ON SELECTED MODELS

All models outfitted with an Foiling Package ( FCS or   Flight Control System for short ) are ready for full foiling – during your sail, specialized hydrodynamic daggerboards combined with upwards pressure make you get a controlled ‘flight’, meaning your whole boat will be above the water, rather than in it. Make alterations on the water during your flight to find the groove you are looking for and fly over water to leave others behind.

These so-called  Foil sets are designed to fly in a wide range of weather conditions, to make competitive catamaran sailing accessible to even more sailors, and are built to meet the highest safety standards. A real treat for the more, or a little less, experienced sailors.

Using the best possible manufacturing techniques available, we’ve obtained maximum strength with minimum weight using autoclave technology, curing the pre-impregnated carbon/epoxy at 120 degrees Celsius at an atmospheric pressure of 6 bar. It will put you miles ahead of any fleet in terms of performance and joy.

Nacra 17 Class

The Nacra 17 class organization is involved in every step the Olympic boat takes. After the Olympic Games in Rio de Janeiro, the class and Nacra Sailing agreed to evolve the boat to become a full foiling catamaran. The Nacra 17 class is open to any sailor with Olympic ambition.

• Hydrofoil catamarans can reach speeds of up to 40 knots (46 mph) or more, depending on the design and conditions.
• The foils on a hydrofoil catamaran can lift the hulls out of the water, reducing drag and allowing for a smoother and faster ride.
• Hydrofoil catamarans are used for various purposes, including racing, recreational sailing, and even transportation.
• Foiling on a hydrofoil catamaran requires some skill and practice, but it’s an exhilarating experience once you get the hang of it.
• Hydrofoil catamarans come in different sizes and designs, catering to different skill levels and preferences.

Hydrofoil catamarans have a fascinating history that dates back to the early 20th century. The concept of using hydrofoils to lift boats out of the water and reduce drag was first explored by Italian engineer Enrico Forlanini in the late 1800s. However, it wasn’t until the 1950s that hydrofoil technology started to gain traction in the boating world.

The first hydrofoil catamaran, known as the “Aquavion,” was developed by the French engineer René Guilbaud in the 1950s. This innovative design combined the stability of a catamaran with the lift of hydrofoils, revolutionizing the world of sailing. Since then, hydrofoil catamarans have evolved and become more advanced, offering incredible speed, maneuverability, and stability on the water.

A hydrofoil catamaran works by utilizing hydrofoils, which are wing-like structures mounted underneath the hulls of the boat. These foils generate lift as the boat gains speed, lifting the hulls out of the water and reducing drag. This lift allows the hydrofoil catamaran to achieve higher speeds and a smoother ride compared to traditional boats.

The hydrofoils on a catamaran are typically designed with a curved shape, similar to an airplane wing. This shape creates a pressure difference between the upper and lower surfaces of the foil, generating lift. The foils are usually adjustable, allowing the sailor to fine-tune the performance of the catamaran based on the sailing conditions.

To control the hydrofoil catamaran, sailors use a combination of steering and sail trim. By adjusting the angle of the foils and the sails, they can optimize the lift and balance of the boat, ensuring a stable and efficient ride. It takes some practice to master the art of foiling on a hydrofoil catamaran, but the rewards are well worth the effort.

Hydrofoil catamarans offer a range of benefits that make them a popular choice among sailors and water sports enthusiasts. Here are some of the key advantages of hydrofoil catamarans:

Speed : Hydrofoil catamarans are known for their incredible speed. By lifting the hulls out of the water, hydrofoils reduce drag and allow the boat to glide smoothly above the waves. This enables hydrofoil catamarans to reach impressive speeds, making them a thrilling choice for racing and high-performance sailing.

Maneuverability : The lift generated by hydrofoils enhances the maneuverability of catamarans. With reduced drag, hydrofoil catamarans can make sharp turns and quick maneuvers with ease. This agility is particularly useful in racing scenarios, where every second counts.

Stability : The dual-hull design of catamarans provides inherent stability, even at high speeds. When combined with hydrofoils, the stability of hydrofoil catamarans is further enhanced. This stability makes them suitable for sailors of all skill levels, from beginners to experienced professionals.

Efficiency : Hydrofoil catamarans are more efficient than traditional boats. By reducing drag, hydrofoils allow the boat to sail faster while using less power. This increased efficiency translates to longer sailing distances and reduced fuel consumption, making hydrofoil catamarans an environmentally friendly choice.

Versatility : Hydrofoil catamarans are versatile watercraft that can be used for various purposes. Whether you’re looking for a high-performance racing catamaran or a recreational sailboat for family outings, there’s a hydrofoil catamaran to suit your needs. Some models even offer the option to switch between foiling and non-foiling modes, providing flexibility on the water.

While hydrofoil catamarans offer numerous benefits, it’s important to consider their drawbacks as well. Here are a few potential downsides to keep in mind:

Cost : Hydrofoil catamarans tend to be more expensive than traditional boats. The advanced technology and materials used in their construction contribute to the higher price tag. Additionally, maintenance and repairs can also be costly, especially if specialized parts or services are required.

