  • 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.

    Thanks to the arrival of a northerly air flow, the Extreme Sailing Series fleet benefited from prime sailing conditions and livelier racing for the second day of competition in the Trapani Grand Prix. Struggling to get above seven knots yesterday, the anemometers indicated a fine breeze of around ten knots, gradually building throughout the course of the afternoon to round off the day at around 15 knots. As such the ten crews were able to show what their catamarans were made of and sail at full speed flying a hull. Pierre Pennec and his men proved to be particularly adept at this particular game since they put up the second best performance of the day and have moved up to fourth place in the provisional standing.

    Despite a slight chop late afternoon, conditions were just as summery as yesterday in Trapani with glorious sunshine and soaring temperatures. However, the most important factor remains the arrival of a steadier breeze, which enabled the race committee to run six fine races at the foot of Erice Mountain. Indeed the forecasts from Gitana Team’s meteorologist, Sylvain Mondon, who this morning announced a northerly wind comprising between 12 and 16 knots, were borne out on the water. Furthermore Edmond de Rothschild Group’s crew were able to make very good use of it: “With this wind strength, we are among the fastest boats of the fleet and this enables us to hold our own more easily in difficult situations and make a difference against our adversaries. It’s often said that speed makes you intelligent and this proved true once again” explained Pierre Pennec on his return to the dock.

    However, the wind isn’t everything and the men from Gitana Team clearly had what it took to raise their game, as was demonstrated by their first victory of this Grand Prix on the final race of the day: “We knew how to sail with a good margin for safety to avoid collisions and above all penalties, which often result from such racing and are detrimental to finishing a day with good results. I think that several race victories were within our grasp today as we got in some good starts on the whole. However, through our desire to sail without taking big risks we let a few first places slip by us. Nevertheless, it’s a positive outcome today as we were consistent. This has enabled us to get back in contact with the top spots and rack up some precious points ahead of our rivals” admitted a satisfied skipper.

    After today’s six races, the catamaran fitted out by Baron Benjamin de Rothschild has moved up two places in the provisional standing, switching sixth place for fourth place, which is the second best performance of the day. Line honours went to Max Sirena’s Italian team who moved up to second place from fifth. Edmond de Rothschild Group’s closest pursuer is eleven points astern of them this evening, which isn’t a lot but does leave the team in a more comfortable position than yesterday.

    Tomorrow, Pierre Pennec and his crew are set to confirm the upward trend in their performance this Thursday but it will be in quite another setting. Indeed, the Extreme Sailing Series fleet is switching race zone to get even closer to the Sicilian public. The next three days of races will be run in the nautical arena formed by the port of Trapani. As a result the format of the races will be different, with shorter courses and another way of approaching the strategy, as the skipper of Edmond de Rothschild Group explains: “In the arena races, the distances are shorter and as such everything happens a lot quicker. The decision making, whether it’s in the course mark approaches or the trajectories, must be very fast and pertinent. Christophe (Espagnon) is also less involved in the tactics and more geared towards the manœuvres.” For Hervé Cunningham, the bowman, the change of format will call for a bit more aggressiveness in the start phases: “In the races run over the past two days, the start is a very important phase but the playing field here also enables us to attempt to pull a few special moves, favouring a particular side of the race zone. As such a start midway up the table can’t necessarily be ruled out. In the ‘stadium’ races, the courses are a lot shorter and the competition is less open. The starts become essential if you want to rank among the frontrunners when crossing the finish line. You have to be more of an opportunist and in on the action from the outset.”

    The first warning signal for the third day of competition is scheduled for 1500 hours.
