One of the most popular cruising vessels is cruising catamarans. Cruising catamarans are popular thanks to their stability and space, but some sailors have concerns about cruising catamarans’ speed. So, how fast are cruising catamarans?

Sailing cruising catamarans can travel at an average of 9-15 knots and max out around 35 kts. Power Cruising catamarans have a maximum speed of 70 knots but averages around 20-25 kts. How fast a catamaran can go also depends on the load it is carrying, its structural design, and its engine power.

This article explores details of what affects a cruising catamaran’s speed. It also considers how fast sailing and power cruising catamarans can go, along with some of the most rapid cruising catamaran models available today.

How Is a Cruising Catamaran’s Speed Measured?

To better understand a cruising catamaran’s speed, it is essential to consider how a boat’s speed is measured. Boat speed is measured in knots , which is one nautical mile per hour, (or 1.15 mph). One nautical mile is approximately 1.15 land miles.

The speed of a catamaran is calculated by a GPS tracker that records the distance sailed every hour.

How Fast Are Sailing Cruising Catamarans?

The wind powers sailing cruising catamarans – their speed depends on the speed of the wind. If there is a lot of wind, more wind equals higher a faster boat. However, if there is little to no wind, the catamaran won’t move very fast or very far.

At about 14-16 knots of wind speed, sailing catamarans can average 9-12 knots . Some high-end sailing catamarans can be even faster. For instance, the Gunboat 62 Tribe can sail up to 36.6 knots when the wind is between 35-45 knots.

How Fast Are Power Cruising Catamarans?

Unlike sailing catamarans, power catamarans do not rely on the wind to move. Instead, they are powered by fuel (usually diesel). This means that they can travel faster than sailing catamarans and that their speed is more reliable.

Under light loads the Power catamarans can travel at between 20-25 knots. When the load is higher, power catamarans speed drops to 15-20 knots.

Some high-end catamarans, such as the Freeman 47, can reach up to 70 knots .

What Affects the Speed of a Cruising Catamaran?

There are several features of a cruising catamaran that impact its speed. These include:

The type of hull. The less the hull is submerged into the water, the faster the catamaran will go. When they are submerged, hulls create drag which slows the velocity of the boat.
The beam/length ratio. When a catamaran has a higher surface area (stable base), it can better withstand stronger winds, therefore allowing it utilize more of the wind before needing to reduce sail area.
The material used to construct and reinforce the vessel. When areas of the catamaran are filled with foam, it decreases the catamaran’s weight while ensuring that stability is maintained. As a result, the catamaran has a lighter weight, making it faster.
The type of propellers. Propellers are an essential part of a vessel as they act as brakes, which are necessary to slow down and stop a boat. However, many modern cruising catamarans have folding propellers that reduce the boat’s water resistance when the engine is turned off. As a result, the catamaran can travel faster under sail.
The engines. The higher the horsepower of the catamaran’s engine, the faster it can go. Most newer catamarans have two engines which makes them faster than the older, one-engined counterparts.
The load of the catamaran. Each catamaran has a load-carrying capacity. If the amount of weight the catamaran has onboard exceeds this capacity, it will “sit” lower in the water and significantly slow down the catamaran’s speed.
The sail trim and reef. When sail area is reduced (called reefing), the catamaran slows down (in most situations). Properly trimming the sails will also enhance performance.

In addition, catamarans will be faster downwind . Going downwind removes the headwind and will many times allow you to surf with the waves.

Why Should You Look for a Faster Cruising Catamaran?

The old adage is that “slow and steady” wins the race. However, when it comes to cruising catamarans, many sailors believe the faster, the better. Faster catamarans are preferred because they:

Allow the crew to quickly move the catamaran out of bad weather conditions, protect the vessel and passengers on board.
Allow the captain to more predictably calculate Estimated Time of Arrival (ETA).
A shorter time spent in bad patches of sea making big ocean crossings safer and more enjoyable.

What Are the Fastest Cruising Catamaran Models?

Some catamarans have been recognized and won awards for their speed. Some of these models are explored below.

Freeman 47 (Power)

Freeman catamarans are symmetrical catamarans that have especially been designed to carry a heavy load without sacrificing speed. Released in 2020, the Freeman 47 has quad 450R Mercury outboards that allow it to travel at 70 knots.

In addition to the outboards, many features of the Freeman 47 allow it to move faster. It has a fuel capacity of 1000 gallons (3785 liters) and a maximum power of 1800 HP.

Conclusion

A catamaran’s speed depends on its design, its load, its type, and on a variety of other factors. However, on average, most sailing catamarans can achieve between 9-15 knots, while power catamarans can, on average, achieve between 20-25 knots. If you are looking to splurge for the best on the market, some power catamarans can reach 50-70 knots.

If you’re looking to buy a cruising catamaran, make sure you use the information you have gained to assess the speed of the catamaran you are considering. A faster catamaran can make for safer and more exciting sailing. Ultimately, it will make your cruising experience more enjoyable and satisfying.

How Fast Do Catamarans Sail? Average Sailing Speed of a Catamaran

In most aspects, sailing a catamaran is very similar to sailing a monohull. If you learn to sail on a monohull then most of the skills are transferable. But, there are a couple of subtle differences that we will analyze further in this article. A catamaran is generally more balanced on the water and can be faster than a multi-hull vessel. And, cruising on a sailboat with a cat hull will be much faster than cruising on a sailboat with a monohull. Therefore, a catamaran hull is able to achieve the speeds of a racing monohull and is also more comfortable to sail on.

A tri-hull is even much better as they’re designed towards the performance end of the spectrum. And that is why they double the speed of a racing monohull. So, let’s analyze this subject further in this article and see what’s the average sailing speed of a cat. Follow me!

Catamaran Vs Monohull Speed: Are Cats Faster than Monohulls?

Not all cruising cats are always faster than an equivalent length monohull. But, many well-designed and balanced multihulls can easily surpass the speed of their monohull cousins. And, it’s not fair to mass all cats into one example, but performance cruising catamarans like the Nautitech or Neel trimarans distinguish from others. Their narrow waterline beams, hull chines, deep and fine keels, and rudders as well as efficient sail plans will typically be faster than the average cruising monohull.

“The fun of sailing is proportional to the speed of sailing”, as an American designer, L. Francis Herreshoff, said. And, it’s basically true because when we sail and see another boat heeling in the breeze, we also feel we want to do the same. This is because for many sailors speed means much more than just fun. You should, however, consider keeping your cat as light as possible if you want to maximize speed. I know that keeping your sailboat light is difficult but it’s of importance if speed is your main goal.

Keep in mind that a boat’s speed has won wars and has also been a contributor to safety. In the past, a fast warship was able to outmaneuver its adversary or escape from a boat with more firepower. And just as proven in history, the speed of a sailboat is important and provides a faster boat with more options.

Monohull VS Catamarans Differences

When tacking, you must work hard to keep your speed consistent in the tack and always ease the mainsheet to avoid “windvaning.” When the larger mainsail on a catamaran attempts to turn the boat back towards the wind, this is known as windvaning.
On a monohull, you must be extremely cautious about an unintended gybe. Meaning that you must gybe much more slowly. On a catamaran, you can take advantage of the increased speed and sustain it while gybing to help depower the main.
On a monohull, and when winds increase, the boat starts heeling. This automatically informs you that you have too much sail up and it’s time to reef. And, as catamarans don’t heel, you have to be very careful when to reef the massive main. Most of the time, you will throw in the first reef at 18-20 knots of wind speed. The second reef will be put as the wind gets closer to 23-25 knots. The above-mentioned always depend on the size and type of your vessel.

