  • 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.

    Thierry Duprey du Vorsent and Erwan Le Roux arrived in Salvador de Bahia in the small hours of Thursday morning French time, in the heat of a Brazilian night! The trade winds played a rotten trick on them slowing them down right to the bitter end, but the two skippers were overjoyed finally to touch down after seventeen days slip-sliding along and more than their fair share of problems. Gitana X closes the door for the 60 foot multihull line-up of the 7th run of the Transat Jacques Vabre. Frédéric Le Peutrec and Yann Guichard were both there to welcome their friends back to dry land and share in pleasure of having both Gitana docked in Bahia.

    Shortly after 2 o’clock on Thursday 24th November, (02 hours 6 minutes and 33 seconds French time to be exact), Thierry Duprey du Vorsent and Erwan Le Roux sailed their steed into Bahia for a race time of 17 days 11 hours 06 minutes and 33 seconds, thus three days, nine hours, twenty minutes and four seconds after the winner. Ups and downs of daily life on board for the duo on Gitana X. Satisfied on the one hand to have completed the course of the Transat Jacques Vabre fourth in the ORMA trimaran fleet, but disappointed on the other hand not to have run the race in alongside the rest of the fleet as they twice had to stop due to technical problems. Along with the joys of gliding downwind in trade winds of more than 20 knots, the difficulty of avoiding being stuck going nowhere fast when the wind dropped altogether for hours on end. But Thierry Duprey du Vorsent and Erwan Le Roux recall more easily the best moments in the 5 190 mile passage covered at an average speed of more than twelve knots. This fourth place in the Transat Jacques Vabre also enables them to take fifth place in the ORMA Multihull Championship 2005.

    Thierry Duprey du Vorsent:

    « It was actually tougher mentally than out on the water! We were shaken off when there were still 400 miles to go. No-one in front, no-one behind – and these boats are not made for cruising. When we made our second pitstop in Lanzarote we really asked ourselves the question of whether it was worth continuing or not. Groupama-2 had capsized just beforehand – it makes you think twice!
    We end up finishing very late of course but we really did clock up a whole host of problems. Nothing to do with the boat’s level of preparation which was spot on. Everything that happened was unforeseeable. In fact we’re really proud of the whole team, always there when we needed them, ready and willing – and efficient with it. It’s rare to have a team support you to such an extent when you are really down in the dumps. Bravo and thank you once again to the Gitana Team.
    Bahia is a great place to finish – music, noise, the people. We haven’t seen any of that for days! Pure magic. And as we haven’t got a radio on board, we haven’t heard a sound for ten days. It’s brilliant!  » 

    Erwan Le Roux:

    « Finishing the course in stormy squalls, wind, no wind, and wind again… Fifteen knots then nothing and then gusting. Trying mentally! But in the end, we were lucky compared to those who had to retire. We asked ourselves all sorts of questions after our rudder broke and then mainsail tearing. But it’s great to get into Bahia even if it is after everybody else. You have to look ahead. We’ll be back in 2007. Also, when you look back over the course we sailed, coming out of the front two days after the start from Le Havre, we weren’t that badly placed at all. We were in a good position, under the fleet, nicely placed to join the front runners without forcing. But of course we lost a lot of time with the torn mainsail, not to mention the loss of distance and heading. After that it was just one thing after another. And yet here we are and everything’s fine! It’s great to have seen this race through to the end, to have sailed the boat to the finish and in good condition in spite of it all. Gitana X suffered so did we. But we’re over the moon to be here. »
