  • 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.

    Gitana Team Manager Yann Marilley also crews on Gitana 11 as trimmer. Looking back over the 2004 season he sets out the objectives for the two trimarans entered in the ORMA Multihull World Championship.

    « Last season’s results were a little mixed. Entering two boats on this circuit is a major undertaking in its own right. All of the problems linked to logistics and setting up assistance teams ashore had to be resolved. The experience and skill of Gitana X’s skipper, Marc Guillemot added a lot to the project. He contributed to improving the boat’s previously lacklustre performance. Although we could not realistically expect her to win a Grand Prix, he played the game and did manage to upset fellow competitors out on the course. The main aim was The Transat, the single-handed race from Plymouth to Boston. Unfortunately he broke a dagger board the very first night. That was tough to take as Marc was up to taking one of the top three places, even winning the race. He adapted to the boat well. Marc is without any doubt the most experienced solo yachtsman on this type of boat.
    For Gitana 11, the main aim was a Grand Prix win. Fred Le Peutrec’s goal on The Transat was to gain single-handed race experience for the Route du Rhum 2006 and to make it across the Atlantic in a decent place – which he did. The Québec-Saint Malo race did not end quite so favourably for Fred who had to withdraw following a violent collision with a non-identified floating object at a time when the boat was in the « top 3 ». Later on in the season though, she won the Grand Prix de Calvi and made it onto the podium in Fécamp and Marseille. Which demonstrates that the Gitana Team features in the best three teams on the ORMA circuit. In 2004, we were also able to create a close-knit technical team which is our major asset.

    Winning in the firing line

    For 2005, both boats will be competing on the ORMA circuit. Gitana X is now in the hands of Thierry Duprey, formerly Gitana X’s boat-captain and skipper of Gitana 9. Mr de Rothschild has decided to chose young sailors with an average age of 25 and to trian them in the art of racing 60-foot multihulls. Thierry’s job will be to develop that sector as best he can right across the board throughout the events on the 2005 calendar. The major goal is the Transat Jacques Vabre. Both the boat and the Thierry Duprey-Erwan Le Roux team can expect to do well in that race. All the more so given the gigantic work which has been put in during the trimaran’s winter refit. More than 7 000 hours of labour have been spent working on Gitana X in her shed in Saint Philibert. All done in-house by the Gitana Team and not outsourced to a shipyard for reasons of economy and speed. The team has made a great effort to make the boat lighter, shedding some 250 kg, the equivalent of three crew in a Grand Prix !
    As for Gitana 11, hardly any changes have been made to her technical team. Following the end of year analysis pinpointing her weaker points, the trimaran went into the CDK Technologies shipyard in Port-La-Forêt for her winter refit. The solutions opted for are simple, reliable and familiar. The mast has been changed and her chord increased to the maximum allowed under the rules (800 mm). Her dagger board now has a trimmer (multi-directional trailing edge) to improve her upwind course holding capacities. Shrouds (cables which hold the mast laterally) have been moved aft to allow for a bigger gennaker (downwind sail), the boom has been changed, thereby saving 60 kg and the transmissions have been  modified for more sensitive helming. Last but not least, she now has a lifting central rudder (after what happened in the Québec-Saint Malo race) for offshore races. We know that Groupama 2 will be tough to beat in Grand Prix but Gitana 11 performs well in blue water races. This year’s programme has two high-point ocean races – Lorient-Hyères (start on 8th May) and the Transat Jacques Vabre from Le Havre to Salvador de Bahia (start on 6th November). 
    One or two changes have occurred in the crew line-up. Yann Eliès was unable to take par tin all of the events as he is racing in the Solitaire du Figaro this summer. Antoine Mermod, who was engineer and developer for Sergio Tacchini last year will be replacing him in the pit. Nicolas Berthoud bows out to Jean-Baptiste Le Vaillant, master sailmaker with the Incidences loft in La Rochelle, a major trump card for the Gitana Team as he is widely recognised as being the crew on the multihull circuit. He will be overseeing the making of new sets of sails for both trimarans. Loïc Le Mignon, who already won the Transat Jacques Vabre with Loïck Peyon, becomes Gitana 11’s boat captain. Finally, Jean-Yves Bernot is joining us as weather wizard and navigator on the first race, from Lorient to Hyères. One of the most highly-experienced maritime meteorologists in the world. 

    Winter training sessions

    In between seasons, from the end of November to mid-March, it was important for team cohesion that the helmsmen and tacticians continued to sail. Throughout the winter, every fortnight in La Trinité/Mer, the guys spent their weekends racing on Open 7.50s, a small, fast and highly technical 7.50 m one design monohull which behaves in a very similar way to multihulls. The level of racing is very high indeed and many of the fellow ORMA yachtsmen take part (Alain Gautier, Armel Le Cléac’h, Michel Desjoyeaux, Charles Caudrelier…). We have two boats entered with Thierry and Fred at the helm with the clear aim being to put on a brilliant performance in the Spi Ouest France, the event which marks the close of the winter training sessions, where 500 boats enter into battle from 25th to 28th March. This year 24 Open 7.50’s will be taking part. »
