  • 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.

    It’s been a weekend atmosphere at the head of the fleet in this 6th Vendée Globe. As such the first solo sailors have been sailing in the southern as opposed to the northern hemisphere since last night, after finally crossing the equator. Now in the grasp of a SE’ly tradewind, Loïck Peyron and his rivals are southbound on a long close-hauled tack following the western edge of the Saint Helena High. The skippers must now concentrate on benefiting from a spell of recuperation as the meteorological aspect of the southern Atlantic is set to rapidly give way to strategy.

    It was at 2100 UT last night that the monohull equipped by Baron Benjamin de Rothschild crossed the equator and led the fleet into the southern Atlantic. Loïck Peyron accompanied this passage with a nocturnal video as well as partly respecting a customary ritual: “We’re beginning to make headway upside down! It’s not the first time that I’ve passed the imaginary line but I’ve tried to respect the tradition of offering something to Neptune nonetheless.” A fizzy drink served as a liquid substitute, given the lack of wine or champagne flowing across Gitana Eighty’s decks.

    The group of ten at the front, led by Loïck Peyron, are now sailing in the southern hemisphere and the solo sailors are prepared for a few days wedged onto port tack in the SE’ly tradewinds: “There is currently 15 knots of wind and Gitana Eighty is fully stacked, ready for the long stretch of close-hauled sailing coming up. It’s slamming a bit but there’s not a lot you can do so it’s doubtless going to be a relaxing weekend…” admitted the sailor La Baule. However, in order that we aren’t misled by this notion, though the coming days are forecast to favour recuperation, attention will still be a top priority… Indeed, the complexity of the latest generation 60 foot Imocas and the shifting strength of the wind along the course will require the presence of the skipper on deck.

    It’s a round number… it’s been ten days that Loïck Peyron and Gitana Eighty have been skipping along in the lead of the Vendée Globe 2008-2009. Still credited with a lead of 24.4 and 38.7 miles over Sébastien Josse and Jean-Pierre Dick, in second and third place respectively, the frontrunners are managing to fend off their closest attackers. Questioned about his ‘outrageous supremacy’ during the daily link-up with the Race HQ, the sailor contested the expression used: “It’s not outrageous and sorry if some of you are tired of it… But without something you have nothing, and it doesn’t feel like I’ve eased off the pace since the start! The Vendée Globe is a race where things will be won or lost in the detail. That’s why you have to constantly keep your eye on all the detail. Today, all’s going well, I’m controlling. What comes as a satisfaction to me, is that when I want to go a bit faster than my friends, I’m managing to do that.” After 13 days at sea, the duo Loïck Peyron / Gitana Eighty, who had already proven their worth by winning the two solo transatlantic races contested over the past year, is working amazingly well, in perfect osmosis.

    As regards the weather, an observation of the satellite images supplied by Météo France confirms a slightly confused situation across the southern Atlantic. This begins with the Saint Helena High, which is usually more stable than its equivalent in the northern hemisphere – the Azores High -, but seemingly wants to complicate the solo sailors’ entry into the Deep South. The reason for this is a stormy low coming off Brazilian soil and dying in the system of high pressure, disrupting the latter in the process. Then, a second anticyclone, positioned off Uruguay, is pushing the disturbed air flow far off to the south, which may well complicate things a bit more for the leading group. 

    Finally, if we glance behind the monohull in the colours of the LCF Rothschild Group, we can see that the chasing pack, led by the Swiss sailor Dominique Wavre, were luckier than the frontrunners as they weren’t slowed by the Doldrums at all. Behind them though, the weather barrier is proving to be slightly more stubborn, which confirms that in the Inter-Tropical Convergence Zone, it’s the weather alone which decides how its guests are treated.
