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.

WATCH: How do the F50 foils work?

SailGP’s high speed, foiling F50 is the culmination of 10 years of development in high performance, multi-hull racing.

The F50's cutting edge technology is evident in its status as the first boat to hit 99.94 km/h during racing - and it has a top speed of over 100 km/h.

But how does the F50 fly above the water and how to teams work together to get as much speed out of the boat as possible? The F50 foils using rudders with elevators and two daggerboards for a fast and stable flight.

The boards are constructed with higher modulus carbon fiber for less resistance at high speeds.

A number of technical innovations work to reduce the onset of cavitation - which occurs when the reduction of water pressure ‘boils’ the water around the foils - creating air bubbles which increase drag and reduce lift.

Teams must therefore work together to fly as high as possible without flying too high and crashing into the water, rising speed and losing speed in SailGP’s high pressure racing.

Eagle Class 53: The foiling cruiser inspired by the America’s Cup

• Matthew Sheahan
• August 6, 2019

Is this the future of sailing? The Eagle Class 53 is a wingmasted cruising catamaran designed to fly on T-foils

Not everything that flies is destined to scorch around an America’s Cup course. The future for sailing hydrofoils is surely about more than just racing. At least, that was the view of one owner who, having witnessed the America’s Cup foiling catamarans, saw a big opportunity.

“I’ve worked as a skipper for yacht owner Donald Sussman for 16 years,” says Tommy Gonzalez. “When he saw the foiling Cup boats he knew that this was what he wanted to have a go at. He is not interested in racing himself, he wanted to go cruising, but cruising on foils. He saw what had been created and believed that this had practical potential. Put simply he said: ‘I want one and I want to be the first.’”

As well as being a professional skipper, Gonzalez is the president of Fast Forward Composites, a Rhode Island-based composite building facility where the Eagle Class 53 was constructed. Understandably, the road to creating such an ambitious cruiser was never going to be straightforward. So the plan was structured around several key elements and stages, starting with an efficient and easily managed wingmast.

The hybrid solid wing and soft sail configuration means the rotating rig can be reefed. The entire solid wing can be rotated through 360° ensuring the rig can always be fully depowered – important for docking and close quarters manoeuvring

Of those two criteria, efficiency is easy to satisfy – wingmasts are by definition more efficient. It is the practicalities of handling them that usually causes problems. Reducing sail in breezy conditions and leaving the wing up at the dock are two of the biggest issues.

The solution on the Eagle Class 53 was to create a composite wingmast where 50% of the area is a solid D-section and the trailing 50% a soft sail that can be raised, lowered and reefed. Interestingly, it is a similar concept to that of the next generation of 75ft foiling monohull Cup boats, currently under development. “The rig is a little lighter than a conventional mast and sail set up, and significantly easier to handle,” explains Gonzalez.

“Because the sail can be raised or lowered we can reef the main, or even just sail with the solid section. The mainsheet loads are around 40% less than a conventional rig and because the sail can turn 360° we can let the wingmast fully rotate, which makes life simple when you’re docking. You just let it feather.

“In addition, because we have a part soft sail, which we have developed with North Sails, we can create twist which allows us to de-power the top of the sail, so we have plenty of control over this wing and the advantages that go with it.”

Baltic 142: The superyacht bringing foiling technology into cruising

The Baltic 142 may not be using the hydrofoils popularised by the America’s Cup, but her 29ft 6in long (9m)…

The next stage was to work towards foiling. To do this the team decided to create a cat that had C-section daggerboards that would help reduce displacement at speed but not lift the boat entirely. Getting used to controlling the power and feeling the behaviour of the boat through various wind ranges and sea states would provide a solid understanding of the boat’s characteristics.

“Once we have got used to the way the boat handles, the next stage will be to fit T-foil rudders which will take us onto the next level,” continues Gonzalez. “With these we will be able to get used to the software system, the instrument displays and the feel and the control of that part of the programme without taking the boat to full flight.

“That will allow us to get her up on her toes like a ballerina and keep her there so we understand what she feels like before she flies. “After that, in the spring next year, we’ll remove the C-foils, put on the T-foil daggerboards with their elevators, and move on to full foiling.”

The wingmast has a solid D-section and trailing soft sail

The proposed T-foil daggerboards will be angled out which makes the overall platform slightly wider, which in turn makes for more stable and efficient foils. And while improving the efficiency of the lifting surfaces, the outward bend in the daggerboards will also help to generate more righting moment, and hence achieve greater stability.

The control system itself will be a form of fly-by-wire system that will allow autonomous flight to ensure that the boat sails within safe operating limits. “If you have some of the gods of sailing aboard you will be able to override the controls to some degree, but under normal circumstances the control system will automatically de-power and lower the boat back into the water when the speed gets to 35 knots,” he explains.

So far the project has gone well. After the boat was launched earlier this year she cruised in the Caribbean during the regatta season before heading north back to Bristol, Rhode Island. “We’ve been very pleased with how well the boat sails and how easy she is to handle,” said Gonzalez.

