  • 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.

    After the ordeal of the Doldrums, Sébastien Josse and Charles Caudrelier were the first to cross the equator on Thursday at 2035 GMT, after just 7 days 8 hours and 35 minutes of racing from Le Havre; a spellbinding time in double-handed configuration and reminiscent of the record time sailed fully crewed. The two men are now hammering along, heading due South as they approach the latitude of Recife, which they’re likely to pass this evening. Still boasting a lead of over 70 miles (130km), the crew of Edmond de Rothschild are going flat out in the south-easterly trades, despite being hosed by the spray washing over the deck. It’s the same scenario for Sidney Gavignet and Damian Foxall aboard Oman Air-Musandam, which is further over to the east, ready to pounce the minute there is an opportunity to make up ground on the leaders.

    Though the two 70’ trimarans in the Transat Jacques Vabre are already making headway offshore of Brazil, the suspense of this ‘oceanic duel’ still has some great hours ahead of it. In fact, with over 1,500 miles (2,780km) to go before they reach the port of Itajaí, some 700km to the south of Rio, the two duos, who have been keeping up the pressure on one another for the past eight days, will have to display nerves of steel and make sure they’re physically strong enough for this final sprint, which will require a fair amount of tactical finesse.

    A double-handed ‘run’ worthy of a Jules Verne Trophy

    Whilst the rest of the Transat Jacques Vabre fleet is continuing to make headway in the northern hemisphere, yesterday the two Multi70s crossed the equator within two hours of each other. Sailed double-handed for the first time since they came into existence, these 21m one-design trimarans have been throwing the speedos into turmoil since the start. Indeed the Edmond de Rothschild duo took 7 days 8 hours and 35 minutes to cross the equator from Le Havre and just 6 days 11 hours and 35 minutes from the north-west tip of Brittany (St Mathieu). This latter pace is highly reminiscent of the time racked up by Groupama 3, helmed by Franck Cammas, during his first Jules Verne Trophy attempt in 2008. His crew of ten completed the course from Ushant to the equator in 6 days 6 hours and 24 minutes.

    Pedal to the metal in the trades

    “We’ve picked up speed in 25 knots of south-easterly breeze and we’re making headway at 25-30 knots on fairly flat seas,” Charles Caudrelier admitted this morning. “At this pace, we’ll be off the Recife headland in 12-13 hours (17-1800 GMT this evening) at which point it should become pleasant again.” Decidedly chirpy today, skipper Sébastien Josse echoes this sentiment: “All’s well! We’re in the sunshine making good speed and soaked to the skin, but that’s par for the course: you don’t get something for nothing! The central hull is creating a constant jet of water and the minute you come out from under the cuddy, you’re soaked.”

    With a few sail adjustments according to the intensity of the tradewinds, it’s the piloting that is the current focus aboard the trimaran fitted out by Baron Benjamin de Rothschild. In these conditions, the major options are a thing of the past. Right now they need to make headway to the south as fast as they can and keep their rivals at a safe distance.

    Oman on their tails

    And theirs is a tough rival! By shifting across to the east as they negotiated the Doldrums, the ‘challenger’ has managed to reduce its lateral separation in relation to the leader, but for now it doesn’t appear to be benefiting from a very significant advantage either in terms of angle or speed.

    However, Sébastien and Charles are remaining vigilant. “We weren’t sparing of our efforts last night” the skipper admits. “We were on the attack and taking it in turns on a regular basis to get the most out of the boat. With their easterly separation on exiting the Doldrums, we still had a fight on our hands with Oman and we wanted to ensure we came out of the zone well ahead of them.”

    Gearing up for a breathtaking finish

    Though the conclusion of this duel is still a long way off (ETA late Monday to Tuesday), the general opinion is that to the south of Cabo Frio, the weather situation is getting complicated and, some would say ‘highly random’ over the final miles to Itajaí.

    Ranking on Friday 15 November at 1530 GMT:
    1. Edmond de Rothschild (Josse-Caudrelier) 1,507.8 miles to go /24.30kt average over 2 hours
    2. Oman Air-Musandam (Gavignet-Foxall) 69.8 miles behind the leader /26.9kt average over 2 hours
