  • 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.

    Light air.

    At the Portugal Grand Prix in Portimao on Saturday, we were treated to a race within a race, as Loick Peyron on Gitana 11 and Michel Desjoyeaux aboard Géant gave a demonstration of “the art of sailing” during their game of cat and mouse in the light air of Portimao bay. And it was Gitana 11 who came up trumps by confirming her second place in the provisional rankings by taking a three-point lead over her closest rival at the end of this second day.

    Onboard Gitana 12, expectations were also largely fulfilled! The contest between Géant and Gitana 11 forced her to manoeuvre much more, which allowed 12 to make up for starts still lacking in aggression by getting much closer to her opponents on the day’s two rounds. These races contested at such close quarters will surely have served as a considerable tonic for the troops!

    Loick Peyron, skipper of Gitana 11…

    “It was a nice little derby, especially as 12 was not far behind on the second round. Because we couldn’t afford to lose any time if we wanted to keep fighting for supremacy with Géant, we ended up forgetting Gitana 12, which gave them the chance to come back! Our overall tactics were to try to get her to squeeze in behind us, not just because she’s a fellow Gitana, but primarily because it would mean we’d pinch an extra point off Géant! But at least we’re a few points ahead of her anyway! And then of course, what’s most important about sailing is having a proper race, even in such an evanescent breeze, and that was certainly the case today. Everyone on the water was in the mood for a race… which is what causes the problems and makes it interesting at the same time!”
    In conditions like these, the role of onboard tactician is essential…

    Yann Guichard, tactician on Gitana 11… explanation of text:

    “The aim of the game is not to follow the one in front and if you’re in front, it’s to control the one behind you so she doesn’t get away from you. Everyone knows Groupama’s faster, so it’s all about getting clear of her from the start so she doesn’t block us. Then, we try to stay with Géant while trying to block her because an extra point is important! In practical terms, when we’re in front of her, we’re controlling her. By that I mean that, up close, we try to mask her, either in the centre with wind abeam and downwind, the game is to stay between her and the marker so we always have priority when we arrive at the mark on the leeward side. But if you’re behind, you have to try to differentiate yourself from the boat in front, so at close quarters, you have to keep changing tack and gybing downwind, while always prioritising the finish at the marker buoy. We came out on top in this little game today, but it often hinges on the smallest of things!”

    Nicolas Raynaud, trimmer on Gitana 12…

    “It’s the first time we’ve sailed in wind conditions like these. In our first Grand Prix at Marseilles, there was plenty of breeze and now we find ourselves in 5 knots of wind… it takes a bit of time to get your bearings! But we’re making progress, and we really weren’t far behind today… Tactically, we pulled off some good tricks thanks to our performer, Benjamin de Rothschild, who was giving us the onboard lay lines. It was excellent! On the second round, we were only a length away from going past 2! On the first round, we messed up our start and then opted for the direct course, which was not such a good choice… Afterwards, we managed to come back by dint of perseverance and refining the trimming. We’re all still really up for it on board, and despite being far behind, we’re still in the game and can therefore make some more nice comebacks! We need to work harder on our starts, especially with such a high standard of competition on the water. These are not just local races!”
