  • 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.

    You have to have nerves of steel in the Extreme Sailing Series… The day that has just come to an end in Istanbul – the fourth of the Grand Prix – once again demonstrates that on this circuit nothing is set in stone, and anything can happen, good and bad. This is all the truer this year with a fleet where everyone is of such a similar standard. Leader in the provisional ranking yesterday, the crew of Edmond de Rothschild Group has yielded its place to the New Zealand sailors from Emirates Team New Zealand and finds itself down in fourth position tonight, eleven points shy of Dean Barker’s men. However, there’s still everything to play for giving the proximity of the top 5. Victory is still within grasp for the sailors in Gitana Team.

    The deterioration of weather conditions that started yesterday has continued this Saturday in Istanbul, with low cloud and rain showers marking this fourth day of the competition. Along with the missing sunshine on this Turkish race zone today, the wind proved rather more timid today, and above all more capricious than during the three previous days. Indeed it oscillated between 6 and 9 knots throughout the afternoon. Unfortunately the performance by the crew on Edmond de Rothschild Group was reminiscent of the weather: “It’s a gloomy day for us, just like the weather!” said Thierry Fouchier ironically.

    Displaying impressive control and a particularly consistent performance yesterday, the men of Edmond de Rothschild Group didn’t manage to demonstrate the same prowess this Saturday. Penalised on several occasions by the on-the-water judges, the crew is paying for its mistakes this evening: “We racked up three penalties out of the eight fleet races contested and that’s three penalties too many if we’re to stand a chance of ranking well… A 360° (a manœuvre that has to be performed to make up for the penalty) doesn’t help matters, especially within such an homogenous fleet and on such short courses. However, these penalties were fully justified as we made mistakes today. We’ll have to try to erase all thoughts of that very quickly tomorrow and sail cleanly like we’re used to doing”, admitted Hervé Cunningham, the bowman. Despite this, the catamaran fitted out by Baron Benjamin de Rothschild remains very much in contention for victory in the Istanbul Grand Prix and Pierre Pennec’s men have every intention of defending their chances right the way to the finish. Indeed, this evening, the separation is so slight between the top five boats, that it’s impossible to say which of these five will win Act 3 of the Extreme Sailing Series. As such, once again, everything will be decided over the course of the final day of the competition and maybe even the last race of this Turkish Grand Prix, the notorious race which scores double points: “We’re very close in terms of points. The pressure will increase tomorrow so it won’t be a surprise to see the leading boats committing errors and overshooting the start line… that’s where we’ll have to put up a solid performance. We’re ready for it and keen to get out on the water”, adds Pierre Pennec.

    Tomorrow the racing programme is set to change and the afternoon will be run in two stages. The first round will begin at 1500 hours local time (1300 GMT) and will come to an end an hour and a half later. At 1800 hours, the ten one-designs still competing will head back out onto the Golden Horn race zone for two more hours of racing. The outcome of the Istanbul Grand Prix will be revealed shortly after 2000 hours local time.

    Team Extreme, not participating but ranked
    Yesterday, during the fourth race of the day, Team Extreme was the victim of some serious damage following an impressive collision with Alinghi. The one-design skippered by Roland Gaebler was very badly damaged in the impact and the boat’s structure itself was affected. Repairs in Istanbul quickly proved to be impossible for the crew. With the responsibility for the incident being down to the Swiss team, Team Extreme is the “infringed yacht” according to the terms used in nautical jargon. In such an event, even if the yacht carrying a European flag is no longer racing, it amasses points and will be ranked at the end of the event. For this the jury takes the average from the races sailed by Team Extreme during the first two days of racing.
