of sail. Nonetheless, it managed to achieve a remarkable top speed of 65.45 knots in only 25 knots of wind. That’s about 72 miles per hour—in a sailboat.

Soon, a team of Swiss engineers will release their own version designed to beat the 65-knot speed record. Their vessel, which is a hydrofoil, will attempt to hit an incredible target speed of about 80 knots.

Outremer Catamarans

But what about production catamarans? How do they stack up, and how fast can they go? French boat builder Outremer Catamarans builds some of the fastest production catamarans ever built. These are not specialty racing boats—in fact, they’re average-sized cruising catamarans.

Let’s use the larger Outremer 51 as an example. This high-end cruising cat is known for its almost outrageous speed capabilities. In ideal conditions, owners of the Outremer 51 have reported speeds exceeding 20 knots for extended periods.

That’s a production catamaran with speeds that rival 20th-century warships. With such a fast boat, the world’s oceans start to appear a lot smaller. Plus, the genius design of the Outremer 51 allows it to be crewed by just two people.

But how do Outremer catamarans achieve such high speeds? The secret is in precise engineering and hull design, along with a sail plan that’s perfectly catered to the vessel. The hulls are sleek and narrow and designed to cut through the water with minimal drag.

From the bow, the Outremer 51 hulls look paper-thin. They increase in width gradually, which eliminates areas of sudden drag. These narrow hulls evenly distribute the vessel’s 21,825-lb displacement. Its low-buoyancy bows reduce drag and blast through waves instead of riding over them.

A Complete Guide On Average Boat Speeds (Pontoon, Sailboats, And Cruisers)

If you intend to buy a boat, or simply want to know more about the speeds of some common types of boats, then you’re in the right place.

As we will discuss during this article, the speeds of the most commonly used boats (sailboats, pontoons, and cruisers) are not going to take your breath away. But, knowing what to expect from these boats is important for any new sailor hitting the waters.

When you compare the speeds of these boats to the fastest ever recorded, well, there is no comparison. That was achieved by a speedboat in 1978. The speed? An incredible 317.8 mph or 511 km/h (276 knots).

However, that boat, the Spirit of Australia, was powered by a jet engine, rather than a standard propeller. Therefore, you’re very unlikely to see such speed records like this ever broken with propellers.

Over the years, many boats have been made to run quickly, such as rum-runners and motorboats. With some reaching speeds of 90 mph, you can be forgiven for thinking that modern boats would regularly achieve the same pace.

The truth, however, is not so exciting. Most boats these days will not reach such speeds as they do not need to outrun others as many smuggling rum-runners did.

Let’s find out more about the speeds of pontoons, sailboats, and cruisers below. We will also be looking at the factors that impact the speeds of boats, so you know what to expect out on the water.

Factors That Affect A Boat’s Speed

Before we find out the average speeds of pontoons, sailboats, and cruisers, we want to discuss what can affect how fast, or slow, they go.

The most significant factors that affect a boat’s speed tend to be its hull length and hull length. The less body a boat has in the water, the faster it is typically able to travel. And, the longer the boat’s hull, the faster it will usually go, too.

Overall, the main contributing factors to a boat’s speed are usually its length, its hull type, and the direction and speed of the wind.

Let’s start by taking a look at why the length of a boat’s hull can determine how fast it can go.

A Boat’s Length

The longer a boat, the faster it tends to go. All in all, this is the rule of thumb for just about any boat.

Below are varying lengths of boats and their maximum hull speeds, to give you a better idea:

• Length – 16 feet. Meters – 5. KMH – 9.3. MPH – 5.8. Knots – 5
• Length – 26 feet. Meters – 8. KMH – 12.6. MPH – 7.8. Knots – 6.8
• Length – 36 feet. Meters – 11. KMH – 14.8. MPH – 9.2. Knots – 8
• Length – 40 feet. Meters – 12. KMH – 15.7. MPH – 9.8. Knots – 8.5
• Length – 65 feet. Meters – 20. KMH – 20. MPH – 12.4. Knots – 10.8
• Length – 80 feet. Meters – 24. KMH – 22.2. MPH – 13.8. Knots – 12
• Length – 100 feet. Meters – 30. KMH – 24.8. MPH – 15.4. Knots – 13.4

As you can see, the formula of a longer boat being a faster boat stands up. A 100 feet boat is over twice as fast as one that is just 16 feet. The speed difference may not seem that stark, but in terms of knots, an increase from 5 to 13.4 knots is pretty dramatic.

