  • 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.

    The summer break marking the end of the first part of the Cafe Ambassador Multi Cup offers the opportunity to carry out an initial sporting evaluation after the completion of 19 Grand Prix rounds and one ocean race, the London – Alpes Maritimes.

    The dismasting of Gitana 12 on the eve of the Trophée du Conseil Général des Alpes Maritimes totally disrupted the programme of Thierry Duprey du Vorsent and his crew. They were only able to train for one day before the Grand Prix de Marseille and the almost windless conditions experienced in Portugal show that the white trimaran is not really comfortable at close quarters in terms of course holding and acceleration in less than five knots of wind. While the crew are yet to fully discover the boat’s subtleties, it is nonetheless undeniable that Gitana 12 can compete more effectively with the fleet in a more vigorous breeze. The Grand Prix du Port de Fécamp, contested in September and usually quite windy, should confirm these first impressions. It is worth remembering that the ex-Bonduelle was completely overhauled this winter and that her relaunch only took place two weeks before the London-Nice race.

    For Gitana 11 too, the change of central hull amounted to a massive job and the crew had to recover their reflexes gradually. The Grand Prix de Trapani, extremely windy at over twenty knots and with a very rough sea, still brought victory in one round for the crew. During the Marseilles meeting, the breeze was decidedly less sustained and on flat seas, Gitana 11 had a superb coastal course, staying hot on the heels of Géant right to the finish and overtaking Groupama 2 under gennaker. It didn’t take Loick Peyron long to re-familiarise himself with the trimaran, and Portugal saw 11 clinch five second-place finishes behind Franck Cammas’ untouchable machine in the six rounds contested. In what were tricky sailing conditions marked by erratic winds, the crew of Gitana 11 frequently managed to come back strongly from difficult situations courtesy of a few tactical masterstrokes and some superb manoeuvring. In this respect also, the Grand Prix du Port de Fécamp will offer a chance to confirm the boat’s potential in the breeze.

    As regards the rankings for the Cafe Ambassador Multi Cup Championship, the pecking order has been firmly established even before the first round of the last Grand Prix in Normandy (8-10 September), but the Gitana Team will be intent on realising its potential and challenging the supremacy of the last born of the Orma trimarans.

    For the Grand Prix de Marseille, Gitana also announced the redeployment of Loick Peyron, the team’s sporting director, to the helm of Gitana 11, with Frédéric Le Peutrec becoming onboard tactician. However, by mutual agreement with the team’s management, Frédéric Le Peutrec opted to leave the Gitana fold after two years in control of Gitana 11 in order to be able to devote himself fully to his search for a new project. Every member of the Gitana Team wishes him a great deal of success in his future initiatives.

    Frédéric Le Peutrec: “It wasn’t an easy decision to take but I felt I had no choice after the Grand Prix de Marseille. This last two years with the Gitana Team have been extremely beneficial. I’ve learned a great deal and I’d like to thank Benjamin de Rothschild for offering me the chance to have this great experience. But at the start of the 2006 season, the decision was taken to remove me from the helm of Gitana 11 and although I was offered the opportunity to stay with the team as tactician, I soon realised that would not bring me fulfilment. For this reason, we mutually decided that I would leave the Gitana Team. The early season results were not up to scratch in 2006 and, harsh though it may be, I understand that the team’s objectives are paramount. I’m disappointed to be going, but this experience will stand me in good stead as I try to move forward and get my teeth into a new project, something which I just couldn’t see happening if I stayed with Gitana 11. Yann Guichard, whom I sailed with a lot in Tornado and deeply respect as a person and a friend, has joined the team at Portimao. He’s going to take charge of onboard tactics, which has got to be a good thing. He knows Gitana 11 well, as we finished second together in the Transat Jacques Vabre 2005… I think that’s the best option, and I hope to be back out on the water competing with the new team of 11 before too long.”
