  • 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.

    War of nerves in Boston.

    Decidedly ruthless, the Boston race zone today decided to play on the nerves of the eleven competing crews. Extremely shifty in the first races, the wind conditions did improve over the course of the afternoon, enabling the sailors to contest some more consistent races. In the top three five times in a row out of a total of seven races run this Friday in Boston: the men of Edmond de Rothschild Group regained the consistency which was lacking in their performance yesterday. Though they’re still in fourth place in the provisional ranking, Pierre Pennec and his three crew have closed on the top trio and proven, if there were a need, that they’re very much in contention for victory in the American event of the 2011 circuit.

    Incisive and thus consistent in their results, the men from Gitana Team made it back to the quays of Fan Pier with more of a spring in their step than the previous day: “It’s been a good day. We’ve made progress with the way things worked on the boat, especially in terms of communication, as well as in the analysis of the race zone. This progress could be felt in the start phases, which were better today and we managed to make up points on our direct adversaries, with the exception of Emirates Team New Zealand, who enjoyed the best day of the fleet. This evening, we’re in the same position as yesterday in the provisional ranking, but in terms of the points which separate us from the podium, we’re already doing better” admitted Pierre Pennec.
    Fourth after the seven races contested this Friday, Edmond de Rothschild Group is now just five points shy of its closest rival, whilst it is thirteen points ahead of its pursuers on Luna Rossa, compared with just two yesterday. For its part, Terry Hutchinson’s crew is holding onto the lead in the Boston Grand Prix, but with three days left to go, they can feel their adversaries breathing down their necks.

    Edmond de Rothschild Group’s crew finished this second day of the competition with a slightly over-zealous indiscretion: lying in second behind Team Extreme during the final race of the day, Pierre Pennec and his men glimpsed the possibility of a victory down the home straight. They risked all but copped a penalty for hitting one of the marks that defines the finish line. This disappointment cost them precious points, but it just goes to show how much the four sailors want to win: “The slightly timid way we operated yesterday was replaced with a more aggressive attitude. We got off to some good starts today, which had a favourable effect on the rest of the race. We committed errors in the first and last race of the day, but all in all it was a positive day as these failings are easy to correct. We’ve got our bearings and we’re ready to do battle!” said a smiling Christophe Espagnon.

    The long weekend, which will conclude on Monday with the American national holiday, begins this evening. As such big crowds are expected on the quays of Fan Pier over the next three days to admire the Extreme Sailing Series fleet in action. Sticking to its familiar routine, the race committee will launch the first race of the third day of competition shortly after 1400 hours (local time).

    The team speaks out

    Christophe Espagnon, mainsail trimmer: “The first two races were run in the forecast wind conditions, namely light and very shifty airs which, like yesterday, led to great upset in the rankings during the races. It was a bit of a lottery. Fortunately though, a thermal breeze kicked in over the course of the afternoon, which enabled us to sail in slightly more wind. In the zone where we were racing, there aren’t really any offshore zones as we’re surrounded by buildings or sea walls. However, the wind was a lot more open coming from the sea. The mistakes we made today were due to a lack of concentration or rather too much focus on what our adversaries were doing and on getting the boat making headway. During the first race, we kind of forgot a bit about the playing field set by the race committee. Such an error earns an immediate penalty, which ultimately led us to finish outside the time in the first race.”

    Thierry Fouchier, headsail trimmer: “As soon as there’s more wind, as proved to be the case during the second part of the afternoon, we’re more at ease and our good speed enables us to get away from the bulk of the fleet more easily. However, the race zone still remains hard to read as the winds change a great deal in terms of direction and intensity. In such conditions, it is really important to stay calm aboard the boat and to very quickly move onto the next race if the desired result isn’t achieved on the previous race. That’s what we did on Edmond de Rothschild Group as, despite finishing outside the time on the first race, we quickly refocused and racked up five races in the top 3.”