The Type Of Hull

The hull type is also a significant determining factor in the speed of a boat. Take a sailboat, for example. If it is fitted with a displacement hull or a monohull, it will be able to reach standard speeds between 4.5 mph and 7 mph (4 to 6 knots).

If a speedboat were to use a planing hull instead, however, it will travel at much faster speeds of around 35 to 58 mph (30 to 50 knots).

This is why many sailboats can reach such speeds. Without their planing hulls, they would travel considerably slower across the water.

The Direction And Speed Of Wind

As well as a boat’s length and the type of hull it has, the speed and direction of wind have a huge impact on a boat’s average speed.

When it comes to sailboats, this is especially true, as a strong wind pushing against the sails can slow the boat down by a considerable margin.

If you are sailing the ocean (see also ‘ 6 Differences Between Sailing On The Ocean Vs. A Lake ‘) in a sailboat, the wind’s speed and direction must be taken into consideration along the journey, and before.

Traveling downwind is something you should try to aim for as often as possible when using a sailboat. Moreover, a favorable current can also help the boat travel faster.

Average Boat Speeds

Now we have taken a glimpse of the factors that can affect a boat’s speed, let’s study the average speeds of pontoons, sailboats, and cruisers below.

Here are the average speeds of these vessels:

• Pontoon – Average Speed: 15 mph to 30 mph. Top Speed: 35 mph
• Sailboat – Average Speed: 8 mph. Top Speed: 12 mph
• Cruiser – Average Speed: 16 mph to 30 mph. Top Speed: 50 mph

Pontoon Average Speed

Pontoon boats may look ideal for a relaxing escape on the water (and they are), but they can reach very fast speeds when the conditions are right.

Under certain circumstances, pontoon boats can travel at over 30 mph quite easily. If their engine is powerful and large enough, pontoons can even reach 35 mph. Take a pontoon with a 90HP motor, for example.

This will easily move at over 30 mph. Cut this motor to only 60HP and the speed is cut in half to just 15 mph.

Even with passengers weighing a pontoon down, a pontoon with a 90HP engine can reach 25 mph.

There are exceptions to the rule, however. In March 2018, Brad Rowland managed a speed of 114 mph (99 knots) in his South Bay 925CR pontoon. To this day, this remains a world record.

Sailboat Average Speed

If you want your sailboat to travel faster, you need to harness the power of the wind. In fact, this is one of the most important skills required to move a sailboat at a faster speed.

In general, the average cruising speed of a sailboat sits at around 8 mph to 12 mph. But, this wouldn’t make for very exciting races. That is why many sailboats can achieve much faster speeds.

In 2012, Paul Larsen, an Australian sailor, broke the world record for the fastest sailboat as he managed a top speed of 75 mph (65.45 knots) in his custom-built Vesta Sailrocket 2. That’s fast!

Throughout the centuries, the average speed of sailboats has remained similar.

Ships of the 15th Century, such as Christopher Columbus’ Santa Maria, had an average cruising speed of approximately 4 mph (4 knots). The top speeds of such boats were around 9 mph (8 knots).

Cruiser Average Speed

Cruisers are popular boats, owned by families throughout the U.S. AS the name suggests, these are ideal for cruising on lakes and large bodies of water, and when they travel at moderate speeds, they are capable of going over 800 miles without needing to refuel.

Don’t we wish our cars were like that? We sure do!

Cruisers vary in their build and design. Therefore, the speed of one cruiser may be different to the next.

