  • 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.

    The Indian has stirred. In tune with a low pressure system that he observed a few days, Sébastien Josse is currently making headway in 25 to 30 knots of breeze along the edge of the ice exclusion zone. Less than 600 miles from the longitude of Cape Leeuwin (SW tip of Australia), conditions are set to get tougher, with a bumpy road ahead for the skipper of the Mono60 Edmond de Rothschild.

    Contacted by Vendée Globe Race HQ in Paris this morning, Sébastien admitted that this bad weather forms part of the scenery in this race and you have to endeavour to deal with the situation in a seamanlike fashion. “We’re beginning to get into the teeth of the matter with a series of low pressure systems, the likes of which we haven’t seen until now… but this is what it’s all about, it’s a circumnavigation of the world, it’s the Vendée Globe!” he explains, before describing the atmosphere: “I have 25 to 30 knots of breeze with a four-metre swell. Today’s programme involves dealing as best I can with the low pressure system and also paying attention to the ice zone, which has to be negotiated properly. There’s no way out and I’m trying to slip along between the two. Today, I’m expecting to… go sailing (laughs)! The wind will build, I’ll have to reduce my sail area and I’ll certainly have to gybe.” At midday this Monday, the skipper did indeed put in a gybe, which is an incredibly tricky manœuvre in such strong winds, requiring the utmost concentration and a great deal of composure.

    Almost everyone, without exception

    In truth, the skipper entered into the thick of things last night, when he experienced up to 40 knots of wind. Meantime, further up the racetrack, the ‘great escape’ continues. Armel Le Cléac’h has just passed the longitude of Cape Leeuwin, whilst Alex Thomson, who acknowledges that he’s eased off the pace a little, is now 100 miles shy of the leader. Though this top duo is still racking up high average speeds, they haven’t yet had to negotiate any strong gales. The same cannot be said for the bulk of the chasing pack, who have all been scooped up by it over the past few days from the South Atlantic to the Indian Ocean. This first big test has led to a certain amount of freestyling for some as well as a catalogue of damage, albeit minor fortunately, as well as the breakage of Spirit of Yukoh’s mast, which resulted in the retirement of its skipper, Japanese sailor Kojiro Shiraishi.

    A second night in the storm this Monday

    At the present time, it’s Sébastien Josse whose alone in experiencing the worst the low pressure system has to offer with another 12 to 24 tricky hours ahead. “I’m in the low pressure system: last night I was sailing under three reefs (in the mainsail) and J3 (the smallest of the headsails). Right now, I’m still picking my way through the bad weather with an average of 30-knot winds. At the moment, I’m under downwind staysail with two reefs in the main and I’ll have to reduce the sail area again later today. Last night I was reaching but further down the track I’ll have 40 knots of downwind conditions. I’m already in the mindset of a guy whose sailing in strong winds, the worst of which is to come, albeit from a different direction: last night I was making headway 80 degrees to the wind with 35 knots of breeze and tonight I’ll be 140 degrees to the wind with 40 knots, and maybe even more in the teeth of the low pressure system.”