Learning Curve : Foiling on a hydrofoil catamaran requires some skill and practice. It can take time to learn how to control the boat effectively and maintain stability while flying above the water. Beginners may find the learning curve steep, but with dedication and proper instruction, anyone can master the art of hydrofoil catamaran sailing.

Weather Conditions : Hydrofoil catamarans are sensitive to weather conditions. While they excel in flat water and moderate winds, rough seas and strong gusts can pose challenges. It’s important to be aware of the weather forecast and choose suitable sailing conditions to ensure a safe and enjoyable experience.

Transportation and Storage : Hydrofoil catamarans can be larger and bulkier than traditional boats, making transportation and storage more challenging. Specialized trailers or racks may be required to transport the catamaran, and adequate storage space is needed to protect it when not in use.

Despite these drawbacks, the thrill and excitement of foiling on a hydrofoil catamaran outweigh the challenges for many sailing enthusiasts.

When it comes to choosing the right hydrofoil catamaran, there are several factors to consider. Here are some key points to keep in mind:

Charal: On board the radical IMOCA 60 that takes foiling to the next level

• Helen Fretter
• July 22, 2019

Charal is a next-generation foiling IMOCA 60, designed by VPLP and newly launched for solo skipper Jeremie Beyou

In St Malo for the start of the Route du Rhum in early November , every inch of the IMOCA 60 pontoons was packed with fans trying to get a close up look at the huge variety of designs taking part.

But one boat needed serious crowd control around it – Charal , the aggressively styled foiling design launched just a couple of months earlier. The scale of Charal ’s foils alone would have drawn attention, but videos of Beyou test sailing his new boat literally leaping from the water made Charal a hot topic in St Malo. We talked to designer Vincent Lauriot-Prévost of VPLP about the concepts and technology behind it.

Charal is not just the newest IMOCA 60, she marks a ‘next generation’ step for the class because she is the first IMOCA 60 designed entirely around the foils.

Most of the IMOCA 60s carrying foils in the 2016 cycle were retrofitted with them. Even those that were built anew were designed to be competitive without the foils ( Alex Thomson ’s Vendée Globe 2nd place after shearing the starboard foil less than two weeks into the race proving the sense of this policy). In truth, nobody really knew if the foils would be reliable and effective across enough of the wind ranges experienced in a round the world solo race.

“In the last edition of the Vendée we proved foils on the conventional boats, which were on boats designed for power and righting moment,” explains Vincent Lauriot-Prévost.

The results of the last Vendée Globe: 1st Banque Populaire , 2nd Hugo Boss , Maitre Coq 3rd, all VPLP-Verdier foiling designs, proved conclusively that this was the future of the class. So for Charal , VPLP took a different approach.

Why do the new Vendee Globe IMOCA 60 yachts have foils?

Foils are the newest phenomenon on the Vendée Globe race and one that looks as if it is set to…

Record fleet sets off for 40th Route du Rhum, with 40-knot conditions forecast

Along a three-mile start line off St Malo, 123 boats set off on the 40th Route du Rhum singlehanded transatlantic race…

“We have decided to make the new boat as a pure foiler. Instead of looking for a powerful hull we are looking for a less draggy hull, taking into account that the foils are going to be the element that gives the power.”

This means a big shift from trying to balance weight reduction and power, to working towards a lightweight and minimum drag hull form. One of the challenges has been that the new generation foil packages – longer foils, and casings that are stronger and more complex – come with a weight increase.

“We know that all-in the package of the new foils, including the reinforcement of the hull and so on, are just about half a tonne extra weight [over the last generation foils],” explains Lauriot-Prévost. “So how can we make the boat half a tonne lighter to compensate for this?”

Charal can be up on her foils in just 15 knots of wind. Photo: Damien Meyer / AFP / Getty Images

Hull volume has been reduced wherever possible, retaining it forward and amidships but cutting away great angular sections of bow and topsides, then sloping down to a low transom to create what Lauriot-Prévost describes as ‘a very bumpy sheer’.

Overall, the changes are significant and achieving them while remaining within the IMOCA stability rule was a challenge. “The hull is completely different. It’s a narrower waterline – we don’t want to be a cigar, but we accept to lose 15-20% of righting moment to be within the stability rule,” explains Lauriot-Prévost.

During the design process they discussed with the Charal team whether they wanted the boat to remain competitive even if they lost a foil (as did Thomson). The decision was made that the boat would not be have enough power to be seriously competitive in non-foiling mode – although it would be stable enough to be safe.

The scale of Charal ’s foils is impressive – they are wider than any other boat’s so far, with a long shaft and tip and an angled elbow. They are also surprisingly thick. The trade-off for the increased foil size and power is that they cannot both be retracted simultaneously.

The size of Charal ’s foils mean that they cannot both be raised at the same time

“We accept [we can’t] have them fully up at the same time, because we want them big. We want to create the righting moment as far out of the hull as possible, and we want a foil which creates vertical lift but which creates side force at the same time,” says Lauriot-Prévost. The shaft creates vertical force, while the oversized tip generates lateral and vertical forces.