But, in general, the slowest cruising speed for these types of boats tends to be approximately 16 mph. But, if this slower speed means you save money on refueling, you’ll be happy to travel like this at all times!

If that’s a bit too slow for you, you could try sailing a sports cruiser. These are the fastest of all cruisers, managing top speeds of about 50 mph and a cruising speed of 30 mph.

Sometimes, it’s not about how fast you go, but how long it takes you to get to a destination.

If you have a journey that is going to take a week or so, a larger motorboat is a better option. Like sports cruisers, these tend to have an average cruising speed of about 30 mph. Any slower, and journeys could take too long.

Boat Speed Laws And Regulations

Just because a boat can reach a certain speed, it doesn’t mean you can travel that quickly everywhere you go. Like on our roads, there are certain laws that you must adhere to when sailing (see also ‘ A Complete Guide On Tacking And How To Tack A Sailboat ‘).

When on the water, it’s certainly a little trickier to find out the speed limit of where you are compared to driving on the roads. As you can imagine, there are not always speed limit signs telling you the speed limit on the water.

The speed limits tend to change in waters for a variety of reasons. The time of day or night, your type of boat, the type of waterway, and many other factors can affect the speed limit.

And, unlike on our roads, the speed limit of boats is not always a specific number.

When you’re sailing on the sea or ocean’s open water, or you’re on a large lake, you can usually travel at top speeds, as long as your outlook is safe and clear ahead of you.

But, things become stricter as you get closer to the shore. When sailing in a bay or on a river, you need to be more cautious of what is around you because of the restricted area.

In such circumstances, you must look out for “No Wake Zones.” These are found in many bodies of water, especially close to the shore, marinas, docks, and in canals.

To comply with No Wake Zone rules, your boat must move slow enough to not produce a large swell that could be a danger to others around you.

These include swimmers, other sailors, and animals. Traveling through a No Wake Zone can be a little tiresome, but these restrictions are in place for the safety of you and for others.

In Conclusion

Now you know the average boat speeds of pontoons (15 mph to 30 mph), sailboats (8 mph), and cruisers (16 mph to 30 mph).

Whilst there are places to travel at faster speeds, always be aware of everything around you and stick to the laws of the water you are sailing in.

How Fast Can A Boat Go? 15 Examples of Average, Maximum, and Record Speeds!

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

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.

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.

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.

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."

How Far You Can Sail In A Day: Calculating Speed And Distance

A sailboat can travel 144 nautical miles in 24 hours with an average cruising speed of 6 knots, which is realistic for a 35-45-foot sailboat. If the average speed is reduced to 5 knots, you will cover 120 nautical miles in the same timeframe.

In this article, you’ll discover how many nautical miles you can sail at any time based on your average boat speed. You’ll also learn how to calculate boat speed and examine factors affecting your sailing journey.

UPDATE: I have included a Sailing Distance Calculator and a Hull Speed Calculator for your convenience .

How to calculate the average distance in relation to speed and time

If you are familiar with your boat and know your average cruising speed, it is easy to calculate how far you can sail at any time.

Multiply your average speed in knots with time in hours; the result will show the distance covered in nautical miles. Remember that when calculating your distance, you want to use your speed toward your destination, not your speed over the ground, especially when you are sailing angles.

This term is VMC or VMG-C: Velocity Made Good on the Course.

VMG indicates the speed of your vessel directly towards or away from the wind . VMC indicates the speed of your vessel directly toward your destination .

Your average speed toward your destination “VMC ” and speed over ground “SOG ” will only be the same when you sail directly toward your target. Most modern sailing instruments and chart plotters can show your VMC if you have plotted a route to your destination and calculate your estimated time of arrival, or ETA, based on this number.

How far you can sail in a day, half a day, and 8 hours

I made a table that shows you how far you can sail in 8, 12, and 24 hours based on average cruising speed:

How to determine your average sailing speed

If you are new to sailing and unfamiliar with your sailboat, you first want to determine what speed you can expect to sail. The best way to determine your average cruising speed is by getting to know your boat and how it performs in different weather conditions at different points of sail.

