  • 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 6th November, ten trimarans will be setting out from Le Havre on the start of the last race of the season – the two-handed Transat Jacques Vabre. A 5,190 mile race across the Atlantic to Salvador de Bahia via Ascension Island. Gitana X withThierry Duprey du Vorsent and Erwan Le Roux, and Gitana 11 with Frédéric Le Peutrec and Yann Guichard will be rallying the port in Normandy on Wednesday evening.

    The two trimarans cast off from their home port of la Trinité sur Mer yesterday afternoon, Tuesday bound for Le Havre. The deadline for arriving in Le Havre is midday Friday 28th October but most of the boats based in southern Brittany have preferred to set out earlier than actually necessary in view of the series of low pressure systems heading for Europe. Strong winds are not forecast (steady by manageable at 15-35 knots) but the sea is likely to be rough. Waves at the entrance to the English Channel are already more than six metres high and in view of the two perturbations brewing up and scheduled to reach the zone on Thursday and Saturday, the phenomenon will be accentuated with a S/SW flow for five days or so. From the archipelago of Madeira over to Ireland, the state of the Atlantic Ocean is highly chaotic. This series of lows suggests that autumn is truly on its way !

    To the point that the long-range weather forecasts indicate two new perturbations coming in from the Gulf of Mexico, passing over Newfoundland, and fortunately loosing a little of their energy by next week. As the tropical zone is very hot, this gives rise to very low pressure systems which seek their source in the Caribbean, climb north to round the Bermuda high, before moving up along the east coast of the United States and running into the polar winds of Newfoundland and dart off towards Europe between 40° and 50° north. The series of cyclones over New Orleans and Florida is linked to this phenomenon. For the time being, the Atlantic perturbations have not yet hit France full on as they have been de-routed NE by a large high pressure system over Germany. Never the less, as a result of repeatedly running into highs, it is highly likely that the weather in Normandy next week be much more perturbed than it has been of late. 

    Tough going ahead

    Meteorological explanations of this sort support the fact that the two-handed Transat Jacques Vabre is likely to be a tough edition this time round. Tough because the Atlantic will be chaotic off Ushant and Cape Finisterre, tough because the Azores High is a long way off being back in place by the middle of next week. All of which means that the depressions will be rather low in latitude, generating westerly winds and that the NE trades will be very low and not that active. The first part of the race is going to be physical, difficult from a tactical point of view and hard on the gear. This could be anyone’s race until the Cape Verde islands are behind the fleet anyway. 
    This end-of-season race is of capital importance in determining the rankings in the Multihull Championship. It counts triple (with a weighting factor of 3 on the scoreboard). If Frédéric Le Peutrec and Yann Guichard (Gitana 11) are to hold onto their third place, they have to finish ahead of Michel Desjoyeaux (with whom they are currently equal on points). If they are to make it to second place, they have to make sure that there are two boats between them and Franck Cammas if they win the race, a minimum of three trimarans if they make second or more. For Thierry Duprey du Vorsent and Erwan Le Roux (Gitana X), finishing already gets them to sixth place in the Multihull Championship. But, if the weather is a rough as current forecasts indicate, then they are likely to gain one place at least over Armel Le Cléac’h holding just an 11 ½ point lead over them. Both boats will be in Le Havre for ten days or so which gives them the opportunity to take stock of the scale of the climatic challenge and to participate in the activities which are livening up the Norman harbour town throughout the week.