Wind as a Main Factor for Speed

Thanks to tech evolutions in radar, satellite, and computer technology, a five-day forecast is as accurate as a two-day forecast was back in 1980. A multihull’s higher speed also contributes to easier and safer planning of ocean passages around weather windows since exposure time will be less. Moreover, meteorological prediction for shorter periods is far more accurate. Keep in mind that when sailing faster you also introduce the concept of apparent wind to the strategy of efficient sailing.

Multihull speed upwind? Sailing upwind, the catamaran usually experiences more apparent wind across the deck since it’s sailing faster. Therefore, the sails will feel more pressure, which will make the boat perform even better. And, of course, the concept of apparent wind contributes to the joy of sailing, as it adds another dimension to it. When sailing towards a downwind destination, fast multihulls are able to sail at smaller wind angles. Subsequently, this brings the apparent wind forward of the beam, hence optimizing the angle of attack on the sails.

While cats will fly gennakers, code-zeros, or asymmetric spinnakers, monohulls mostly set symmetric spinnakers to the poles. And most importantly, their boat speed will often cancel out the true wind and will reduce the apparent wind and performance. The faster the multihull is the more it is able to take advantage of the apparent wind and tack downwind towards its destination. Although it might be sailing twice the distance, it will arrive at the downwind mark quicker because its Velocity Made Good (VMG) will be faster.

Performance Characteristics

Bear in mind that cats require four times the power to double their speed. But, a mono-hull vessel requires eight times the power to double the speed. This is due to the fact that a cat has less resistance in the water. However, this is great in terms of conserving and using less energy. Catamarans are also more stable in the water. This stability is effective at resisting heeling or capsizing. In other words, a multi-hull vessel requires four times the force to capsize as a similar-sized mono-hull vessel.

Most of the time, sailing in a catamaran is smoother and facilitates activities that are not always possible on a mono-hull sailboat. In addition, as catamarans have less water resistance, they are generally faster than mono-hull vessels. As their hulls are smaller, this means that they have a smaller bow wave to fight. The bow wave is a wave created by the displacement of water by the bow of a ship. After a certain speed, the boat has to start hauling itself over its own bow wave. Meaning that the larger hull a boat has, the larger its bow wave will be and the more power will be required in order to fight it.

Since catamarans have two small and narrow hulls, they don’t have much of a bow wave. This is one of the reasons they are normally quicker than a monohull vessel of comparable size. Catamarans can travel at speeds of up to 30% faster than monohull boats. Catamarans have the disadvantage of taking longer to transform than monohulls.

Lastly, the thing that makes monohulls harder to sail is heeling and smaller spaces. In stronger winds, monohulls tend to heel. This results in making most tasks a bit more difficult to perform. Whether you’re heading forward to reef, trying to winch in a sail, or move about the boat, sailing on a heeling boat is always more difficult. However, cats have extra stability and room, and this allows for much easier movement around the boat as they do not heel. And, for this reason, catamarans are often considered easier to sail.

How Fast Are Catamarans Compared To Other Boat Types?

There are two main factors that determine the speed of ships. The first one is the hull type. There are hulls that stay beneath the water more or less than others. But, keep in mind that the less the hull is underwater, the faster it can go. This is due to the fact that the less of the hull underwater, the less the drag created when sailing. The other factor is the length of the boat. And, reasonably, the longer the boat, the faster it can go. Every boat has a maximum hull speed that can’t be exceeded. This can only happen in case the boat can plane on the water’s surface or be lifted on hydrofoils. For most boats, the longer the boat, the higher the maximum hull speed is.

Sailing catamarans typically average about 10 knots while pontoon boats average about 16 knots. As for powerboats, they can average anywhere between 30 and 50 mph. Most average sailboats are designed with monohulls and they average from 6 to 9 knots depending on wind conditions. Generally, sailboats average between 8 and 12 mph, again depending on weather conditions. This includes mono-hull between 6 to 8 mph and cats or trimarans between 9 and 10mph.

Speed and Comfort Considerations For Cats

You have a lot of choices if you choose to buy a catamaran. You have the option of prioritizing speed or comfort. After you’ve decided to buy a catamaran, the type of catamaran you can consider is determined by where you’ll be using it and what you’ll be doing with it. In addition, make sure that you look at what type of water you will be traveling in, your crew members, and what type of speed you want to achieve.

Storage is an important consideration to make before purchasing a catamaran. Due to the beam, or width, of a catamaran versus a regular mono-hull vessel, you are often charged for two slips if you wish to store your boat in a marina. Moreover, catamarans are a great option for those who get seasick because they have a more stable ride and more open air space. You have more windows and visibility since the living quarters are not within the hull and below the water’s surface.

Sailing and power catamarans are both great choices. In addition, for low winds or conditions such as docking in a marina, sailing catamarans may be equipped with backup power engines. Twin-engine catamarans can have more power and precision than mono-hull vessels.

Main Advantages of Catamarans

Space! If you want to opt for more interior and exterior space then the two separate hulls of a catamaran can often double the amount of social space than a monohull of the same length.
Catamarans are far more stable than monohulls. For this reason, they don’t heel when sailing, and are less prone to rocking when at anchor. This factor also contributes to comfortable sailing.
Catamarans have a shallow draft which allows them to enter shallower areas. Keep in mind that in the South Pacific, most lagoons are 6 to 8 ft in depth. This depth doesn’t allow for monohulls to enter, but a catamaran can easily enter these areas.
Stability is another big plus of cats. A cat isn’t that susceptible to the effects of wave action and it also doesn’t heal the way a monohull does. Therefore, it’s much easier to walk around on deck and within the interior of the cat while underway.
In terms of speed, and mostly for downwind sailing , cats are faster than monohulls. This particularly applies to downwind runs, reaches, and broad reaches.
More light, customizable, and airy living area. On a catamaran, the living space is usually situated in the middle of the boat and built on the bridge deck. But, in a monohull you go down into the hull where it is darker and less airy.
More storage space and room for extra systems, provisions, and general sailing equipment. These may include air conditioning, heaters, oven, watermakers, generators, larger fridges, and freezers, etc. And, if you’re a liveaboard, then living on a cat is far more comfortable than living in a sailboat. You have more interior, exterior, and storage space as well as stability and speed in terms of sailing performance.
Many modern cats have flybridge helms. And of course, no monohull achieves this visibility from the helm provided on most modern catamarans.
The galley, main salon, and cockpit are all located on one level , above the waterline.
Because the majority of living space is above the waterline , there’s a better flow of ventilation on a cat making the need for air conditioning somewhat less important during the daylight hours.
When you plan to set sail, you almost never have to rush around stowing stuff or using bungee cords to hold things in place. Except in relatively rough waters, most things stay put.
Since catamarans lack a large, heavy keel filled with lead, they can float even if they’re holed. Production cats are constructed with so much buoyancy that sinking them is nearly impossible.
Catamarans are usually easy to dock because you have two motors and two rudders. Additionally, there’s also no need for a bow thruster.
Most catamarans are able to turn 360 degrees within their own length.