Factors Affecting Sailing Speed

While calculating the average sailing distance of a boat, it’s crucial to understand that sailing speed depends on various factors. For example, your speed will be affected when you are beating into the wind or a current.

And you don’t always want to push your boat to its limit to reach your top speed. In many situations, you may want to bear off your course to reduce the stress on the vessel, crew, and yourself. Doing so will reduce your average speed towards your destination.

There are several things that will affect your speed at sea, and I’ve listed the major ones here:

• Hull length: The longer the boat, the higher the potential maximum hull speed is because of the increased water length. Larger boats typically carry larger sails, which also increase their speed potential.
• Sail area: The sail surface area affects the boat’s speed. Larger sail areas catch more wind, resulting in higher speeds. However, larger sails can also make it more challenging to manage the boat, especially in strong winds. The sails rely on their shape to drive the vessel forward, and the shape of a sail will change as they get older, making them less effective. Learn more about types of sails here .
• Tide and currents: Sailing with the tide and using currents to your advantage will positively impact your sailing speed. Sailing into it, or beating as we call it in the sailing world, will reduce your speed.
• Weather conditions: The wind’s strength and direction are critical in determining your boat’s speed. Light winds may slow your progress, while strong winds can make for faster sailing or lead to challenging conditions that require you to reduce speed for safety. You also have to consider your point of sail and the wind speed affecting you .
• Crew experience: A skilled crew can efficiently trim sails and navigate, maximizing the boat’s performance, which translates to more nautical miles covered per day. Some vessels are even easy to sail effectively solo if the skipper knows what he is doing. However, most cruisers would rather be chasing a comfortable ride than the vessel’s maximum potential.
• Boat condition: A well-maintained boat with a clean hull, good sails, and solid rigging will perform much better and ultimately cover more distance than a neglected vessel. You’ll also have more confidence in a well-kept boat when you get to the point where you are pushing yourself and your vessel toward your limits.

When you know your boat and its behavior in the water, you can estimate the average speed by doing simple calculations.

How fast do sailboats go? Maximum hull speed explained

Most cruising sailboats (except for catamarans, trimarans, and some light racing boats) are usually displacement boats. This basically means that the boat is sailing through the water instead of surfing on top of it.

A displacement sailboat’s hull speed is the speed your boat has achieved when its created wave has the same length as the vessel’s loaded waterline length (LWL).

Many boats can exceed their hull speed, but the formula below will give us a decent number as a reference to determine a realistic cruising speed. I made a calculator to make it easier for you.

Hull Speed Calculator

Hull Speed = 1.34 * √Load Waterline Length (LWL “ft”)

LWL “ft”:

Hull Speed:

We will use my sailboat “Ellidah’s” numbers in this example. She is 41 feet overall, but the loaded waterline length (the part of the hull that touches the water) is 32,75 feet. The square root of 32,75 is 5.722. We then multiply this result with a factor of 1.34 and get approximately 7.67.

Now that we found the boat’s hull speed at just above 7.6 knots, we know she should be able to reach this speed in pleasant sailing conditions.

Note: If you don’t know your boat’s LWL, look up your specs here.

Average sailboat speed

When I plan a passage, I calculate with an average speed of around 6 knots, which is about 20% below hull speed, and I have found it to be pretty accurate.

To continue using Ellidah as a reference, she does 7.5 knots on calm seas and 15 knots of wind, sailing between 120 and 50 degrees true wind angle. The speed will reach 5.5 – 6.5 knots at lower or higher angles.

A good rule of thumb for most is that we can usually sail at half the apparent wind speed until we reach the boat’s hull speed, as long as we don’t have any strong currents or big waves working against us.

The bottom line of these examples is to consider the boat’s setup and the conditions we will be sailing in. Given decent conditions with good sails, we should be able to sail close to the boat’s hull speed in ideal conditions.

