  • 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.

    On the fourth day of the Italian meeting, which took place in light winds of between five and eight knots, the hierarchy established the day before has been upset once again. An Extreme 40 Grand Prix has never before seen so much indecision. With one day until the end of the competition in Trapani, the top six boats are separated by just fifteen points suffice to say this is a paltry amount given the races left to run. With a fighting spirit for the nine races contested this Saturday, Pierre Pennec and his crew were justly rewarded. Indeed theyve moved up onto the third step of the provisional podium behind the two Omani boats, with the team just nine points astern of the leader.

    Today the strength and direction of the weather conditions on the race zone enabled the race committee for the Extreme Sailing Series to bring the start as close as possible to the walls of the port of Trapani. As such the big Italian crowds on the race site had a front row seat to admire the spectacle. However, for the sailors, this new configuration made racing all the more difficult and a lot of the crews were called back for jumping the starts. On his return to shore, Pierre Pennec described this for us: “With the wind coming from a different direction today, the race committee gave us the chance to take some starts with the wind on the beam. This adds to the difficulty because with this angle, whatever the helmsman does (whether he luffs up or bears away) the boats move forward on the line. Given the really high level of the competitors, it was out of the question to let the others get the edge and set off in the second wave of competitors, otherwise you can’t expect to get better than sixth or seventh. As such you had to be attentive and pertinent as regards the timing, because if you set off too close to the line you end up with an individual recall for overshooting the start, while if you set off too far back you’re bound to end up being poorly placed in the ensuing race. This configuration was something new for me as a helmsman but the crew backed me up really well and the results are encouraging.”

    The cohesion between the four sailors is essential for getting good results. And this is only possible thanks to repeated discussions to analyse the errors committed after each race, as well as at the end of each day. In fact this is how Pierre Pennec and his men have always operated: “This afternoon, after the third race, we went over everything as a crew because there were things which cropped up again. Everyone expressed how it felt for them and their viewpoint and that enabled us to sort ourselves out and enjoy a better second part of the day”, admitted the skipper of Edmond de Rothschild Group. “The atmosphere aboard the boat was very calm, even at difficult moments, like in the second race where we got off to a very bad start and ended up in last position. However the crew remained united and positive. My crew know that I’m learning and they let me get on with it without pressuring me too much.”

    With a day to go until the end of the Grand Prix, it’s impossible to predict the outcome given how little separation there is between the top six boats. This evening, it’s Leigh McMillan’s men who have managed to take the lead in the provisional ranking. However, their stablemates – the second Omani one-design helmed by Ben Ainslie – are hot on their heels. The same is true of the catamaran fitted out by Baron Benjamin de Rothschild, which completes this trio, just nine points astern of The Wave Muscat. As such it’s an exciting scenario ahead and the nautical stadium will enjoy a very tense atmosphere in Trapani tomorrow: “We knew that the level on the water was going to rise from one event to the next and this is very clearly confirmed here. Proof of this lies in the fact that you need to take a lot more risks than in previous Grands Prix to score a place in the top three in a race. This is likely to be even more true in the last races. Indeed, though up till now everyone has been hunting for the prime spot on the line without worrying too much about what the adversaries are doing, tomorrow proceedings will be a bit more complicated. There’s going to be some marking on the cards as the teams try to put penalties on their rivals. It won’t be a surprise to see boats colliding, especially as the forecasts are currently announcing a wind of between 12 and 14 knots” announced Christophe Espagnon, the mainsail trimmer.

    For the last day in Sicily, the organisers of the Extreme Sailing Series have just announced that the start of races initially scheduled for 1500 hours, have been moved forward to 1300 hours. As such the winner of Act 6 is expected to be announced at around 1600 hours.
