  • 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.

    A day off the pace for Edmond de Rothschild Group.

    In the Extreme Sailing Series, more than elsewhere seemingly, nothing is ever a done deal. As such, after yet another day dictated by light and extremely random conditions, which were perhaps borderline as regards top-level racing, the hierarchy has been turned on its head. For the men of Edmond de Rothschild Group who, despite a victory in the second race of the day, lamented a series of poor rankings, the sentence is a heavy one. Third yesterday, Pierre Pennec and his men are lying in sixth place tonight in the provisional standing. However, just a handful of points separate the catamaran fitted out by Baron Benjamin de Rothschild from her rivals, which just goes to show that anything is still possible. The weekend ahead promises to be extremely tense, as the crews will need to put up a solid performance right up to the final race if they are to shine in this eighth act of the season 2011.

    The wind was forecast to be more generous along the coast of Andalusia this Friday. However, decidedly the wind gods are keen to thwart the forecasts and do things their way and the Extreme Sailing Series fleet ended up once again having to deal with nerve-racking light airs: “The easterly wind, synonymous with a few additional knots, wasn’t far off today. Indeed it even flirted with the race zone but was unable to establish itself there. Evidence of this was that the eleven one-designs had to get used to a swell which generally accompanies the much awaited easterly breeze during races contested outside the port stadium.”

    Manhandled throughout the afternoon, the men of Gitana Team weren’t waffling on their return to the dock, as is demonstrated by Hervé Cunningham’s reaction: “It was difficult today aboard Edmond de Rothschild Group. We were pretty much in on the action outside but the minute we came into the port for the stadium races we couldn’t get into our rhythm. We found it hard to pin down what we wanted to do. Either we didn’t manage to position ourselves correctly on the line, or when we were well positioned we didn’t have the right angle to power up. Finally, when we did manage to bring the two parameters together (positioning and course) we ended up getting smothered by the OCS boats (boats which overshoot the start line). To sum it up, nothing really went our way. Some days are like that!”stated the bowman, without abandoning the good humour and positive attitude which characterises him: “Of course you have to draw lessons from a day such as this, as you can see that despite the random conditions, some of our rivals did really well. However, it’s important not to fret and think you need to go all the way back to square one. Today’s results are a reflection of one bad day that’s all!”

    Philippe Mourniac, who’s been supporting the crew of Edmond de Rothschild Group as their sports coach since the previous event, also gives us his on-the-spot analysis: “Generally, because of the race zones on offer, we know that the Extreme 40 races can sometimes turn into a raffle. And in the conditions we encountered today, namely a light, very shifty wind, then a swell which picked up due to the arrival of an easterly breeze, it’s even more of a lottery! In sailing, there is always an element of success to take into account and I can objectively say that the team’s quota of success was clearly lacking this Friday” conceded Philippe, before casting his mind to the next few days. “The wheel is spinning and you have to remain confident, analyse what didn’t work and then start out with a clean slate tomorrow. We know that on this circuit, you must never get carried away when you’re on a winning streak, but similarly you mustn’t think that everything is lost either. The important thing to remember is that there are two days of racing to go and that the crew is still in contact with the leaders despite today’s events. Everything will be decided on Sunday and the boys know just how to handle these highs and lows.”

    The provisional ranking for the Almeria Grand Prix has seen its fair share of leaderboard changes on this third day. The English team on GAC Pindar, fifth yesterday, have moved up into pole position, whilst the Swiss team on Alinghi have jumped five places to end the day in second position. In the same way, the Omani boat, The Wave Muscat, has also made it into the Top 3. In contrast, the men of Edmond de Rothschild Group have taken a hit after an unsuccessful day, dropping down three places. However, the crew that’s suffered the biggest loss is skippered by Ben Ainslie who, despite leading yesterday, is lying in eighth position this Friday. This position waltz is not surprising though, given the similar level amongst the fleet and the particularly honed line-up after seven confrontations this year so far. In this context, Pierre Pennec and his three crew know that they’re going to have to raise their game and get back into the rhythm which was lacking today.

    Rendez-vous tomorrow at 1400 hours for the start of racing, with the hope that the wind gods will finally serve up some fine sailing conditions for the eleven catamarans competing in the Almeria Grand Prix.
