  • 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.

    ALONE OFFSHORE THE WEEKLY #4 Diet.

    On Wednesday, during a radio link-up with Gitana Team, Sébastien Josse announced a water temperature of six degrees and the same for the air. Suffice to say that there’s been a chilly atmosphere of late aboard the Mono60 Edmond de Rothschild, which is presently passing offshore of the Kerguelen Islands at 46 degrees South. In these conditions, the solo sailor isn’t straying far from his ritual of two hot meals every 24-hour cycle. A precious source of energy and comfort for someone who has now been sailing for 25 days. Throughout the year and not just for the Vendée Globe, Sébastien Josse is quite heavily involved in the composition of his provisions. And to tickle his taste buds, the sailor has a choice ally: the 2-Michelin-starred chef, Julien Gatillon, who has concocted some recipes for him from the Alps and the kitchens of the gourmet restaurant, Le 1920, at the Chalet du Mont d’Arbois; a Domaine du Mont d’Arbois entity founded by Noémie de Rothschild back in 1920 in Megève

    “Food is the energy aboard,” Sébastien explains clearly, when questioned on the matter prior to his departure with a view to the video files published each week by Gitana Team (this Thursday discover: Alone around the world – The weekly #4 Diet). “I’m very interested in the food aboard. Maybe it’s because I’m greedy, but also because I can’t imagine opening a surprise food package and discovering dishes that didn’t suit my tastes. Eating well is good for morale and hence good for performance. You mustn’t take it lightly.”

    Extreme gastronomy

    It was a significant challenge for chef and skipper alike. Indeed, it was important to share their experience and their sensitivity so as to outline the flavours and the recipes that could accompany Sébastien Josse around the world. With no fridge, frying pan, saucepan or oven, just something in which to boil up desalinated sea water, the exercise becomes all the more difficult. Even in the best cookery shows, a challenge like that just doesn’t exist! “Indeed, we allowed ourselves to dehydrate Julien’s dishes. Dishes made with love and high quality produce. The smell and the taste of certain recipes will send me into raptures,” the sailor admits.

    “When we started work, Sébastien was my only guide because he’s the one who knows exactly what he’ll want to eat after several weeks at sea and what will taste good once it’s rehydrated,” Julien adds. Atop the menus currently relished by the sailor in the Southern Ocean are soups and hot dishes like risotto with morels, squid a l’Armoricaine, as well as a cod and olive oil emulsion called Brandade. “For example, we’ve accentuated the seasoning; everything’s a lot saltier or sweeter,” explains the chef, who’s just 30 years of age. “It was also important for Sébastien to have texture, to be able to bite into something and to ensure the dishes didn’t all end up being much of a muchness. After several tests and adjustments, we managed to create some dishes that appeal to him and that’s something I’m very proud about.”

    The skipper has also prepared all the rest of his supplies with nutritionist Virginie Auffret, who has experience of this rather special shopping list. After several weeks of exchanges, they reached a compromise between nutritional intake, a fondness of food and optimisation of the weight embarked. In this way, Sébastien has a relatively varied choice, with special emphasis going on the rations in the Deep South. In addition to Julien’s two dishes, the solo sailor allows himself several snacks in the day in order to have regular intakes of energy. In fact, it’s worth remembering that at these latitudes, sailors who stay awake for more or less 20 out of 24 hours, consume between 3,000 and 4,000 calories a day, which is double that of an adult back on land. 

    Cooking and offshore racing, collective adventures

    Hunting down a Michelin star entails a massive amount of teamwork, a great deal of talent and the expertise of a chef or a boss who guides the group to success. This universe is not a million miles away from the world of offshore racing and the daily life of the Gitana Team. By creating the racing stable in 2000, Ariane and Benjamin de Rothschild had an ambition to gather together professionals from top-level sailing; sailors, engineers and creative talents, they too able to reach for the stars, these though made of sea foam and technological adventure. “At 1920, I’m surrounded by a team of around thirty people. There is also the team in the dining area with whom you have to be perfectly harmonised so that everything’s impeccable,” explained Julien Gatillon, who visited Les Sables d’Olonne a few days before Sébastien set sail on the Vendée Globe. “When I’m with Gitana Team, I find that same mindset, geared towards achieving excellence, where everyone respects one another and works collectively to be the best they can be. We also work for the same family and at the heart of the same universe, which is flourishing as Ariane and Benjamin de Rothschild spur it on. The bridge that we’ve been able to build over the past few years between the sea and gastronomy has ever greater meaning here. It translates across to the teams and motivates them all the more.”
