  • 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.

    Clean start! As scheduled, the Transat Jacques Vabre fleet set sail this Sunday 5 November at exactly 12:35 UTC from the foot of the Cap de la Hève, just off the cliffs of Sainte-Adresse. In a medium W to NW’ly wind of around twenty knots and rough, choppy seas, the 37 competing duos set a course for Salvador de Bahia in Brazil, some 4,350 miles away. At the helm of the Maxi-Edmond de Rothschild, Sébastien Josse and Thomas Rouxel got off to a safe start.

    The weather for the first few hours of racing promises to be bracing and the Edmond de Rothschild duo won’t have the luxury of a period of wait-and-see before they get down to action! Indeed, though the exit from the English Channel is likely to be behind them by tomorrow morning, once Ushant is in the wake of the Maxi Edmond de Rothschild conditions will deteriorate ever further until a cold front rolls through on Monday night through into Tuesday in the Bay of Biscay.

    In the English Channel, the angle and strength of the wind and the sea state might appear ideal for powering up, but Sébastien Josse and Thomas Rouxel have opted to tackle this start of the race with an altogether different mindset coloured by a more long term vision: “Around twenty knots, 1.5 to 2-metre waves and probably a long reach as far as Ushant with a few changes of headsail on the cards, On paper, conditions will be favourable for immediately racking up an average speed of around 40 knots. However, amidst the maritime shipping, the proximity of the coast and the negotiation of the TSSs, we don’t think it would be a reasonable or clever policy for the start of a race.”

    Start declarations

    The last boat to leave the dock in Le Havre, the Maxi Edmond de Rothschild cast off at 09:30 UTC. Three hours prior to the race start, Sébastien Josse and Thomas Rouxel shared their final thoughts with us.

    Sébastien Josse, skipper of the Maxi Edmond de Rothschild: “ Conditions are rather favourable for going fast, but our objective isn’t about getting a record. Primarily the focus is on getting to Bahia as best we can and in the first 2 days it’ll essentially be a question of hunkering down as we don’t yet have much experience in such conditions. It’s the Maxi’s first race. We know we’re going to encounter conditions we haven’t really had in training, but it’s all about trust and we’ll try to go about things in the right way. I’m happy to be doing this first race with Thomas as we share a mutual trust and he’s totally tuned in, he has a lot of experience to fall back on, he’s very serious and very focused. It’s his first start on a big boat and I’m quite confident that we can step up to the plate.”

    Thomas Rouxel, co-skipper of the Maxi Edmond de Rothschild: “The start is going to be pretty complicated with all the other boats. We hope the zone will be nice and clear. Once we’ve crossed the line, we should make the Etretat mark on a single tack so that’s good. We’re quietly confident. We’ll set off gently and in principle we’ll be sailing pretty close-hauled so we won’t be flying on the initial tack. We won’t attack from the get-go so it’ll be safer. The routing is indicating around 8 days to Bahia and we should pass offshore of Ushant in the middle of the night and the Azores the day after so it’ll be quick. I’m very lucky to be doing my first Jacques Vabre on a boat like this and I’m very pleased to be here as I’ve been wanting to do the Transat Jacques Vabre for a long time. It’s a great race so I’m going to try and savour this time and give my all.”
