  • 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.

    Great final for the Gitana Team.

    By winning a round in the 11th Grand Prix du Port de Fécamp with panache, Gitana 11 demonstrates that with a little bit of wind, she is the unchallenged leader of the circuit. In spite of conditions which are not really optimum for Gitana X, she too managed to sail a nice round finishing fourth.

    By winning a round in the 11th Grand Prix du Port de Fécamp with panache, Gitana 11 demonstrates that with a little bit of wind, she is the unchallenged leader of the circuit. In spite of conditions which are not really optimum for Gitana X, she too managed to sail a nice round finishing fourth.

    The Gitana Team knows that when the wind is under 5 knots, they cannot come close to the other tris. They cannot be sailed as close to the wind as the other boats, and glide less efficiently downwind. The starts were that much tougher as a result, idem the tactical choices upwind and the controls downwind. In spite of everything, a bit like in Marseille, Frédéric Le Peutrec and his crew showed that they could worry the untouchable Groupama-2, which is particularly at ease in fickle conditions and light winds. Gitana 11 is now the only boat to have win a round against Groupama-2 !

    In the 7th round on Sunday afternoon, Gitana 11 won with elegance. Franck Cammas had a clear lead when Frédéric Le Peutrec was fourth. Cammas headed off on the wrong side of the course on the last upwind leg to mark his direct opponents, Pascal Bidégorry and Michel Desjoyeaux. Just what the doctor ordered as this played right into the hands of Gitana 11 who set out in search of a wind shift out to sea after a rain cloud had blown over. The Rothschild trimaran changed tack in good wind pressure as the others were having a hard time in a no wind zone. Frédéric Le Peutrec and his crew of 9 rolled round the mark slightly ahead of Pascal Bidégorry and Franck Cammas. On the run downwind, with the gennaker up, Gitana 11 flew down to the finishing line to win the round !

    Gitana X did likewise on a windward leeward loop on Satruday in extremely light air which seemed to screw the boats in place. Thierry Duprey du Vorsent and his crew found the Achilles heel and found themselves racing against the opponents and back to within spitting distance of the three leaders, particularly ahead of Michel Desjoyeaux and Frédéric Le Peutrec. He crossed the line at a snail’s speed, but holding onto his place never the less !

    The Gitana Team is not over the moon with the final result but are pleased to see that both crews devoted all their energy to making up for the speed deficit in such fickle conditions. A simple hair’s breadth, a second catastrophic round was enough and Gitana 11 struck a mark caught up in the down thrust from a helicopter to finish last. Think positive – Yann Guichard (Gitana 11) and Erwan Le Roux (Gitana X) did the best they could and the Gitana Team is still highly motivated. Rendez-vous in Lorient at the end of the month for the last Grand Prix of the season. Could be in for a tough battle.

    In the world of sailing, the name Gitana is inseparable from the French-Swiss branch of the Rothschild family. It conjures up century old images of a particular lifestyle where passion, team spirit and the quest for excellence come together. Under the aegis of the Baron Benjamin de Rothschild, the Gitana history turned to multihulls in 2000 when the Gitana IX entered the Transat Québec /Saint-Malo. For the second year in a row, the Baron has entered two trimarans – Gitana X and Gitana 11 – in the ORMA Championship. The Gitana X, is devoted to the training of young talent and the objective for Gitana 11 is excellent performance at the top level. Tradition, innovation and transmission…