The other key difference is that these latest generation foils have adjustable rake, using bearings fore and aft, which allow Beyou to alter the angle of attack by 5°.

How frequently the rake will be adjusted remains something to be explored but, says Lauriot-Prévost: “You can imagine maybe that instead of playing with sail sheets you play with the foil controls, and tune the boat to the reaction in the water more than the reaction of the sail forces.”

There is one significant limitation to the power even the latest generation IMOCA 60 can generate: the class-restricted rig. “There is one fuse on the boat, which is the mast,” explains Lauriot-Prévost. “The mast has been designed for [loads of] 32 tonne metres (Tm) and fully foiled, fully canted, fully raked and fully ballasted we are more 43-45Tm.”

Finding the limits

The pedestal grinder is placed right in the centre of the pit area for direct connection to winches

To monitor these loads, Charal is covered with fibreoptic sensors; five per foil with additional sensors in the foil rake adjustment bearings, as well as on the outriggers and backstay.

“During the trials it happened several times that we had alarms, because we were overloaded compared to the designed load,” says Lauriot-Prévost.

Given that potential, the adoption of the IMOCA 60 class by the Volvo Ocean Race will be a serious test of restraint. “That’s a really strong discussion that we had with the Volvo teams, because the Volvo teams have not got the same approach as a single-handed sailor, and when they push, they push!”

The other limiting factor is of course the human on board. As with any IMOCA 60, Charal has been customised around her skipper, the hugely experienced Jérémie Beyou, and his personal preferences.

“One thing which is evident on this boat is that Jérémie doesn’t want to stack the sails inside,” says Lauriot-Prévost. To make moving the sails on deck easier, there is a sloped scoop abaft the cockpit.

The cockpit is sheltered by a fixed cuddy made with Mylar film windows rather than a retractable coachroof – sliding components would be heavier. A pedestal grinder is placed under the cuddy, right in the middle of the pit.

To keep weight low all the lines coming from the bow or mast base are led through two tunnels to the pit area. The pit area has four in-line winches, directly connected to the pedestal for the easiest transmission system possible, with no gearbox or T-junctions necessary. This offers big savings in weight and complexity, but does make for a very compact working area.

“You do end up with a cockpit that is not designed for crewed sailing, at all!” points out Lauriot-Prévost. Down below was out of bounds – the inner workings of Charal’s foil controls are too new to be shared.

Many of the IMOCA skippers have talked about wearing helmets or body armour on the new foiling 60s, so extreme is the motion. Was protecting the skipper a factor in the design?

“It’s going to be the priority before the start of the Vendée,” says Lauriot-Prévost, “But Jérémie needs to find out where it is important to protect. He needs to get a bit bruised first!”

Lancé en 1950, c'est une classe qui vise les meilleures performances pour un cata de sport solo. Souvent en carbone, maintenant équipé de foils, le Classe A est ce qui se fait de mieux technologiquement pour la régate en solo. C'est une classe très dynamique et le niveau des régatiers est très (très) relevé.

Le Classe a serait l'équivalent dans l'univers du catamaran du Moth à foil : léger, technologique, extrême, rapide et qui regroupe les meilleurs de la discipline.

Le catamaran classe A, un esprit unique

Le Classe A se mène en solitaire, les libertés que donne la jauge lui ont permi d'être toujours à l'avant garde des innovations technologiques. Il en résulte un catamaran de sport à l'allure magnifique, impressionnant et performant autours de 3 bouées.

Cette gauge ouverte lui a permis d'être une des premières série de voile légère à s'équiper de foil. Les classes A volent maintenant au dessus de l'eau.

Launched in 1950, this is a class that aims for the best performance in a single-handed sport catamaran. Often made of carbon, now equipped with foils, the A-Class is the most technologically advanced class for solo racing. It is a very dynamic class and the level of the racers is very (very) high.

The Classe a would be the catamaran equivalent of the foiling Moth : light, technological, extreme, fast and bringing together the best in the discipline.

The A class catamaran, a unique spirit

The A-Class is a single-handed class, the freedom given by the gauge has allowed it to be always at the forefront of technological innovations. The result is a sports catamaran with a magnificent look, impressive and performing around 3 buoys. This open gauge allowed her to be one of the first light sail series to be equipped with foil. The A-Class now flies above the water.

Class A program

It is a boat intended more for regatta sailors than for sailors looking for "calm" rides. There are many shipyards producing A Class boats, including Marstrom, Bimare , Nacra, Addiction, Askell and DNA.

Second hand Class A catamaran

The second-hand A Classes remain quite expensive for recent productions, however, if one is looking for a catamaran for sailing more oriented towards leisure than performance: the bill will be much less expensive.

The entry prices for Class A boats are very low: sometimes 1000$ for old boats, on the other hand, recent Class A boats, those which can perform in championships, are traded for 20000$.