“When we’re on delivery trips we have just three aboard. Aside from myself, the other two crew are not highly qualified professional sailors and yet we are looking at boat speeds of around 15-18 knots upwind and then 22 knots off the wind.

“We have also been through a squall of 35 knots where we were sailing with just the D-section of the wing mast which was easy to control by feathering the wing. When we get to the foiling stage we anticipate that we will be able to fly in around 10 knots true.”

The Eagle Class 53’s roots lie firmly with the foiling America’s Cup catamarans. Even in displacement mode she’s an exhilarating ride. The goal is to achieve fully foiling performance

It is still early days for a project that Gonzalez describes as being “crawling before walking, before running and ultimately sprinting”, once the hydrofoils are fitted.

Yet during the development process it has become clear that there are others who are interested in the 53-footer, whether it foils or not. So, while the next big goal is to work towards building a 75-80ft long distance cruiser, currently called the 8X, interest in the Eagle Class 53 has been sufficient for the company to tool up for a limited production run.

“We have created carbon tooling for the 53 and are looking to build around seven of them,” said Gonzalez. “For the 8X, we are hoping to build three with the first being available during the winter of 2021-22.”

Gonzalez is a realist when it comes to the future. “As we all know, foiling has been around for a long time in military and public transportation, so we need to set an example to insurance companies and the likes that we are foiling safely and encourage others to follow. But the time has come. This is part of the evolution of our sport.”

[2023] Hydrofoil Yacht: The Ultimate Guide to Sailing on Foils

• November 1, 2023
• Hydrofoil Basics

Quick Answer: A hydrofoil yacht is a sailboat equipped with wing-like foils that lift the hull out of the water as it gains speed. This reduces drag, increases speed, and provides a smoother ride. Hydrofoil yachts can be retrofitted on both monohull and multihull sailboats, with different types of foils used for stability and control.

Welcome to Hydrofoiling™, where we bring you all the latest and greatest information about hydrofoil boarding. In this comprehensive guide, we’ll dive into the world of hydrofoil yachts, exploring their history, configurations, classes, and more. Whether you’re a seasoned sailor or a curious beginner, this article will provide you with expert advice and insights into the exciting world of hydrofoil yachts.

A hydrofoil yacht is a sailboat equipped with wing-like foils that lift the hull out of the water as it gains speed. This lifting action reduces the wetted area of the hull, minimizing drag and allowing the yacht to achieve higher speeds. Hydrofoil yachts can be retrofitted on both monohull and multihull sailboats, with different types of foils used for stability and control.

• Hydrofoil yachts use foils to lift the hull out of the water, reducing drag and increasing speed.
• Different types of foils, such as T foils, C foils, S foils, and L foils, are used for stability and control.
• Hydrofoil yachts can be retrofitted on both monohull and multihull sailboats.
• The International Moth class is one of the most widespread uses of hydrofoils in sailboats.
• Hydrofoil yachts can achieve impressive speeds, with some reaching over 50 knots.

Hydrofoil technology has been around for over a century, with the first patent for a hydrofoil boat filed in 1898 by Italian engineer Enrico Forlanini. Since then, hydrofoil yachts have undergone significant advancements, transforming the sailing experience and pushing the boundaries of speed and performance.

The concept behind hydrofoil yachts is simple yet ingenious. By using wing-like foils mounted under the hull, these yachts can lift themselves out of the water as they gain speed. This lifting action reduces the wetted area of the hull, minimizing drag and allowing the yacht to glide effortlessly through the water.

Hydrofoil yachts come in various configurations, each designed to optimize performance and stability. Let’s explore some of the most common types of hydrofoil yachts:

Monohull Hydrofoil Yachts : Monohull hydrofoil yachts feature a single hull and employ a “ladder” arrangement of hydrofoils. These hydrofoils typically have a dihedral angle of around 50 degrees and are complemented by a stabilizing rudder foil. This configuration provides stability and control, allowing the yacht to sail smoothly on foils.

Multihull Hydrofoil Yachts : Multihull hydrofoil yachts, such as catamarans and trimarans, offer increased stability and performance. These yachts use wider planforms, allowing for greater lift and control. Some multihulls utilize three foils, with two main forward foils providing lift and a horizontal foil on the rudder for additional control.

Hydrofoil Catamarans : Hydrofoil catamarans, also known as foilcats, combine the stability of a catamaran with the speed and efficiency of hydrofoils. These yachts can achieve impressive speeds while maintaining excellent stability, making them popular choices for racing and recreational sailing.

Hydrofoil technology has found its way into various sailing classes, revolutionizing the way we sail. Let’s take a closer look at some of the notable hydrofoil classes:

International Moth : The International Moth class is one of the most widespread uses of hydrofoils in sailboats. These single-handed dinghies feature foiling capabilities, allowing sailors to achieve incredible speeds and maneuverability. The class has seen rapid growth since 2001, with carbon fiber foils and advanced design techniques pushing the boundaries of performance.

Waszp : The Waszp class is similar to the International Moth class but utilizes aluminum foils instead of carbon fiber. This makes the Waszp more accessible to a wider range of sailors while still providing the exhilaration of foiling.
