  • 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.

    Aboard the Multi70 Edmond de Rothschild it’s all about adjustments: adjustment of the sails, adjustment of the automatic pilot, as well as adjustment of the skipper. For Sébastien Josse, this adjustment is not about blocks or lines, but rather having a balanced, nutritious diet, which has to be both practical and comforting. Thanks to the complicity and talent of Julien Gatillon the Michelin-starred chef of the 1920 (Domaine du Mont d’Arbois, Megève), the skipper of the Gitana Team will be able to treat himself to a star-studded transatlantic race.

    Risotto with chanterelle mushrooms, chicken breast stuffed with onions, veal in white sauce, marinated salmon, vegetable soups, rice pudding, fruit cakes… It’s a far cry from the freeze-dried dishes, which means food that is dehydrated and reduced down to a powder, that sailors usually carry aboard on transatlantic and round the world races.

    Equipped with a single stove and a kettle, Sébastien Josse has neither the utensils nor the time to get embroiled in a heavy cooking session aboard the Multi70 Edmond de Rothschild. In order to get the measure of what awaits the skipper of the Multi70 Edmond de Rothschild and create an array of dishes adapted to the living conditions his steed and the race pace impose on him, Julien Gatillon exchanged his chef’s hat for boots and a set of foulies during a day’s sailing offshore of Lorient. This outing brought about a set of dishes cooked up by the chef of the 1920 and his group, which are preparing to traverse the Atlantic. Devised and prepared on the hills of the resort of Megève, in the same way as the dishes he presents in the Michelin-starred restaurant of Le Chalet du Mont d’Arbois, the meals are specially vacuum-packed as close to the date of departure from Saint Malo as possible so that Sébastien will be able to feast on them for a few days despite not having a fridge aboard.

    At sea, the skipper of Edmond de Rothschild consumes around 4,000 calories a day, which equates to double the average daily intake by an adult. This important nutritional need compensates for the physical effort of this top-level athlete as well as a multitude of minor energy-guzzling details, such as the constant battle to remain balanced in line with the motion of the boat, the reduced and often poor quality sleep phases and also the seasickness that can strike in the first few days at sea. A vital need and a competitive factor, meals are also an opportunity to take a well-earned rest and relax for a few minutes: “When racing, I don’t have a set rhythm to my meals, but I have to have a regular supply of food that is rich in calories to match up to the physical effort required to drive a trimaran like Edmond de Rothschild. It’s not always easy or even pleasant to eat, particularly when you’re in very heavy seas, but it’s essential for performance. As such, it’s more of a need. As a result, I’m lucky that I can take dishes with me such as those cooked by Julien Gatillon, because being able to enjoy real flavours will give me a few moments of important respite during the race” admits Sébastien Josse.
