  • Retractable Y-shaped foils, adjustable in three dimensions

    Inspired by the appendages of the America's Cup foiling monohulls, these Y-shaped foils have a wingspan of over 5 metres. They are designed to generate powerful lift, increase power and offer a wide range of adjustments to optimise flight at every point of sail and in all conditions. Beyond their impressive size, these foils feature many unique innovations.

    Revolutionary U-shaped rudders

    These are probably the most visually striking innovations on the new Maxi Edmond de Rothschild. To fly high above rough seas while maintaining control, the team wanted very long rudders that would remain in contact with the water. The challenge is that longer rudders tend to flex under load, severely affecting steering and the efficiency of their lifting surfaces. A new geometry was needed to give these appendages maximum stiffness, resist cavitation and ultimately improve control of the boat and make better use of its power. The result is a set of U-shaped rudders over 4 metres long, a metre longer than those on Gitana 17. Their shape, reminiscent of a tripod or an inverted π, is only the visible part of what makes them so distinctive.

    A daggerboard optimised to stabilise the boat and limit cavitation

    With its wide span, the daggerboard resembles an aircraft tail assembly, with two adjustable flaps: one on the vertical section and the other on the horizontal section, the distinctive “manta-ray wing”. On Gitana 18, the innovation is to position this wing behind the vertical part of the appendage, rather than directly beneath it, to minimise flow disturbance and cavitation.

    Rig: adjustable spreaders to control mainsail power while sailing

    Gitana 18’s mast is 1.50 metres taller than its predecessor’s. The boom is also shorter, creating a more slender sail plan. The major innovation is a set of spreaders that can be adjusted while sailing to bend the mast fore and aft. Actuated by hydraulic rams, these spreaders can pivot through 35 degrees to adjust the bend in the middle of the mast. This unprecedented system allows the sailor to control mainsail power: adding depth in light winds to take off sooner, or flattening the sail to reduce power at high speed or in strong winds. Adjusting the depth, and therefore the power, of the mainsail can also save a solo sailor time and energy by reducing the need for risky manoeuvres or headsail changes.

    Central hull:
    an integrated, structural coachroof

    The naval architects and Gitana design team wanted an exceptionally stiff, structurally robust platform. This applies both to the floats, which must withstand heavy loads from the foils and rudders, and to the central hull, which is subject to torsion. The enclosed coachroof is integrated into the hull and contributes to its structural strength. Inside, the cockpit brings all sail-handling controls together, with ergonomics shaped by many hours of design and development. The coachroof also stands out for the number and size of its windows. This configuration meets the visibility requirements of the Ultim class rules and gives sailors the best possible view to keep a visual watch.

    For the past 20 years, the Transat Jacques Vabre has gathered together the elite of ocean racing. Setting sail every two years, this event for monohulls and multihulls has seen numerous sailors step up to the challenge! This 11th edition will be the third participation for Sébastien Josse and the fourth for his co-skipper Charles Caudrelier a little journey back in time for any interested parties!

    The locals in Le Havre have always known how to give sailors a warm welcome, especially at the heart of the Bassin Paul Vatine, where those competing in the Transat Jacques Vabre build up their first memories of the race, or rather the pre-race atmosphere. As the autumn depressions sweep across the French coast, the beginners and the more experienced sailors exchange ideas, examine the grib files and try to solve the world’s problems. Everyone will remember these moments because a Transat Jacques Vabre has a significant bearing in a sailor’s life.

    The discovery

    His first participation has a special place in the heart of the skipper of the MOD70 Edmond de Rothschild. “It was in 2003, a year before my first Vendée Globe,” Sébastien recalls. “I’d just taken over the monohull VMI. My aim was to learn to helm an Imoca singlehanded and I was lucky enough to have alongside me Isabelle Autissier, whose career path on the subject is exemplary. I had left the Figaro circuit burning with enthusiasm. I thought you could hoist a spinnaker in five minutes…! Isabelle taught me a great deal, particularly in terms of the weather and the special handling required on these boats.”

    Charles made his grand entrance onto the Transat Jacques Vabre scene back in 2005. The services of the recent winner of the Solitaire du Figaro were then sought by Yvan Bourgnon, who needed someone to second him aboard the 60-foot Orma trimaran Brossard. “I sailed on the boat for a year with a nice crew. We were leading the way in the Orma class at the time. It was great and I felt a great sense of pride doing it. Unfortunately the boat broke in two on exiting the English Channel and the adventure ended there.” 

    The best memory

    In 2007, Charles returned to the scene with a monohull this time, teaming up with Marc Guillemot aboard the 60-foot Imoca, Safran. “I was lucky to be part of a very fine team with a very high-performance boat. We dominated the start of the race and, following a light patch in the middle we finished second, less than an hour astern of Michel Desjoyeaux. It’s one of my best racing memories.”

    A humdinger of an edition

    In November 2009, the storm raged offshore of the Bay of Biscay. To make Puerto Limon on the Caribbean coast of Costa Rica, some opted to adopt a northerly route and tackle the depression head-on. Among them Safran boasted the Guillemot-Caudrelier pairing at her helm once again. They were followed by Kito de Pavant and François Gabart (Groupe Bel), as well as Sébastien Josse and Jean-François Cuzon (BT). In furious seas, the roof of the monohull BT broke under the force of the waves. The boat began taking on water and the sailors were airlifted to safety by helicopter. It’s still a painful memory for Sébastien.

    Further to the West, Safran came out of the gale at the front of the pack. “The challenge of this option was to come out the other side. We quickly felt that we had control of the race, but we were afraid of breaking the boat and losing everything,” Charles admits. “Groupe Bel was pushing hard behind and we were under pressure right the way to the finish line. It really was a fine victory. I remember it being a tough race but a superb experience.”

    With just days to go until the start of the 2013 edition, Sébastien Josse and Charles Caudrelier still feel a bit like rookies despite all that has gone before. Indeed, aboard the multihull fitted out by Baron Benjamin de Rothschild, the two men are tackling their very first transatlantic race aboard a multihull. A sizeable challenge awaits them, on what will be a demanding course as far as Itajaí, Brazil, with a flood of new memories to rack up along the way!