Average Sailing Speed of Catamarans


Sport Catamarans	30 knots
Cruising Catamarans	15 knots
Racing Catamarans	45 knots
Power Cruising Catamarans	70 knots
Swath Catamarans	30 knots

How Fast Do Catamarans Sail? – The Bottom Line

Bear in mind that not all catamarans are created equal. In other words, catamaran speed is relative. The most important benefit of the speed of a multihull is the ability to outrun bad weather. Meaning that you’re able to average 9-10 knots on a catamaran rather than 6-7 knots on a monohull. Subsequently, this will give you more options in your strategy to avoid bad weather. In general, sailing catamarans typically average about 10 knots. Higher maximum and average speeds are what makes cats distinguish as well as their stability. These are the most important characteristics which makes many sailors prefer cats rather than monohull boats.

How Fast Do Catamarans Go? 5 Examples (With Pictures)

A catamaran is generally more balanced on the water and can be faster than a multi-hull vessel.

Unless you compare them to foiling monohulls like the new America’s Cup boats that sail at over 50 knots, they are not recreational vessels.

In this article, we will look at how fast each type of catamaran will go.

Table of Contents

Here are the numbers before we dive into the details:


Sport Catamarans	30 knots
Cruising Catamarans	15 knots
Racing Catamarans	45 knots
Power Cruising Catamarans	70 knots
Swath Catamarans	30 knots

Average Speed For Sailing Catamarans

Catamarans can vary in size from 14 ft to over 100 ft. Catamarans can come in a wide variety of design types.

Sailing Catamarans have been attempting to make advancements over their mono-hulled counterparts.

These advancements include:

Foils that assist with lifting the vessel out of the water.
Stability advancements.
Racers that can maintain their speed while out in the ocean.

3 Different Types of Sailing Catamarans:

1) sport catamarans.

One type of sailing catamaran is a sport catamaran, which is otherwise known as recreational. These are typically supposed to have a small crew and launch and land on beaches.

Sport catamarans do not normally have living quarters and are ideal for day trips. Resorts or other rental services often use these.

These can also be used for racing.

Sport vessels have been known to travel over 30 knots but can speed over 40 knots in the proper conditions.

2) Cruising Catamarans

Another type of sailing catamaran is a cruising catamaran. These often come with complete living accommodations, so they sacrifice speed over their sportier counterparts.

They can average between 9 and 10 knots, depending on the conditions. The top speed is typically around 15 knots.

It would be best if you were careful with catamarans that have living quarters. The more you weigh it down, the less speed you will have.

3) Racing Catamarans

The final type of sailing catamaran is an ocean racing catamaran.

These boats are large and can reach over 100 feet in length.

The top speed of this type of catamaran is around 45 knots.

Because of the prize money for entering these in races, much research goes into their advancement.

Average Speed Of Power Catamarans

Catamarans with power motors fill a different type of boating category.

These are commonly used when speed and smoothness are favored over space or capacity.

Because of their stability, catamarans are good vessels for combating seasickness as well as transportation. We have a separate article here with all you should know about catamarans and (how to overcome) seasickness .

On a commercial level, these can be used for ferries for both people and vehicles. They are used for short term travel, often to or from islands.

Like sailing catamarans, there are a few types of power catamarans.

1) Power Cruising Catamarans

Similar to sailing cruising catamarans, they also have power cruising catamarans. These also have living quarters and are stable while out on the water. The speed of these vessels highly depends on the motors equipped and the size of the boat itself.

Like passenger transport or ferries, catamarans have a high speed of about 40 to 70 miles per hour.

These are made to travel at great speeds to allow their commuters the shortest possible ride to their destination.

The military also utilizes power catamarans. They use power catamarans to transport military cargo. These ships are ideal because of their speed, holding capacity, and ability to venture into shallow ports.

2) Swath Catamarans

They also have small-waterplane-area twin-hull vessels. These are called SWATHs.

These differ from the average catamaran because they also have submarine-like hulls that stay completely under the water.

Due to the hulls being submerged, they are not normally affected by waves. These are used most often in the ocean as research vessels. They can also be used for certain types of yachts. Because of their stability, they are good vessels for furniture that will not require as much securing.

These often travel between 20 and 30 knots.

Some catamarans are designed for wave piercing. These are made to pierce through waves rather than sail over them, causing them to be faster. These can be used as passenger ferries, yachts, and military vessels as well.

3) Whitewater Catamarans

There are also recreational catamarans made for whitewater travel. These are sometimes called “cata-rafts.”

They are made using two inflatable hulls connected with a scaffold. These are lightweight and perfect for whitewater sports.

They are even able to be packed away in a backpack. They can take up to 20 minutes to assemble, including inflation.

They have high speeds on white water rivers and can be most compared to a canoe, kayak, whitewater raft, or other white water vessels.

Performance Characteristics Of Catamarans

Catamarans require four times the power to double their speed. A mono-hull vessel, however, would require eight times the power to double their speed.

This is because a Catamaran has less resistance in the water.

This is also good for conserving and using less energy.

Catamarans are also more stable in the water. This stability is effective at resisting heeling or capsizing. A multi-hull vessel would require four times the force to capsize as a similar-sized mono-hull vessel.

The general sailing in a catamaran is smoother and allows for activities that are not always possible on a mono-hull sailboat.

Are Catamarans Faster than Mono-Hull Vessels?

Because catamarans have less water resistance, they are generally faster than mono-hull vessels.

This is because their hulls are smaller, which means they have a smaller bow wave to fight.

A bow wave is a wave created by the displacement of water by the bow of a ship. After a certain speed, a boat has to start hauling itself over its own bow wave.

The larger hull a ship has, the larger its bow wave will be and the more power required to fight it.

Catamarans have two small and narrow hulls, so they do not have much of an issue with their bow wave. This is one reason they are usually faster than a similar-sized mono-hull vessel.

Catamarans can be between 20-30 percent faster than their monohull counterparts.

Issues with catamarans over mono-hulls are that they can take more time to turn.

How Is The Speed Measured?

Boats commonly measure speed using GPS tracking devices to measure distance traveled. Speed while sailing is measured in knots. A knot is one nautical mile per hour, which equals about 1.15 miles per hour.

How Fast Are Catamarans Compared To Other Boat Types?

Sailing catamarans typically average about 10 knots.
Pontoon boats average about 20 mph.
A powerboat cruiser can average anywhere between 30 and 50 mph.
Cigarette boats can even reach close to 90 mph in the proper conditions.
Sailboats average between 6 and 12 mph depending on wind conditions. This includes mono-hull between 6 to 8 mph and catamarans and trimarans between 9 and 10mph

Two different factors can determine the speed of sailing ships:

1) The hull type as listed above.

Different hulls rest in the water more or less than other types. The less of the hull that is underwater, the faster it can go.

This is because the less of the hull in the water, the less drag created while sailing.

2) The length of the boat

The longer the boat, the faster it can go. Every boat has a maximum hull speed that cannot be exceeded unless the boat can plane on the water’s surface or be lifted on hydrofoils. For most boats, the longer the boat, the higher the maximum hull speed is.

Speed Vs. Comfort Considerations For Catamarans

If you are looking for a catamaran, you have a lot of options.

You can choose to prioritize speed or comfort.

After deciding to purchase a catamaran, the type of catamaran you should look at depends on where and what you are using it for.

You will want to make sure that you look at what type of water you will be traveling in, how many people you are traveling with on average, and what type of speed you hope to achieve.

One thing you will want to keep in mind before the purchase of a catamaran is storage. If you intend to store your boat in a marina, you are often charged for two slips due to the beam, or width, of a catamaran versus the standard mono-hull vessel.

Catamarans can be beneficial for those who get seasick because they offer a steadier ride and the ability to have more open air space. Because the living quarters are not inside the hull and under the water’s surface, you have more windows and visibility.

