  • 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.

    Yann Guichard and his three crew conclude the Trapani event in fourth place tonight despite a brilliant start to the Grand Prix. For the competitive crew of Edmond de Rothschild Group, this finish at the foot of the podium is bound to be a disappointment. However, already they are setting their sights towards Andalusia and the town of Almeria, where the winner of the Extreme Sailing Series 2010 will be decided in a fortnight’s time.
    The fourth meet of the season, despite being contested in a Mediterranean destination famed for its mild climate, has been marked by some breezy conditions and what might easily be described as some lively races:“In this Grand Prix of Trapani, conditions have been windy and, with the exception of Thursday, we’ve always had more than 15 knots. For the time being, with one regatta to go till the end, we’ve had a championship dominated by the breeze. As such our decision at the start of the year to make the crew a little heavier and stronger for this type of weather was the right one”said Yann Guichard assuredly.
     
    Prior to this final day of racing in Sicily, the catamaran fitted out by Baron Benjamin de Rothschild was in third place on the provisional podium. For Yann Guichard and his men, the objective was clear: to sail cleanly and try to hunt down the second place and naturally keep their distance from any pursuers. Up until the third race of the day, things were going really smoothly and the sailors from the Gitana Team were gradually making up ground on Masirah. Unfortunately, the end of the afternoon didn’t shine favourably on them: “We sailed well during the first three races, systematically coming in the top three. After that though, Muscat prevented us from sailing as we wanted to in view of the overall championship ranking. That then enabled the other Omani boat and Ecover to get down to business without us and score 2nd and 3rd in the event. It’s a calculated move that we could’ve pulled in Kiel, as we certainly had the chance to do that, but we didn’t want to. It’s a mindset which isn’t reminiscent of mine or that of my crew!” admitted the Gitana skipper with a hint of bitterness, before saluting the exemplary job done by Pierre Pennec, Hervé Cunningham and Yves Detrey during the past four days of competition: “My crew have once again performed very well and our fourth place in Sicily isn’t representative of the quality of their work. We’re coming to the end of the championship and with the final outcome drawing near, our adversaries are beginning to weigh up the scores and are basing their sailing on that, that’s all.”
     
    In the overall ranking of the Extreme Sailing Series 2010, the Grand Prix of Trapani hasn’t been a great operation for the crew of Edmond de Rothschild group, who have conceded their first place, as Yann explains: “This evening we’ve dropped a step on the 2010 championship podium and, as we forecast pretty early on in the season, everything will be decided in Almeria. We mustn’t question ourselves at all when we’re there. We simply have to ensure we’re in front and give everyone a run for their money.”
     
    A little over a month from the start of the Route du Rhum, Yann Guichard is constantly linking together the Extreme 40 competitions and his preparation aboard the maxi-trimaran fitted out by Baron Benjamin de Rothschild. In this way, the Breton skipper will be back in Paris, France tomorrow, where he will attend a press conference on Tuesday evening for the famous transatlantic race between Saint Malo and Pointe-à-Pitre. Then, on Thursday morning, he’ll be back with his shore crew in La Trinité-sur-Mer to continue his training on Gitana 11. A busy programme ahead then, though Yann Guichard seems very suited to the rhythm.
