  • 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.

    Training gets underway again.

    After an Easter weekend devoted to the Spi Ouest France, training is underway again for both Gitana multihulls - Thierry Duprey and his crew on Gitana X in La Trinité/Mer and Fred Le Peutrec on Gitana 11 in Port La Forêt.

    After an Easter weekend devoted to the Spi Ouest France, training is underway again for both Gitana multihulls – Thierry Duprey and his crew on Gitana X in La Trinité/Mer and Fred Le Peutrec on Gitana 11 in Port La Forêt.

    Since the boats were re-launched in mid-March after their winter refit, both Gitana were able to validate the modifications carried out throughout the winter months with a view to optimising the boats for the new ORMA season. And a heavy programme it is too, with two ocean races, five Grand Prix and several complementary events (Trophée SNSM from Saint-Nazaire to Saint Malo in mid-April, Giraglia from Saint-Tropez to Genoa in mid-June and the Défi Petit Navire in Douarnenez at the end of August). Gitana X will be sailing in the Bay of Quiberon from Tuesday until Friday with her 11-strong Grand Prix crew on board, with the exception of Mayeul Riffet who is on a weather training course in Paris. Together with Sylvain Mondon, Mayeul will be taking care of routing for the Transat Jacques Vabre in November. Thierry Duprey and fellow crew member Erwan Le Roux shall be leaving next week to carry out their qualifying passage in view of this race from Le Havre to Salvador de Bahia. The pair will be covering the 2 000 nautical mile long passage in race configuration off the coast of Brittany. Mayeul Riffet and Sylvain Mondon will be providing strategy and weather support from ashore.

    In Port La Forêt, Gitana 11 will have three other trimarans to pit herself against throughout the week as her crew get down to training once again and validate the optimising transformations made to their steed over the winter. There should be a clear improvement in her speed potential. Géant (Michel Desjoyeaux), Groupama-2 (Franck Cammas) and Banque Populaire-4 (Pascal Bidegorry) will be sailing the same waters. Crew configuration for Fred Le Peutrec will be almost identical to the final Grand Prix version –  Jean-Baptiste Levaillant is being replaced by Franck Citeau who will come and back the team up at the end of the season, and the Baron Benjamin de Rothschild will be surrendering his place for this training session to the Gitana Team coach, Philippe Neiras. A busy programme headed up by Christian Le Pape and Loïc Ponceau from the Port La Forêt Training Centre. The comparison of Gitana 11’s speed potential with three of her Multihull World Championship competitors will be extremely enriching. Both Gitana will be together off Belle-Île on Friday for a photo and video shoot. 

    As for the Spi Ouest France, the result is mitigated for the Gitana Team, but it must be emphasised that the level was particularly high with twenty Open 7.50 lined up on the start for five rounds in a medium breeze and one race in light air. Both Gitana seemed to lack speed in moderate conditions and in spite of one or two good tactical moves, neither ever really threatened the leaders. It should never the less be pointed out that Caroline Vieille, the only woman crew member on the ORMA 2005 circuit who is on Gitana-10, was bowman on Adonnante.com (2nd in the Spi Ouest France with Nicolas Groleau at the helm), that Antoine Mermod, trimmer on Gitana 11 and in charge of research and development for the Gitana Team, was on Jaouen-Bostik (3rd in the Spi Ouest France with Charles Caudrelier at the helm) and that Alex Marmorat, winchman on Gitana X supported Marc Guillemot on Vecteur Plus (5th in the Spi Ouest France).
