  • 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 11 takes 3rd !.

    Just 20 seconds separated Gitana 11 and Foncia at the finish. In the very last miles of the race, Frédéric Le Peutrec burst onto the scene pipping Armel Le Cléac'h at the post and taking 3rd place into the bargain.

    Just 20 seconds separated Gitana 11 and Foncia at the finish. In the very last miles of the race, Frédéric Le Peutrec burst onto the scene pipping Armel Le Cléac’h at the post and taking 3rd place into the bargain. Pascal Bidégorry and Michel Desjoyeaux took 1st and 2nd respectively. Gitana X’s crew sailed her to 5th place after a closely fought race where the crew exploited the boat’s capacities and the slightest opportunity which came her way !

    A lots happened between Cape Corsica and Nice. Situations completely turned on their head, accelerations, pitstops mid-flight, surges of adrenalin and sessions down in the dumps. Here’s an overview of what went on over the past couple of days.

    – On Saturday Franck Cammas had to throw in the towel after discovering a crack in the crossbeam off Malta. This left the leadership place open for Pascal Bidégorry, who had a hundred mile advantage over Michel Desjoyeaux and  Frédéric Le Peutrec, neck and neck at the time.

    – By Sunday Banque Populaire had lost ground and had a mere 50 mile lead over Géant who had decided to stick close to Sicily. Gitana 11 opted to head for Tunisia but at the same distance from the finish, Frédéric Le Peutrec had gone of in search of new wind which was supposed to come in from the west. First to latch onto this wind, he had actually moved into second position by the evening.

    – Monday morning and Gitana was just 8 miles from the leader and had put a comfortable 70 miles between her stern and the three boats tailing her ! By Monday evening, leader Pascal Bidégorry was still within reach (20 miles) and the gap with rest of the fleet had slipped to 100 miles !

    But everything changed overnight. The SE breeze kicked in abeam as a new puff of wind took Banque Populaire across the finishing line on Tuesday morning (7h 36′ 17”). When Frédéric Le Peutrec passed Cape Corsica, he got caught in a wind hole marking the transition between the old wind which had been a true driving force for  Pascal Bidégorry, and the new wind which propelled Michel Desjoyeaux, Armel Le Cléac’h and Thierry Duprey du Vorsent forwards. Four trimarans which found themselves together after a race distance of almost 2 500 miles. When they saw Gitana 11 up ahead – going nowhere fast – all they had to do was to sail round the calm zone and overtake her, just sixty miles from the finish. Géant leapt ahead crossing the line six and a half hours after Banque Populaire, winner of the first edition of the IB Group Challenge. But the battle for third between Gitana 11 and Foncia was not over, in spite of the one mile lead held by Armel Le Cléac’h. A spot of wind kicked in and speeds of up to 25 knots were attained with flying gennakers. Both boats entered Nice’s Baie des Anges side by side ! Frédéric Le Peutrec gradually made up the distance lacking, passing leeward of Foncia beating her to 3rd by 20 seconds – an amazing finish after a race nine days long ! A differential of 0.0028 %…

    The crew is washed out by this eventful final and a little disappointed too but Frédéric Le Peutrec knows how to overcome it all.

    « A mixture of frustration and satisfaction. Satisfaction as we managed to make it to third by the skin of our teeth, fighting like mad dogs in a 25-30 knot wind to snatch back the mile Foncia had taken ! Flat out with the gennaker up. Not the sort of sailing we can do in Grand Prix contexts. We let out hair down after 8 days at sea. An exceptional finish spurred on by a surge of adrenalin. 
    Cape Corsica was dreadful for us. On the approach we could see that the wind was going to change from the south and that those behind were starting to close in. As we were slightly offset compared to Banque Populaire, she managed to break away at Cape Corsica. A wind hole separated us from her, typical Mediterranean conditions. We were stuck there for a while until the wind came back astern, bringing three boats with it ! They managed to sail round us which is how Géant made it across the line one hour ahead.

    But this was a superb race. Lots of chopping and changing. Nerve-wrecking racing and tiring physically. Ever since the start, this felt like a Grand Prix. From start to finish, from the prologue of Groix to the Finish in Nice ! At times there was some unbelievably close one-to-one racing, particularly with Géant. We were within sight of each other for half a day with lots of canvas up and the crew hiked out. Exciting stuff to watch but unbearable experience. Eventful but frustrating never the less as in the windless zone there was nothing to be done except sit by and watch the race happen around us. I went through a similar situation in the Québec-Saint Malo 2000 with Marc Guillemot. What had been a 600 miles lead just whittled away into nothing !  Each boat found herself in the lead or offset behind at one moment or other. A real accordion on two occasions – once when we were in the lead at Gibraltar, and a second time slightly behind in the Gulf of Tunis, once again in the front seat close to Sardinia and shaken off after Corsica !
    We are pleased with the solo option west after the strait of Sicily where we came within reach of the lead. The Mediterranean has really lived up to its reputation !

    The crew is well and truly out of it. It’s quite a boxing match. Eight days at sea to finish in dead calm only to cross the line in a 30 knot breeze with the gennaker up ! Altogether unreasonable. The boat is in perfect condition – excellent preparation, a reliable boat, no gear failure or damage. The lifting rudder came up at the right moment when we struck something. Brilliant !
    All in all we’re really chuffed as fourth would’ve been terrible. Third is not bad at all »
