  • 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.

    A positive outcome.

    Second overall in the Grand Prix de Marseille Métropole following on from a second place in Calvi, Gitana 11 seems to be the only crew up to destabilising Franck Cammas' leadership. But in the future, there will have to be a steadier breeze. As for Gitana X who cannot make up for her slight deficit in light air.

    Second overall in the Grand Prix de Marseille Métropole following on from a second place in Calvi, Gitana 11 seems to be the only crew up to destabilising Franck Cammas’ leadership. But in the future, there will have to be a steadier breeze. As for Gitana X who cannot make up for her slight deficit in light air.

    The Grand Prix de Marseille Métropole was a tough test for the Gitana Team. Frédéric Le Peutrec and his crew were put under pressure by Michel Desjoyeaux, Pascal Bidegorry and Armel Le Cléac’h who were clearly more on the ball in Marseille than they had been before. Gitana 11 never the less remains the only trimaran to have broken Groupama-2’s winning streak but remains at ease in stronger wind. Her second place can be put down to the crew and strategy. As for Gitana X, Thierry Duprey du Vorsent’s crew have made noticeable progress  but the weather meant that they could not really show what they were made of. The trimaran ran some fine rounds, gave the hierarchy a shaking for a few rounds, managed to clock up three rounds in sixth place and held Géant, Groupama-2, Banque Populaire, TIM-Progetto Italia off the stern before being dominated on pure speed. Encouraging.

    Thierry Duprey du Vorsent (Gitana X) :

    « This Grand Prix de Marseille confirms what we had already suspected to be the case in Nice. Gitana X finds it very difficult to hold her course if there is not much wind. A breeze of 8-12 knots is not good for us, even if we still have a fair bit to learn in terms of trim, manœuvres, and paths. The difference is too great in relation to the rest of the fleet for us to be better placed than we are. For all we manage to do some good stuff out on the course, we cannot put up a fight over two rounds – much less so on three in a windward leeward course. But we have not lost heart – we just need more wind. We’ll keep working on crew manoeuvres and paths, and picking up speed after rounding the marks. On the tactics front, it was hard-going as there were lots of compulsory sections which put paid to any initiative. Our starts were pretty good on the whole, well placed but not fast enough. That was a real handicap for us against the others who are much faster off the mark. The last two legs on Sunday gave us the chance to gain ground on Banque Populaire and TIM-Progetto Italia downwind which is encouraging. But this really is a tough wind range for Gitana X. There is still room for progress when it comes to communication in-house so that everything runs more smoothly and fits together better. The arrival of Jochen Krauth who had previously sailed on Bayer with Frédéric Le Peutrec then on Sodebo with Thomas Coville, brought more serenity overall and lots of individual progress has been made. We returned to La Ciotat on Monday and I’ll be setting out for Vigo with Mayeul Riffet (stand-in crew) on a qualifying passage for the Jacques Vabre two-handed transatlantic race. Erwan Le Roux will be using this time to do a weather course with Sylvain Mondon. »

    Frédéric Le Peutrec (Gitana 11) :

    « All in all, we have every reason to be happy even if the second place in Marseille is not quite the second place that we had in Calvi ! In Corsica, we clocked up five second places in a row from the start and the outcome was already decided before the last day in light air. The battle here was much more intense although Groupama-2 remains almost untouchable in light air. We had a hard time hitting second against Géant, Banque Populaire and Foncia who play a much more incisive game than before. The crews are getting the feel of their machines now and the changes made over the winter shed sessions have made them increasingly competitive, particularly when there is not much wind. Gitana 11 really sails fast as soon as the central hull is out of the water, in more than 10 knots of wind. In all situations, even the most complex ones, we managed to score a few points, even in the last round which was capital as we had to be ahead of Géant if we were to hang onto out second place overall. We never let up and right through to the very end, we held him off, pipping him at the post ! The coastal race was not easy. We lost a rudder in the fifth round which obviously meant that we were second but we had fought very hard. Vigo is going to be anyone’s game. The newcomers (Quiblier, Souben) have fitted in really well. Yann Guichard, back from the Tornado Worlds (5th), raced really well on this course which is particularly tricky. On Tuesday, I’m setting out with Yann Guichard on a qualifying passage to La Trinité sur Mer for the Transat Jacques Vabre. It should take us a week or so and we’ll be getting underway on Saturday once again to rally Vigo for the Grand Prix (15th-17th July). »