Both sailing and power catamarans are viable options. Also, sailing catamarans can come with back-up power engines for low winds or situations such as docking in a marina.

Catamarans that have twin engines can offer more control and precision than those on a mono-hull vessel. This is good for tight and busy areas or navigating marinas.

Overall, there are plenty of options for you, and they offer many benefits over their mono-hull counterparts.

Average Speed of a Sailboat (Plus Top Speed)

What Is The Average Speed Of A Sailboat? | Life of Sailing

Last Updated by

Daniel Wade

June 15, 2022

Going fast in a sailboat can be lots of fun. But what is the average of a sailboat? Well, let's find out.

The delight and gratification that comes from speed can be a big plus for adrenaline-seeking sailors. Well, nothing can fire up the adrenaline more than having a speedy boat ride out on the water. This is essentially why having an idea of how fast a sailboat can go is of great importance. When it comes to looking at the speed of a sailboat, it can be crucial to consider the types of activities that you'll be using your sailboat for. In fact, your sailboat should only be considered ideal if it meets the level of expectations required of it in terms of speed and activities on the water. Even with this, the speeds of sailboats can vary based on several factors. But what is the average speed of a sailboat?

The top speed of a sailboat will vary based on its size and purpose. For example, high-end racing sailboats are purposely designed to reach maximum speeds while larger and bulkier sailboats may be slower due to drag and friction. That being said, the average speed of racing sailboats is 15 knots (17 mph). On the other hand, the average speed of cruising sailboats is 4-6 knots (4.5-7 mph) and can attain a top speed of 7 knots (8 mph). In essence, cruise speeds of over 8 knots are quite normal.

Let's get into the details.

Table of contents

Measuring Sailboat Speed

The nautical measurement of speed is the knot. According to the World Sailing Speed Council, one knot is equal to about 1.15 mph. The knot measurement is dependent on the circumference of the Earth. So if your sailboat is cruising at an average speed of 1 nautical mile per hour, it means that it's cruising at a speed of 1 knot.

Modern sailboats have GPS tracking devices that can be used to measure the distance covered, as well as the speed at which the sailboat is sailing.

Factors that Determine the Speed of a Sailboat

Different types of sailboats can attain different speeds. There are several factors that can determine the speed of a sailboat. Let's take a look.

The Length and Size of a Sailboat

While the speed of a sailboat will depend on several factors such as currents, wind conditions, and many other factors as we'll discuss later, the most important thing that can influence the speed of a sailboat is its size and length. You may be asking yourself; what's the connection between the length of a boat and its speed?

Well, the ability of a sailboat to go fast depends on the harmonizing act between its length and the power that drives it. When a sailboat moves through the water, it creates a pattern of waves. These waves include one along the side of the sailboat, which produces a ridge of water at the bow and a trough at the stern.

If the length of the wave is almost equal to the length of the boat, it creates a huge ridge that shoves the sailboat back into its trough, thereby slamming it up against an almost dense wall of water resistance. This then gives the sailboat sufficient speed to lift its bow out of the water and the ability to skim above the bow waves while allowing it to overcome the resistance that the water or the waves create.

A sailboat, of course, needs a lot of power to get over the hump in the resistance curve. So a longer boat will have a higher speed than a shorter boat. This is because a longer sailboat will create longer waves across its hull and move faster. On the other hand, short sailboats tend to generate shorter waves, thereby will have reduced speeds. In essence, it's almost impossible for a sailboat to travel faster than the speed of a wave if the wave is longer than the boat.

In most cases, boat designers create extreme lengths to get boats over the mound of the wave resistance. While a lightweight boat can easily achieve this, it can leave you shorthanded in heavy winds as it can be easily pushed by the winds. Again, it may not have the stability needed to carry enough sails to get the appropriate power to sail on the water. So if the boat is light, it should at least have a double hull to at least compensate for its instability.

The Shape of the Hull

This may be hard to believe but some hulls are more efficient than others when it comes to creating the wave resistance that is needed to move the boat. Generally, hulls should be very slim and carefully shaped. Keep in mind that a sailboat that has a hull that's shaped like a fat tub will not be as fast as a sailboat with a very slim hull even if they're of the same length.

A proper indication that the hull has the ability to be faster depends on its aft or buttock lines. If a hull has a straight line from the lowest point of the hull to the transom and the transom is a little bit wide, the boat will not only be stable but will be much faster. On the contrary, a hull that curves a lot but has a narrow stern may not be that fast. In essence, hulls play an integral role in slicing through the water and do not push water aside and down.

Comparing the Speeds of Catamarans and Monohulls

Are catamaran or trimaran hulls more superior to Monohulls in terms of speed? Well, cruising on a sailboat with a cat hull will be much faster than cruising on a sailboat with a monohull by 25%-30% if the two sailboats are of the same length. A catamaran hull will not only achieve speeds of a racing monohull but will be more comfortable to sail on.

A tri-hull is even much better in the sense that they're generally designed towards the performance end of the spectrum. They will, therefore, double the speed of a racing monohull.

The only downside of a cat and trimaran hull is that they're more sensitive to loading and their performances will significantly suffer if they're loaded. On the other hand, a monohull can perfectly handle loading and this is a huge advantage is you're planning to sail with a crew. To this end, you should consider keeping your cat or tri boat as light as possible if you want to maximize speed. We all know that keeping your sailboat light is as difficult as they come but it's of importance if speed is your main goal.

Monohull (6-8 knots)

Most average sailboats are designed with monohulls. They're generally displacement hulls designed to split through the underwater. This not only stabilizes the boat but slices through the water smoothly. If you want to make a monohull sailboat much faster, you can consider raising the entire hull above the water.

Catamarans and Trimarans (9-10 knots)

Unlike monohulls, cats and trimarans are located on top of the water. This means that they'll be displacing less water, thereby making them a lot faster. The only downside is that this design will make the boat less stable, which can be a cause for concern given that safety should always come first while on the water. This is essentially why catamarans and trimarans have two and three hulls respectively. This will, however, make the boat extremely buoyant.

Waves play a critical role not just in the speed of your boat but also in the safety of your boat. We all know that waves are very unpredictable. They can be calm and gentle but can suddenly become wild, confusing, irregular, and angry.

Generally described as freaks or rogues, waves can be very dangerous. They can bully your boat and attempt to roll it over. Waves can also make your boat faster or slower. As such, waves can either positively or negatively affect the speed of your sailboat. Given that calm waves cannot be appropriate in achieving the maximum speed of your boat, the right wave condition that should enable your sailboat to move faster should overlap and interfere in the right way.

The wind is the only thing that propels sailboats. The wind will fill up the sails, which is then used to move the boat. Both true winds and apparent winds can be integral in moving the boat forward. True wind is essentially the type of wind you feel when you stand still and it's what pushes a boat. Needless to say, strong winds may move a sailboat faster than calm winds but this may depend on the wind direction.

How to Improve the Speed of Your Sailboat

Having looked at the average speed of a sailboat, as well as factors that may affect its speed, it's important to highlight how to improve the speed of your sailboat.

It's important to make sure that your sailboat is properly designed to attain maximum speed. The sailboat should also be properly maintained and serviced to work at maximum speed. Make sure that the hull and foils are clean and in perfect shapes. Here's what to do.

‍ Make sure that the foils do not have seaweeds or plastic bags
Ensure that the hull is in tip-top shape and can hold tension
Make sure that the sails are in the right conditions
Make sure that the masts have the right stiffness

You may have a lot of difficulties reaching your targeted speed if the weight of the crew exceeds the appropriate capacity of your sailboat. This is because there will be some sort of drag and tension and this may significantly hinder the speed at which the boat travels. In essence, a lighter boat may be a lot faster than a heavier boat. This is what you should do.