Determining abilities and comfort level

The last important factor to consider is yourself. Most experienced sailors don’t chase the highest possible speed but rather one that makes the boat balanced and comfortable in the conditions. It might, for example, be a good idea to slow down when beating into waves to prevent any equipment from breaking.

When sailing at night in reduced visibility, it is wise to sail more conservatively and reduce the sails, especially if you are sailing solo.

The bottom line is that looking at numbers online will only give you some of the tools you need to determine your speed and how far you can expect to travel with your boat in any timeframe.

To truly master the planning, you need to get out there, get your sails up, and combine your knowledge with the theory. After a while, you will be able to impress your friends with accurate estimations of speed, time, and distance.

A realistic average speed for sailboats between 30 and 50 feet

If you don’t want to bother with the calculations just yet and get out on the water as soon as possible, I made a little cheat sheet to help. I calculated the hull speed of small and big sailboats ranging from 30-50 feet and put them into a table.

Since we need to consider the factors discussed in this article, I have also subtracted 20% off the hull speed and rounded the result to give a more accurate estimate of a realistic cruising speed.

Final words

How far you can sail in a given time depends on your sailboat’s speed. How fast you can go depends on the weather conditions, the type and size of the boat, your setup, your equipment, and your capabilities and comfort.

Don’t get too obsessed with reaching your maximum speed unless you are racing. The trip might take a few extra hours when you slow things down, but you will enjoy yourself and your sailboat best when you are in control and sail conservatively, which comes with the benefit of being safer for both you and your boat.

Discover How Far You Can Sail In a Day – FAQ

How long does it take to sail 60 nautical miles.

With an average speed of 5 knots, you can expect to sail 60 nautical miles in about 12 hours. If you can increase your speed to 6 knots, it will take you 10 hours.

How long does it take to sail 100 miles?

With an average speed of 5 knots, it will take about 20 hours to sail 100 nautical miles. If you increase the speed to 6 knots, 100 nautical miles will take around 17 hours.

How fast do sailboats go?

• A sailboat between 30 and 40 feet will typically sail between 4 and 7 knots.
• A sailboat between 40 and 50 feet will typically sail between 5 and 8 knots.

How fast can a sailboat go under power?

Most modern sailboats have an engine dimensioned to power the boat up to its hull speed and basically make you able to achieve the same speed under power as under sail. There are, of course, exceptions. I wrote an article about sailing without sails that may interest you .

How do I convert speed in knots to miles per hour?

One knot equals one nautical mile per hour, which is 1.151 miles per hour. mph = knots * 1.151

What is the average speed of a 40 ft. sailboat?

The average speed of a 40 ft. sailboat is realistically about 6.5 knots in favorable conditions, depending on the type of boat, its sails, and its weight.

How far can a sailboat travel in a day?

What factors affect how far you can sail in a day.

The factors that affect how far you can sail in a day include the sailboat’s hull length, sailing speed, weather conditions, tide, and the sailing ability of yourself and the boat.

How does hull length affect the sailing distance of a boat?

Hull length plays a significant role in determining how far a sailboat can sail. Smaller sailboats with shorter hull lengths generally have lower maximum hull speeds. Larger boats with longer hull lengths can sustain higher speeds and cover many more nautical miles daily.

Can you sail downwind to cover more distance in a day?

Not necessarily. Some sailboats perform best with the wind behind the beam (downwind), such as catamarans and light semi-planing hulls. However, most displacement sailboats perform best close to a beam reach, with the wind in from the side. Besides, since you can’t change the direction of the wind, you’ll have to calculate your ideal velocity made good on the course toward your destination (VMC), depending on the conditions you are sailing in.

How fast can a sailboat typically sail?

The sailing speed of a boat depends on several factors, such as wind conditions and the boat’s design and size. A smaller vessel of around 30 feet will typically cruise at 5 knots +, depending on design. A 49-foot sailboat may cruise as high as 7 knots or higher on average, depending on its traits.

How can I determine the approximate maximum sailing distance of my boat?

