  • 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.

    A month to go till the launch of Edmond de Rothschild Group.

    Last week, Tuesday morning to be precise, the MOD Edmond de Rothschild Group left the sheds at Keroman Technologies and took to the water to cover the few metres separating her from the Océan Développement site, also located in Lorient, over towards the Keroman submarine base. Although this wasnt quite the launch of the new Gitana craft, this change of workshop remains fairly symbolic because this is when the one-design No.4 hit the water for the very first time. It also means that the end of the fit-out is fast approaching. The order placed by Baron Benjamin de Rothschild in March 2010 will thus be completed on Tuesday 25 October 2011, the scheduled date for the launch of the 70 footer Edmond de Rothschild Group.

    In March 2010, Baron Benjamin de Rothschild expressed a desire for Gitana Team to be one of the protagonists on the new Multi One Design circuit by taking command of the one-design No.4. However, the construction of the new Gitana craft itself began a year later in the three nerve centres where this latest generation trimaran is created. Like a jigsaw puzzle, the different pieces are manufactured separately before being assembled in Lorient. In fact, the project management of the MOD 70s is entrusted to the company CDK Technologies, based in Port-la-Forêt, but the main focus of the Finistère-based company is the manufacture of the central hull. Meantime, a few kilometres further south, in Vannes, the Multiplast yards are getting down to the construction of pairs of floats for the 70’ one-designs. As for the beams, these are made not far from the banks of Lake Geneva. Indeed the Décision SA yard, which has played an active role in the development of the D35 one-design class, is part of the adventure. Once these main structural pieces of the platform are manufactured, they are delivered to the sheds of Keroman Technologies in Lorient to be assembled. The work on the MOD 70 Edmond de Rothschild Group began in mid-July and was complete by the start of September. After a few weeks spent on her livery, the trimaran Gitana has now joined the Océan Développement yard, opposite the Cité de la Voile Eric Tabarly in Lorient, where she’s on the home straight in her construction programme.

    Over the coming weeks, the MOD SA teams will proceed with the positioning of the deck hardware (winches, blocks, sheaves…), the installation of the electric and electronic circuit, the hydraulics and the mechanics aboard the boat, not to mention the essential attaching and tensioning of the trampolines which link the hulls together. Finally, the trimaran will be equipped with all her different appendages (float rudders, daggerboards and foils). In short, another five weeks’ work in prospect before the MOD 70 Edmond de Rothschild Group can be placed in the capable hands of the men from Gitana Team. A month’s sea trials will follow to commission the one-design.

    Gitana 11, guest at the Krys Match

    From 6 to 8 October 2011, the first confrontation of the Multi One Design will take place in La Trinité-sur-Mer, south-west Brittany. It will certainly be a friendly encounter as the score won’t count towards the Multi One Championship, but the class’ first three trimarans and their crews will be able to size each other up during the three days of racing, where there will be alternate Races and shorter Speed runs. As they await the arrival of the MOD No.4, the Gitana Team will nevertheless be part of the action aboard one of the flagships of Baron Benjamin de Rothschild’s fleet, Gitana 11. Spanning 77 feet, compared with the 70 that make up the MODs, Gitana 11 is very similar to the one-designs. Indeed, even though he’ll have to be patient for just a little longer before he finds himself on an equal footing with his rivals, skipper Sébastien Josse is delighted at the prospect of this meeting: “The Krys Matches are an opportunity for us to do battle with some of our future rivals. It’s always more appealing to see how you perform against the others rather than sailing on your own. On paper, Gitana 11 is slightly faster, but we saw during the Rolex Fastnet Race that the boats were fairly similar in terms of performance. In contrast to the Fastnet, the Krys Matches are round-the-cans races. Such an exercise is synonymous with numerous manœuvres, which the MODs are more suited to than Gitana 11. In fact, it shouldn’t be forgotten that the boat was modified for the Route du Rhum and for single-handed sailing. However, it will all depend on the weather conditions. The idea is to get some races under our belts and see how the crew behaves during the races manœuvres, with less focus on the speed tests!”

    For this Breton meeting, the skipper of the future MOD Edmond de Rothschild Group has put together a crew of experienced sailors. He’ll be accompanied by Thomas Rouxel, David Boileau, Olivier Douillard, Antoine Koch, Florent Chastel, Jean-Baptiste Levaillant and Christophe Espagnon.