‍ Make sure that the weight is appropriate
Ensure that the boats overall weight is moving aft and out appropriately
Make sure that the maximum weight is not exceeded

The settings of your sailboat can either negatively or positively affect its speed. For instance, you should make sure that the mast rakes, mast step position, shroud tensions. Jib car position, vang tension, and keel position, as well as any other part of the sailboat, are perfectly set to make the boat faster.

You should compare various settings and figure out which type of settings gives you maximum speed. Here are some of the things to do.

‍ Ensure that jib cars are in the right position
Make sure that your mainsails are in the right position
The vang tension should be efficient

The technique you use on your sailboat can make a difference when it comes to your speed. Techniques such as steering and trimming can be a huge speed factor, particularly when the conditions at sea are difficult. You should also have varying trimming techniques. Here are some important skills.

‍ Know how to steer perfectly
Know how to control primary upwind
Know the right amount of curl to have in your kite
Make sure that you're pumping efficiently
Know how to play the jibs and genoas

These factors can be of great importance in increasing the speed of your sailboat. You can use them efficiently next time you want to be up to speed.

Bottom Line

Sailing speed is, without a doubt, one of the most favorite discussions among sailors. Most sailors often try to figure out how to make their sailboats faster or why a given sailboat is faster than another one. In essence, the average speed of a sailboat ranges between 4 knots to 15 knots but this may depend on the size and type of the sailboat, as well as other factors. This means that the average speed of sailboats is 8 knots but there several factors such as the type of the hull, waves, and wind conditions can affect the speed of your sailboat.

It's, therefore, important to know how these factors may affect your speed and what you need to do about them. For example, your sailboat may not be as fast as you may want if it's not properly prepared or maintained.

I've personally had thousands of questions about sailing and sailboats over the years. As I learn and experience sailing, and the community, I share the answers that work and make sense to me, here on Life of Sailing.

Sailing Catamaran Speed

You’ve probably heard that one of the best reasons to get a catamaran is because they’re fast. After all, there’s a race any time there are two sailboats on the same waterway.

But like all things in boating, speed is a relative term. Catamarans seem fast to those coming from slow and heavy monohull sailboats, but cruising catamarans are still pretty slow vessels. There are indeed high-tech racing catamarans breaking speed records all the time. Still, the vessels that most liveaboard cruisers venture out on are only slightly faster than their monohull counterparts.

For this article, we will look at the types of catamarans people live on and cruise on. Forget about those fantastic America’s Cup yachts or those multihull go-fast fishing boats for a few minutes.

I have had experience cruising and living aboard both catamarans and monohulls. For five years, my wife and I enjoyed catamaran sailing on a Lagoon 380. We then switched—for many reasons—to a Cabo Rico 38. The Cabo Rico is a traditionally-designed monohull with a full keel and a heavy displacement. In other words, it’s about as far away from a “speedy” catamaran as one can get.

How fast can a catamaran go, measuring catamaran speed, catamaran speeds vs monohull speeds, sailing cruising catamarans, performance cruising catamarans, racing catamarans, power cruising catamarans, catamaran top speed, faqs – how fast are catamarans.

There’s no doubt that catamarans are some of the fastest sailboats around—but there’s also a lot of misinformation and misunderstanding online about how fast they really are.

Realize that not all catamarans are created equally. There are cruising catamarans built to carry their passengers in comfort. And then there are racing catamarans built for nothing but speed. Somewhere in between, there is a poorly-defined category of “performance cruising” catamarans that stir passions.

So, are catamarans fast? Well, it’s all relative. But, if you compare them to monohull sailboats of similar sizes and capabilities, the catamarans are usually faster for several reasons.

The speed difference is even harder to measure in the cruising catamaran category. One of the reasons catamarans beat monohulls during races is because they are built light with no ballast. But a heavily-laden cruising cat ready for an ocean crossing is hardly “lightly loaded.” Will it still beat a similarly heavily-laden monohull? Sure! But probably not by as much as you might think.

Boats measure their speed in knots. Traditionally, this was measured by a tool known as a knot log. The modern equivalent is an underwater instrument with a spinning wheel that effectively measures the speed of the water passing over the hull. So long as no currents are present, that speed will equal the boat’s speed over the ground (SOG).

Satellite navigation allows us to measure our SOG more accurately, but this isn’t a great indication of boat performance since it will be affected by tides and ocean currents.

For landlubbers, one knot is equal to about 1.15 statute miles. So, in other words, when we say that a sailboat cruises at 6 knots, it means it’s going about 7 mph.

But before going any further, consider this—the maximum speed that a sailboat makes is generally a pretty meaningless number. Maybe the knot log pegs to 13 knots for a few seconds, thanks to a strong gust of wind while you’re headed down a large swell. Does this mean you’re driving a 13-knot boat?

A voyaging sailor who has made a long passage will have little interest in this sort of number. When you’re crossing oceans, what really matters is how many miles pass under the keel each day. The more miles you tick off, the shorter the passage. So most sailors learn quickly to look past the “fastest speed in knots” number and find real-world stats on passage miles.

Comparing speeds between radically different sailing vessel hulls is like comparing apples to oranges. Even seemingly similar boats, like “cruising sailboats,” the differences between one and the other are endless.

For example, let’s say you wanted to compare 38-foot monohulls to 38-foot catamarans. The speed of a monohull is limited by waterline length, which means you’d have to look at a hull that is significantly more than 38 feet in most cases. On the other hand, the catamaran is known for long swim platforms on inverse transoms and plumb bows—meaning most 38 foot cats have nearly 38 feet of waterline.

Then, what sort of hull design makes a fair comparison to a catamaran? Would it make sense to compare a transitional, salty 38-footer with a full keel? Probably not. Most sailors interested in the cruising catamaran lifestyle would more than likely be comparing it to a modern monohull with a flatter bottom, fin keel, and spade rudder.

What about the catamaran? There’s a lot of variation in the catamaran field regarding performance. If speed is your goal, you likely want to compare the high-end performance brands—Outremer, Gunboat, HH, and the like. These boats are becoming more popular, but most cruising cats you see on the water are not performance models. Instead, they are the big and comfortable cruisers made by Lagoon, Leopard, or Fountaine Pajot.

Finally, how can you fairly compare the stats? Boats sail differently in different wind speeds and at different points of sail. In other words—there are a lot of variables that make it hard to answer the question, “How fast can a catamaran go?”

Polar charts for each vessel can provide some clues to make a somewhat fair comparison. Polar charts are graphical plots of a sailboat’s performance in different wind conditions and at different points of sail. Manufacturers seldom publish since no two are ever perfectly alike. They are less of a boat specification and more of one sailor’s results for a particular boat. Most owners make their own polar diagrams, but they’re still a tool for those looking to get an idea of a model’s performance in the real world.

Speeds of Various Types of Sailing Catamarans

There are several distinct catamaran classes, and predicting speed means understanding what the designers were building the craft to do. You might be surprised to learn that the first “modern” catamarans popped up in the New England racing circles in the late 1800s. Nat Herreshoff’s Amaryllis is particularly famous from the time .

Since then, catamarans have been synonymous with speed. But in today’s world of many different multihull designs, it’s important to set your expectations accordingly. As you would not buy a Ferrari for its cargo space, don’t expect your minivan to win any races at the track.

