  • 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.

    There was an air of deliverance this Thursday at 1300 hours offshore of Le Havre. After having to sit it out for some days due to the rather blustery autumnal weather, the entire Transat Jacques Vabre fleet set sail today. Not far from the cliffs of Sainte-Adresse, the forty-four duos competing in this 11th edition finally set off for Itajaí in Brazil. There was a drizzly atmosphere, with low cloud and a light westerly breeze, which barely exceeded 8 knots. Not the perfect scenario but the sailors, keen to get going, wouldn’t have traded places for all the world. The author of a great start at the pin end of the line, the trimaran fitted out by Baron Benjamin de Rothschild quickly gained control of the fleet and went on ahead once she was around the Radio France mark, situated some 3 nautical miles from the start line. For Sébastien Josse and Charles Caudrelier, the first few hours of racing and the exit from the English Channel promise to be tactical with the wind set to build and conditions likely to be boisterous as they traverse the Bay of Biscay.
    Le Havre to Cape Finisterre, tight timing

    “I’m confident!” gushed Sébastien Josse just minutes before leaving the Bassin Paul Vatine. “The boat has been prepared to perfection by the members of Gitana Team and Charles and I have done what was needed in terms of sea trials and training sessions. The weather conditions over the first few hours will enable us to gently get into our stride with the race, even though they’ll be highly tactical as there are some moves to be pulled in the English Channel,” explained the skipper of Edmond de Rothschild. 

    Rain, light airs, upwind conditions and current: such will be the menu for the initial hours at sea for the Edmond de Rothschild duo: “It’s going to be pretty light at the start and during our exit from the Channel in general. There are a certain number of manœuvres on the cards and we’re going to have to skilfully negotiate the numerous zones of current. I think it’s going to be complicated as there are sure to be fairly heavy seas left over from last night’s storm,” Charles Caudrelier told us. However, once they’re around the north-west tip of Brittany, the atmosphere will very quickly change aboard the 70-foot trimarans: “the wind will gradually increase as we approach Ushant because we’re going to pass what we call a cold front and at that point the wind is set to build significantly: from 15, it will shoot up to 25-30 knots with the gusts. The negotiation of the Bay of Biscay is likely to involve a beat, though we won’t be hard on the wind, and conditions are forecast to be boisterous with a big 4 to 5-metre swell. That will be the tricky section for the start to the race,” admitted the skipper of Edmond de Rothschild. 

    Given the weather situation forecast, the two sailors know that the miles which separate Le Havre from Cape Finisterre, to the extreme North-West of Spain, won’t be at all restful: “Charles and I are readying ourselves for very little sleep until we’re around Cape Finisterre. This first stage of the race is very important and there’s a set timing to be adhered to. The later we get to Cape Finisterre the more unfavourable the conditions will be with the arrival of a very deep depression over the Bay of Biscay. As such we’re really going to have to pull out all the stops over the first 500 miles of this transatlantic race. Every hour gained until we reach the tip of Spain will benefit us over the next stage of the course. Once we’re around Cape Finisterre we’ll be able to breathe and a whole new race will begin,” Sébastien Josse explained. “Heading the fleet at that point would be a real bonus for the next stage”, the co-skipper adds.

    A double-handed transatlantic race, a very rich human experience

    Particularly focused when the trimaran fitted out by Baron Benjamin de Rothschild cast off, Charles Caudrelier didn’t disguise his emotion as he headed off on his ‘debut’: “I’m very happy to be going as we’ve been waiting for this moment for quite some time. I feel good now and I feel prepared, but inevitably that’s coloured by stress. It’s our first double-handed transatlantic race in a multihull!” With complementary characters at sea, the Josse – Caudrelier duo has proven to be very close on land. Displaying immense mutual respect for one another and a solid amount of experience, today the two sailors have what it takes to write a great story in this race: “Sébastien and I have known each other for a long time, but we’ve really strengthened those ties this year, both on the boat and on land, and I’m really happy to be sailing with him in this race. I know that it’s a very emotional experience to race these boats and it’s going to be nice to share that with him. We’re keen to write a great story together,” concluded the co-skipper of Edmond de Rothschild.

    At the first official polling at 1600 GMT, Edmond de Rothschild was still leading the way off the Cotentin headland. Already the hand-to-hand battle with Oman Air-Musandam seemed to be on. Indeed the two one-design trimarans were just a hundred metres or so apart.