To determine your boat’s approximate maximum sailing distance, you take your sailboat’s hull speed and multiply it with the time you intend to sail in hours. The result will give you your approximate maximum sailing distance for your boat in nautical miles.

How long does it take to sail a certain distance?

The time it takes to sail a certain distance depends on various factors, such as wind conditions and the sailing speed of the boat. By calculating the sailing speed and dividing the desired distance by it, you can estimate the sailing time required.

Can I sail for 8 hours in a day?

Yes, of course you can! With an average speed of 6.5 knots, you can travel 52 nautical miles in 8 hours.

Average Speed of a Sailboat

What are the average cruising speeds for a 30-40' displacement and semi displacement hull sailboat?  

6-9 knots depending on conditions and the boat.  

If you are talking about averages over the course of a long sail, I think that is a bit high.  

As was said, this is a tricky question. But, for consideration, a well-sailed cruising boat on passage will make about 75-80% of her hull-speed potential over a 24-hour period. Example: Waterline length: 34' Hull speed: 5.8*1.4 = 8.2 knots 80% of hull speed: 6.56 knots 24-hour run: 157.4 nm Mine does a bit better, averaging 6.7 knots or 160 nm per day on offshore passages on a 34.2' waterline (27K lbs displacement, 42' LOA). Obviously, there are many variables. But, the "80% rule" often comes close, I've found. Bill  

I'd agree with what our esteemed moderator has said. Low, about 4 knots. High, about 6 knots. Subject of course to weather being higher or lower than usual. With GPS, you'll know your speed over the bottom. With a wood or stryofoam chip, timed from bow to stern, you'll know what your speed through the water is. They you'll know if you're sailing in current. But our estimates on the web don't mean much to you on the water, you'll have to take both an over-ground and a through-water speed, then compare to see if you are in a current and if so what its direction is.  

All these guestimates also need to take into account the point of sail and the wind speeds vs the different designs. I suspect there's little difference between "displacement" and "semi-displacement" designs. However a boat that can outright plane in certain conditions will have a much higher potential threshold with the right wind speed, course and sea state. JRP's estimates for overall average speed look good.  

To figure out how long it will take to get somewhere, figure 5kts as a average. When bragging at the local sailing bar, figure the hull speed plus 10%. Unless you are in the trade winds, then figure on 75% of hull speed depending on the skipper, condition of sails, the load of the boat multiple times a random number derived from adding up the letters of the words "silly question". Sorry, had to do it.

What are the average cruising speeds for a 30-40' displacement and semi displacement hull sailboat? Click to expand...

Thanks for all the feedback. Everyone's answers was exactly what I was looking for.  

One variable no one mentioned is where you are cruising. When we crossed Lake Michigan years ago, we used to figure 5 knots as minimum speed, because the run was about 60 NM where we usually crossed, and we always liked to do it in the 7 AM to 7 PM time frame. If the wind fell off and our speed dropped below 5 knots, we would start the engine. However, when crossing an ocean, you really don't want to start the engine because you don't carry enough fuel to run the engine for a couple weeks!  

Gunny!! Yer back!! Where ya been??  

Hey CamJ Just living life. Merger-ed myself out of a job, took up selling health and life insurance. That took sometime to get the license and learn selling skills. I still get out in the bay. Have more time to go thru the board since I work from a "home" office, (read bunny slippers, coffee, computer, and telephone.) (Ok I really don't wear bunny slippers).  

I'll chime in on the 5 kts average. That's what I use when cruising under conditions that don't allow for long term use of engine when the wind dies. The times you are bombing along at 8 kts are offset by the times when you are drifting in circles. And of course all bets are off it you are going to windward in light stuff.  

I use a 6 knot average when I am planing a cruise. I find it easier to do the time, distance and speed calculations in my head when I use 6 knots. I aways late though.!!!  

Of course you all realize that the amount of marine growth on the bottom makes a difference also. Ultra clean bottom 6+ kts Average clean bottom 5+ kts grassy bottom 4+ kts botanical gardens on the bottom 2+ kts Now how close am I??