Examples of cruising cats include popular models made by the big-three catamaran makers—Lagoon, Fountaine Pajot, and Leopard. However, there are dozens of other companies making these boats. The market and industry for cruising catamarans have never been larger.

Most of these boats are engineered to provide comfortable accommodations for voyaging. They first became famous as vessels for sail charter holidays, where their huge cockpits and private cabins made them much more popular than the smaller and cramped monohull options.

As a result, they’re not built with high-tech components or super lightweight performance rigs. Instead, they’re the catamaran equivalent of a Hunter or a Catalina sailboat—mass-produced on an assembly line. That keeps prices lower than other types of catamarans, but it also means that they’re not winning any races. The makers use traditional layups with end-grain balsa-cored fiberglass to keep costs down. In addition, they usually feature stub fin keels, which are foolproof to sail but will not provide the upwind performance of a lift-making daggerboard.

Still, without ballast and when lightly loaded, cruising catamarans can move. They show their colors in light air when heavy displacement-hulled sailboats usually make their poorest showing. Since these moderate conditions also make for great cruising, these boats can provide a lovely ride in smooth weather.

Cruising catamarans can’t plane or anything, but their narrow hulls create an effect that means they can beat the hull speeds of a similarly sized monohull. Of course, it’s not a precise number since every boat and crew is different, but generally, you could expect speeds to be about one and a half times that of a same-sized monohull.

These catamarans are still rigged for comfort, but they’re built using the highest-quality and lightest-weight materials. While their hulls are rigged for comfortable living, they are generally designed much sleeker than regular charter-style cruising catamarans. The hulls are narrower, and you’re unlikely to see tall flybridges or forward lounge seating.

Several companies are making these boats. But in the world of catamarans, a performance cruiser is the upper end of the market. If you want a car comparison, Lagoons are something like a Chevy sedan, whereas an Outremer is like an M-series BMW. A Gunboat would be even more exotic, like a Ferrari. Not only are they more fashionable brands, but they’re also made to higher standards with cutting-edge designs .

It’s also worth noting that the category of “performance cruising cat” is a sliding scale. Some companies make vessels with better materials and craftsmanship than the cruising cats but aren’t designed for speed. Others build cats that are all about performance with few amenities.

With every new model, companies building these cutting-edge boats are attempting to boost the “performance” and the “cruising” aspect of their vessels. As a result, amenities and speed continue to get better and better.

Any racing sailboat is not designed for comfort. Especially on a catamaran, accommodations take up space and weigh the boat down. True racing vessels are designed to not worry about the crew but optimize every element for speed. Once the boat is designed for the desired performance, they’ll squeeze in bunks and storage wherever they can.

As such, there’s not much point in comparing them to liveaboard or cruising sailing vessels—they are too different. Some modern racing catamarans even fly above the water on foils. This makes for a high-speed boat and a considerable risk for sailors traveling for pleasure. Gunboat tried to make a foiling cruising cat in the G4 model, but it didn’t go so well for them.

Power cats run the same gamut of designs that sailing catamarans do. Power catamarans and sport catamarans designs are popular in powerboat circles for the same reasons they are in the sailing world–their hull designs allow for smaller underwater profiles and high speeds. There are many fast catamarans out there with twin engines and average speeds of well over 70 knots. Most recreational vessels cruise at about 20 knots, however.

Power catamarans also offer a smooth ride, making them a popular choice for large vessels like passenger ferries. There are even military vessels that use two hulls, like the stealth M80 Stiletto .

As you can see, catamaran speeds vary from just slightly better than monohulls to extraordinary flying machines. But cats are about much more than just speed. Their open and bright living space makes living aboard an entirely different experience than living on a monohull. Their cockpits flow into their salons for a full-time outdoor living feel that no other type of vessel can match. There are many reasons to choose a catamaran as a liveaboard sailboat.

How fast is a catamaran?

The answer depends on many other questions, like what sort of catamaran is it? And if it’s a sail cat, how fast is the wind blowing?

Sailing catamarans come in all different shapes and sizes. Some are optimized for living space and comfort, while others are designed with fast cruising speeds being the sole goal of the boat. The Gunboat 68, one of the fastest cruising sailboats currently made, can exceed 30 knots.

The world of power cats is much the same. Some power cats can do well over 70 knots, while most cruising boats top out at around 20 knots.

Do catamarans have a hull speed?

A hull speed is a characteristic of traditional displacement-hulled sailing vessels. The properties of the hull shape under the water create drag that limits the overall speed that the vessel can achieve. Even if you keep adding more power (or more wind), the vessel cannot exceed its designed hull speed for any length of time. Hull speed is a factor of waterline length.

Multihulls, however, have an entirely different underwater profile than monohulls. Their narrow hulls and shallow keels mean that drag is not the limiting factor. With this in mind, designers can tweak catamaran hulls to plane and cruise well above the hull speed of a similarly sized monohull.

What is the fastest cruising catamaran?

The market for fast-moving cruising cats has never seen more innovation than in the past decade. This type of boat has taken off, spurred in part by new designs and the overall popularity of multihulls for cruising. The industry leader in fast multihulls is generally considered the French-based company Gunboat . After all, one of the company’s mottos is “Life is too short to sail a slow boat.”

The company’s largest boat to date is the Gunboat 90 Sunshine . However, the delivery of the company’s current flagship, the Gunboat 68 Condor , from France to St. Maarten, provides some real-world numbers. In the delivery crew’s words, “Our max speed exceeded 30 knots a couple of times, and the max 24-hour run was 328 nm.” To save you the math, that works out for an average speed of 13.7 knots for their best day.

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.

The Cruising Catamaran Performance Debate

Which Cruising Catamaran Performs Better…And Does It Really Matter?

A client recently alerted us to a YouTube video posted by a catamaran dealer that is blatantly misleading and inaccurate. If you listen to this dealer, every catamaran manufacturer, other than the Fountaine Pajot brand, is slow, unsafe, not seaworthy and not fit to be a cruising catamaran.

While we agree that the Fountaine Pajot brand is an excellent product (we sell a lot of them), it certainly is not the ONLY good cruising catamaran in the world. There are many products available that are as good and like so many things, when it comes to choosing a cruising boat, it often boils down to personal preference, especially in this category of cruising catamaran.

2022 UPDATE: You will still find some great information below regarding cruising catamarans, especially if you are in the market to buy one. But lots has happened in the Performance Cruising Catamarans category since this post was written a few years ago, like Catana is back in the game with tons of innovation and a fresh new look. In addition to reading this article, be sure to read:

2022 Performance Cruising Catamaran Comparison
We Bought a Performance Cruiser Catana OC 50

Cruising Catamarans Performance

The dealer in the video our client mentioned to us specifically focused on the superior performance of the Fountaine Pajot compared to some of the competing brands in the cruising category like Leopard Catamarans , Nautitech Catamarans , Bali Catamarans , Lagoon Catamarans , and Catana Catamarans .

The fact is that there is very little difference in speed between similarly lengthed cats in this category. All these catamarans are displacement hulls and they pretty much sail to hull speed with intermittent surfing. Therefore, when sailed efficiently, these cats should have very similar performance.

We hear terms such as power-to-weight ratio (sail area to displacement) bandied about a lot by yacht salespeople of the various boat brands as an indicator of performance. While this is definitely a factor and certainly has an effect on acceleration and light wind performance, it is not the only factor. Some catamaran brands will be faster around the cans in a regatta while others will be better when making long passages.

