  • 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.

    So far and yet so near.

    It’s tight, very tight… It’s hard to draw any other conclusion about the state of the Vendée Globe 2008-2009 fleet on this 19th day of racing, which has managed to bunch together some of the fiercest contenders in a long stampede at the front of the fleet. Loïck Peyron hasn’t made good his escape as yet and has switched from hunter to hunted and back to hunter again at the mercy of the ranking. Currently in the wake and in sight of Sébastien Josse, the skipper of the monohull equipped by Baron Benjamin de Rothschild is still in the clutches of a capricious zone and is putting duty before everything else in the negotiation of Saint Helena.

    He will have to choose between a route taking him as close as possible to the zone of high pressure, on the edge of the precipice, or a more prudent but much longer option. And though this is a particularly interesting situation for the racing car enthusiast from La Baule, it may well prove decisive for the next stage in the race and the entry into the south. It’s a true Hitchcock scenario and the observers are relishing it…

    Your turn, my turn, your turn, my turn! After conceding the leadership of the fleet at the 1600 hour ranking yesterday to Sébastien Josse, the skipper of Gitana Eighty snatched back pole position overnight, prior to having it chipped away from him again by the skipper of the British monohull. However, beyond the waltz for the top spot, you have to watch the entire dance floor to realise that it’s no longer a two-step in action in the southern Atlantic, but rather a collective boogie. In fact 9 competitors are within 46 miles of each other, which surely must be a first at this stage in the Vendée Globe; proof if need be that the sixth edition of the event is still more reminiscent of a regatta race rather than a marathon. The frontrunners can almost smell the meals being prepared in their rivals’ mini galleys, each of them logically watching each others moves. Loïck Peyron, in particularly fine fettle this Friday, looks back at the encounters he had early this morning: “After losing time under the famous cloud yesterday, I’ve really got back into the thick of the action. In fact I’ve just been speaking with Seb (Sébastien Josse) and I can see Armel (Armel Le Cléac’h, 3rd on Brit Air). It’s quite nice to be sailing within sight of everyone”. There’s no question of making good his escape right now, the monohull in the colours of the LCF Rothschild Group being not only surrounded but also, and above all, subject to the same scenario as the competition: “Our monohulls being fairly similar in terms of performance, it’s rare to be able to escape. Having said that it’s true that since the start, there have been two or three tricky passages which have favoured those behind. The opposite would be most welcome right now so we can benefit too!”

    However, before they can take off again, they will have to find a great strategy to get out of the current weather situation. The Saint Helena High is still continuing to lay down the law and is keeping the solo sailors in suspense, even though most of the fleet have chosen their exit routes now. Leading the way, the top trio, of which Gitana Eighty forms part, is picking its way due south, whilst those behind and further to the west, Jean-Pierre Dick and the Englishman Mike Golding have shifted back over in the past few hours to remain in contact. Positioned over to the east, out on his own, Jean Le Cam has opted to be the first to traverse the zone of high pressure and he is also hoping to be the first out. Questioned about the various strategies, the skipper of the monohull equipped by Baron Benjamin de Rothschild was pertinent in his analysis: “We’re currently faced with a kind of gamble which is making all of us aim for a zone where there isn’t any wind for the time being. The onus here is on not distancing ourselves too far from the direct route and on finding the right point to make the long turn. The inside bend is full of gravel and the outside edge is clear but increases the distance to be travelled. It’ll be interesting to see who gets out first!”

    It’ll be a while yet before they reach the exit, with the forecasters currently banking on Sunday. In the meantime, the end of today should see a strengthening E’ly breeze, forcing the solo sailors to be opportunist at all times. Numerous manœuvres and sail changes will also be the order of the day in this upwind navigation. At the heart of the zone of high pressure though, the wind will drop dramatically and the skippers will have to carve out their own route to ‘deliverance’: “The end of this day will be a bit difficult with wind forecast. We’ll have to reduce the sail area and then rehoist it all tomorrow. We’ll certainly be close to the eye of the anticyclone at that point, and not far at all from the tear ducts…”, said Loïck Peyron during today’s radio session. There will doubtless be some tears for some and given the risk of further bunching across the fleet, they’ll certainly be able to hear each other crying. The suspense continues…
