  • 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 second spot on the Transat Jacques Vabre podium.

    In crossing the finish line opposite the lighthouse of Salvador de Bahia port on Wednesday at 10:51:06pm (French time) Lionel Lemonchois and Yann Guichard concluded a rapid transat done and dusted in 10 days 9 hours 49 minutes, shattering the record for the event set in 2003 by over 36 hours. The final day was frenetic, followed by a more gentle finish, the blue trimaran owned by Baron Benjamin de Rothschild having achieved an average speed of 27.4 knots over the last 24 hours’ racing and covering over 658.5 miles: another record to go down in the annals of Gitana history.

    Despite a broken foil around Madeira which fatally compromised their chances of victory in this edition, the Gitana Team crew gave their all throughout this race and were rewarded for their excellent endeavours with a fine second place.

    Review of a race characterised by attack and commitment

    Start amid light air

    Having set off from Le Havre on 4 November in light air, conditions not best suited to Gitana 11, Lionel Lemonchois and Yann Guichard – in agreement with their meteorologist Sylvain Mondon – immediately opted to take a very northerly course for the exit from the Channel, thereby deliberately choosing to enter an anticyclonic bubble and letting the lighter boats outstrip them. But their strategy proved to be effective when the wind returned as promised, allowing Gitana 11 to move to the head of the fleet come Monday evening.

    However, at dawn on Tuesday in the ocean off Cape Finisterre, a loud cracking sound was followed by another, leading to an inescapable conclusion: Gitana 11 had just lost her starboard foil. Instead of giving way to negativity, the crew kept on racing and continued to advance at a rate in excess of 25 knots a day, before choosing the best spot to make a pit stop for repairs. In order to optimise their relaunch, the Canaries were finally chosen instead of Madeira, and the Gitana Team on standby in Gran Canaria did some sterling work to complete the operation in little over two hours. Soon back in the thick of it, the Gitana 11 crew were then pegged back by a windless zone caused by thick cloud on leaving the Canaries, forcing the dynamic duo to adopt an all-out attacking approach heading towards the doldrums.

    Doldrums: the acid test

    This area formed by exceedingly complex and unpredictable weather systems characterised by storms, highly violent squalls and windless zones turned out to be especially active and extensive on this transat. At a stage of the race where fatigue had already begun to take its toll, the sailors faced a challenge where clarity would be at a premium. And it was there that the Route du Rhum winner and his co-skipper Yann Guichard mustered all their mariner’s talent, human determination, and competitive edge. Applying a brilliant offensive strategy and deploying every ounce of their energy in manoeuvring, the two navigators pulled off a masterstroke by making an “easterly” crossing along two main lines. First, they found a passage at the tip of the infamous Atlantic windless triangle, then negotiated the squally area by surfing the ridges in optimum style. Thanks to this strategy, the trimaran managed to emerge from this sensitive area in record time and most importantly to find herself at a perfect angle to attack the trade winds of the Southern Hemisphere, finishing the last section of the race on a reaching leg, the ideal pace for Gitana 11. Lionel Lemonchois, supported by Yann Guichard, did what only he can do: to dare to travel at unbelievable speeds. The gap between 11 and the winner Groupama 2 was thus whittled away hour on hour, but alas not enough to snatch final victory. Pascal Bidégorry, meanwhile, saw his chances of securing second place gradually disappear over the horizon.

    Before the start of the race, Yann Guichard said of Lionel Lemonchois : “what I like best about him is that he never ever gives up.” So the performance of Gitana 11 can today be hailed, as it is also the performance of two exceptional sailors whose tenacity was total, even in moments of misfortune. Moreover, it is the performance of a united team, all fully focused on the success of the boat, not to mention the sound, prudent and committed advice of “the third man”, Sylvain Mondon from Météo France, the vital “grenouille” to whom the two sailors owe so much. 

    Benjamin and Ariane de Rothschild, along with all the staff of the LCF Rothschild Group, salute the two sailors for allowing them to experience this superb race packed with panache, intensity and twists and turns aplenty.

    Loïck Peyron, the Gitana Team director who is still at the helm of Gitana Eighty, took time out to heap praise on the Gitana 11 crew recently arrived at Salvador: “Lionel and Yann surmounted their technical difficulties and sailed a superb race. It wasn’t quite enough but they still made a magnificent showing. A job well done!”

    Lionel Lemonchois : “It was by no means an easy race, more of a good scrap. As usual I’d like to say thanks to Benjamin! Teaming up with Yann was just great. I got to know this superb sailor a lot better. He’s a larger than life figure, always there when it matters and like me he never stops talking! ” Yann Guichard also congratulated the great team working alongside Lionel Lemonchois. Racing at speeds of 37.6 knots, the duo took Gitana 11 into unknown territory to claim a superb second place. Both sailors also expressed their gratitude to Sylvain Mondon for his unstinting support and hard graft.