What one should also consider is that when cruising is that a catamaran’s performance will be dictated by sea state as well as wind speed and direction. In light winds, there will probably be a screecher or asymmetrical spinnaker deployed and in strong winds the sails will probably be reefed. This means that in cruising mode, most sail plans are optimized to the conditions. Therefore, when evaluating a cruising catamaran’s performance, there are many factors to be taken into consideration. This is not a simple cut-and-dried argument.

Catamaran Performance Factors & Calculations

To display the different factors and calculations which are relevant when it comes to catamaran performance, we went to Multihull Dynamics for data and pulled some numbers on the two boats most mentioned in this dealer’s video, namely Lagoon and Fountaine Pajot. Here is what we found on the Multihull Dynamics site:

Base Speed – An empirically derived indicator of the speed a given boat could average over a 24-hour period (best days run) under a variety of conditions. Here again the Lagoon had better numbers with 9.82 knots versus 9.46 knots for the FP Helia 44 – this explains why the Lagoons are so successful on the long Ocean races like the ARC
KSP – Kelsail Sailing Performance number is a measure of relative speed potential of a boat. It takes into consideration Sail area, Displacement and length at Waterline. The higher the number the higher the speed predicted for the boat. Here the FP Helia 44 at 6.06 had better numbers than the Lagoon 450 which comes in at 6.02 – the Helia is the lighter boat.
TR – Texel Rating provides a handicap system for widely varying boats sailing together in a race. The formula is essentially the inverse of the Base Speed formula with constants applied to make the results useful. The Texel rating system permits the calculation of time to sail a given distance. Thus a boat with a higher TR can be expected to take longer from start to finish than a boat with a lower TR. The Lagoon 450 came in at 141 versus the FP Helia 44 at 144.
Interestingly the Leopard 45 came in with better numbers than the Lagoon and the FP as follows: Bruce number – 1.25; Base Speed 10.65; KSP 7.68 and TR 122.
The numbers for Antares PDQ44 are very similar to the Helia 44 and Lagoon 450.
Unfortunately there was no data available for the Bali or current Nautitech designs.

*Disclaimer: All data quoted here was derived from Multihull Dynamics. Catamaran Guru offers the details in good faith and does not guarantee or warrant this data.

>>Click on the pictures above or go to Multihull Dynamics website for a full explanation of the graphs.

While the Fountaine Pajot dealer touts the superior performance of their brand, actual data shows that the Lagoon brand has won more ARC cruising rallies than any other brand of cruising catamaran. These are hardly the statistics of “just a charter catamaran that sails in 50-mile circles and lacks performance”, as is claimed by this dealer. As an example, check out these ARC and ARC+ rally results in which Lagoon consistently features well:

Spirit, Lagoon 450 Flybridge – 1st Multihull
Cat’Leya, Lagoon 52 Sportop – 2nd Multihull
Sea to Sky, Lagoon 450 – 3rd Multihull
Dreamcatcher, Lagoon 52 – 4th Multihull
Sumore, Lagoon 570 – 5th Multihull
Opptur, Lagoon 500 – 6th Multihull
Lea, Lagoon 52 – 10th Multihull
2015: 380 Havhunden, first in ARC+ Multihulls Division in corrected time
2013: 620 Enigma, first in ARC+ Multihulls Division in corrected time
2012: 560 Feliz, first in ARC Multihulls Division in real time
2011: 560 Blue Ocean, first in ARC Multihulls Division in corrected time & third in ARC Multihulls Division in real time
2010: 620 Lady Boubou, first in ARC Multihulls Division & 11th overall in real time

This is NOT an indication of how good or bad one boat over another is, but rather an indication of dealer bias ! We are sure this debate will continue but it is our considered opinion that one should look at the overall boat and not be blinded by issues that might or might not be manufactured by over-zealous sales people. As we have said before, it often comes down to personal preference.

Performance Cruising Catamarans

High-performance cruising cats are becoming more popular and there are a lot more on the market than even just five years ago, but it’s not for everyone, especially if you are not a skilled sailor. Daggerboards and bigger rigs require more skill and are not for the average sailor.

We’ve been racing on and off for years on different catamarans and we’ve always had great fun sailing and surfing at speeds of 15+ knots. But as fun as that is, it can be a white knuckled, wild ride in bad conditions and can leave the crew tired and tense because one has to really pay attention. At these speeds any mistake could be catastrophic since there is so much load on the rig. So, make no mistake, sailing fast in less than good conditions is hard work, particularly when you sail shorthanded.

When only the two of us cruise along on our own boat, we really appreciate the pleasure of gliding through the water at 8-10 knots, relaxed and comfortable. Would we love to be able to coast along at a good clip in very light winds? Sure, we would love to own an Outremer or Catana! But that type of performance cat will cost us probably twice the price of a regular cruising catamaran. Is it worth the money for the average cruiser? Debatable.

With the advancement of technology, more people will eventually be able to sail these performance cats skillfully and will be able to afford them as costs come down but until such time, we believe that the average sailor can very happily sail at fair speed toward their destination, safely and relaxed on an average cruising catamaran as discussed above. The fact is, one or two knots of speed, which is what the difference between these cruising cats MIGHT be, will not make or break your passage.

2020 Update: At the time of writing this article, we owned a Lagoon 450 SporTop , not a rocket ship by any means, but a fair sailing boat. We now own a Bali 5.4 catamaran that is significantly lighter and faster in general as a cruising catamaran and we love the extra speed. However, I have to say that this boat is less comfortable underway than the heavier Lagoon. It is more buoyant, a little more skittish and tend to surf much quicker. So one has to pay more attention in more vigorous conditions. It can be tiring on a long passage, but it sure is fun!

Stephen says, “I personally like the Bali because it is a more lively boat and sails very well – when we picked our boat up in France it was completely empty and bobbed like a cork which we were not used to because our Lagoon was a much heavier boat. Since we have now equipped her with all the world cruising equipment as well as big dinghy, etc. she is a little heavier and a lot more comfortable. It is a fact that weight affects performance – the lighter the boat the better performance one can expect. We flew across the Atlantic when we were nice and light but the boat still performs well now that she is at full cruising weight”.

The Bottom Line

So, to conclude this argument, dealers are always somewhat biased about the products that they represent. Manufacturers go to great lengths and spend a lot of money training their dealer networks to be knowledgeable about their products and represent them well with the buying public. They rightfully expect loyalty from their dealers and expect them to present a positive image to the consumer. We all get that. However, when dealers trash and misrepresent their competition with manufactured issues in order to sell their own products, they do a disservice to the buying public and the industry in general.

Thanks for a sober writing. I am the owner of the Lagoon 380 Hahunden, and agter with you. I have a spreadsheet with 75 different cruising cat models and the elapsed times in 29 races, and there is not much difference in perforfance. Can send it if uou want. Greetings.

I would like to see that spreadsheet for sure!

I own a Venezia 42′ and if my boat is part of your spreadsheet I would especially love to see it! Could you please send me a copy even if it’s not on there?

To discuss performance and Lagoon or FP in the same sentence is crass. These are not performance Catamarans, purely floating caravans. They have no pretence to performance only cruising capacity, any indicator of performance is purely coincidental.

I own a Privilege 495 and wouldn’t trade it for any other cat.

Hi Jack, I am interested in the performance of your boat. I understand that mini keels decrease performance considerably. Thanks Di

I would like to point out that the data that you use from Multihull Dynamics is completely flawed due to an inaccurate displacement value. Multihull Dynamcis inexplicably lists the Helia at 14 tons, while Fountaine Pajot and your site list the boat at 10.8 tons. This is quite a big difference and skews all the metrics calculated by the site. The Helia is obviously a lighter boat and performance in catamarans starts with weight, so it is undoubted that the Helia will be more lively than the Lagoon. I totally get your point that that does not mean that it will be more comfortable. Second, on the ARC data front: my father sailed twice across the same route in the Atlantic in the last 10 years and I’m very familiar with the conditions. The trade winds there tend to be rather lively and in those conditions weight will matter less. I would expect to see different results in lighter conditions. All that said, the dealer in question is undoubtedly doing their marketing with an agenda.

Hi Ivan, thanks for your input regarding the Helia 44 weight discrepancy. We are aware of this and it holds good for both vessels. You will note that the Helia 44 shows a displacement UNLOADED of 10.8T while the Lagoon 450 shows an UNLOADED displacement of 15T. In order to get accurate performance numbers we assume that Multihull Dynamics have used a number that represents the LOADED weight of both vessels. This means that for the Helia 44 it went from 10.8T to 14.1T (an increase of 3.3T) and in the case of the Lagoon 450, it went from 15T to 20T (an increase of 5T), since it a larger boat overall with more capacity. Based on the above I think we can safely say that we are looking at a fair and accurate comparison. Your input is really appreciated and we are always open to comment and correction to ensure the information we put on the site is accurate and fair.

Thank you for the clarification on displacement.I do see that they have bumped up the Lagoon 450 displacement as well so that’s a fair comparison. I wish they published that clearly because it changes numbers quite a bit as all manufacturers typically post the weight of their boats unloaded.It looks like the Lagoon makes up for the greater weight with a bigger sail area, so that will probably add up to greater effort needed to manage those larger sails but with modern systems, all these things can be managed. Thank you for the clarification and your insight overall.

I think the misconception people have about “performance” catamarans, is that the reason sailors gravitate towards them is not their speed, it is their ability to sail in light air. If you have a catamaran that will sail at windspeed or close to it in 5-8 knots, you’ll actually sail instead of cranking up the diesel. Those true performance catamarans capable of this that also have all the creature comforts of the Helia/Elba45 or Lagoon450/46, are 50+ feet long, and twice the price unfortunately.

You are so right! Well said.

Good article! For me, the weight includes all the stuff you are taking on a month long (or longer) journey (Full fuel +extra cans, 2 sups, dive tanks and compressor, 4 cases of wine…). My opinion is that the performance cats hull design suffers more when loaded to the gills. Ride quality is also very important and is often glossed over by the performance cat advocates.

You are completely right and that was part of strategy when we raced across the Atlantic with the ARC rally. We knew that all the cats would be loaded to the max for the crossing which no doubt makes them less efficient sailing cats. Fortunately on the Bali 5.4 the buoyancy calculations is for a fully spec’d and loaded boat. So we left and sailed like a bat out of hell right off the bat and we were sailing very efficiently, making 200+ NM distances every day. We figured that as the other cats start using their fuel, water and supplies, they would sail a little more efficiently but by then we would be well ahead of the pack, and it worked. We surprised even the very fast performance cats and all the while eight of us onboard were sailing in complete comfort and were eating gourmet meals three times a day! LOL- Of course the TS’s beat us but it is hardly a fair fight. LOL

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

How is Catamaran Sailing Different from Monohull Sailing?

Sailing a catamaran is very similar to sailing a monohull in most aspects. If you learn to sail on a monohull, most of the skills are easily transferable. However, there are a couple of subtle differences that one has to be aware of:

When tacking, you must work hard to maintain your speed throughout the tack and often need to ease your mainsheet to prevent “windvaning”. Windvaning is when the larger mainsail on a catamaran tries to turn the boat back into the wind.
When gybing on a monohull, you must be very careful of an accidental gybe, and so you gybe much more slowly. On a catamaran, you can use the increased speed to your advantage and maintain speed while gybing to help depower the main.
On a monohull, as winds increase, the boat starts heeling which lets you know that you have too much sail up and it’s time to reef. On a catamaran, because they do not heel, you have to be very careful in terms of when to reef the massive main. Typically, you will throw in the first reef at 18-20 knots of wind speed (depending on the size of your vessel) and put in a second reef as the wind gets closer to 23-25 kts)

Most aspects of sailing a catamaran are very similar to a monohull, so making the transition to a sailing catamaran is usually not that challenging of a process!

Why are Catamarans Popular?

Catamarans have exploded in popularity in the last 5 years! There are many advantages to catamarans over monohulls.

Much more space on a catamaran!
Catamarans are far more stable than monohulls so they do not heel when sailing, and are less prone to rocking when at anchor. Making for a much more comfortable boat!
Catamarans have a shallow draft which allows them to enter shallower areas. In the South Pacific, most lagoons are 6-8 feet deep. This is too shallow for monohulls to enter, but a catamaran can easily enter these lagoons.
Speed: Often, especially downwind, catamarans are faster than monohulls
More light and airy living area. On a catamaran, the living space is usually up in the middle of the boat, built on the bridge deck whereas in a monohull you go down into the hull where it is darker and feels less open.
More storage space and room for extra systems like air conditioning, water makers, generators, larger fridges and freezers, etc… Again, having room for all these amenities makes for more comfortable living.

What is a Catamaran?

A catamaran is a sailboat with two hulls. These two hulls are connected by a bridge deck. Many people will be familiar with Hobie cats, small catamarans that are popular for sailing on lakes and in calmer waters. Cruising catamarans are based on this same principle but have large hulls that can fit many cabins inside, and house large structures on the bridge deck (like a galley, salon and living area).

Are catamarans safer than monohull sailboats?

Great question! Catamarans are much more stable than monohulls, and so people are less likely to fall overboard, which does make them safer in this aspect. They are larger, more stable boats, and so in most situations, this will make them a “safer” sailboat than a comparably sized monohull.

Catamarans also have the advantage of having 2 engines, which makes them “safer” when it comes to engine problems. On a monohull sailboat , if you have major engine problems you only have the option of sailing. On a catamaran, you always have a second motor ready to help out in an emergency!

Are catamarans easier to sail?

What makes monohulls harder to sail is heeling and more confined spaces. In stronger winds monohulls heel, making most tasks a little more difficult to manage. Whether you are going forward to reef, trying to winch in a sail or moving about the boat, sailing on a heeling boat is more challenging. Catamarans, however, because of their extra stability and room, allow for much easier movement around the boat as they do not heel. For this reason, catamarans are often considered “easier” to sail.

Can a catamaran cross the Atlantic?

Definitely! Early on many catamarans and trimarans were home-built from kits, and many of these boats gave catamarans a bad rap for offshore sailing. For decades now the major catamaran manufacturers have been improving these amazing vessels, and now catamarans are safe, stable and fast on offshore passages. In 2020 we completed an Atlantic crossing in our very own Never Say Never Lagoon 400S2 catamaran.

How fast does a catamaran sail?

Not all catamarans are created equal. Many of the production catamarans like Lagoon, Fountaine Pajot and Leopard are designed for cruising. This means that they are willing to sacrifice some performance in the interest of comfort for their owners and crew. These boats still are often faster than a monohull of comparable size when on a beam reach or downwind point of sail, often seeing speeds in the double digits. Upwind, catamarans do not usually have the same ability to point into the wind (as they have shorter, stubbier keels) and do not travel as quickly.

Some high-performance catamarans from manufacturers like Outremer, Gunboat and HH, make incredibly fast catamarans that can achieve speeds in the high teens and low 20s under ideal conditions.
