  • 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.

    A birthday in the forties.

    On this Monday 1st December, whilst the solo sailors in the Vendée Globe are attacking their fourth week of racing and celebrating their entry into the southern seas, Loïck Peyron is blowing out his 49 candles! Despite this grand event, the skipper of the monohull equipped by Baron Benjamin de Rothschild remained very discrete during the daily link-up with Race HQ. Too caught up in a gybing battle currently in play as the fleet make towards the Cape of Good Hope, it wasn’t until late this afternoon that the sailor contacted his shore crew. And though the majority of the leading group are now sailing in the forties, we have to admit that this year these latitudes are proving to have less of a ‘roar’ about them than usual.

    The arrival in the disturbed air flow of the southern hemisphere, where the conveyor belt of austral lows circulate one after the other from west to east, has been much awaited by the competitors in the Vendée Globe 2008-2009. This is perfectly understandable given that they have spent the past ten days or so patiently waiting for this day as they battled upwind at virtually 90°to the direct course. However, as everything comes to those who wait, it was on Saturday night that the frontrunners were finally able to hang a left towards the Atlantic ice gate. Since that time the head of the fleet has had to put in a succession of gybes in order to follow the slight shifts in the WNW’ly air flow and make best use of the corridor of wind in the vicinity. “The wind is very changeable. It’s oscillating between 22 and 25 knots with peaks at 28 knots. The pace of the swell isn’t very organised yet but that’ll come” explained Loïck Peyron to set the scene.

    In fact, to the north of the fleet, the high pressure of Saint Helena is still looming above them like the Sword of Damocles, whilst to the south, a band of light wind is also beginning to form. This is the reason that the solo sailors are having to put in a series of manœuvres: “We’re currently sailing in a band of pressure as the wind is lighter to the north as well as further south. The name of the game right now is to exploit the corridor of wind. I gybe when the wind fluctuates and leads me onto a tack taking me closer to the next mark. This succession of manoeuvres is rather tiring but that’s the price you pay to make headway.”

    Although the current configuration is only allowing the skipper of Gitana Eighty a small amount of respite, he’s nevertheless had time to open the presents deposited on board by his nearest and dearest before the start: “I have a big bag containing a mixture of birthday and Christmas presents. As a result I’ve opened a few presents today and of particular note was a present from my eldest daughter as well as one from Gitana Team: a small, remote-controlled helicopter!” However, performance is always key and the ship’s captain only wanted light presents. This decision was naturally respected and the sailor was very appreciative of this from the latitudes of the forties. Furthermore, on this special day, Loïck Peyron shared with us his pleasure of being back in the southern ocean. “That’s it, we’ve made it here! I haven’t been back here since The Race in 2001… There’s everything you need: the albatross, the swell… all that’s missing is the long sessions of slipping along on a reach as, for the time being, we’re not sailing a straight course yet.”

    Once again today, at the front of the Vendée Globe fleet, it’s all about compromise. Getting yourself far enough south to benefit from a steadier air flow, but not too far south, on pain of losing your credit. Today’s winner in this little game is Sébastien Josse. Indeed, at the 1600 hour ranking, the skipper of BT was continuing to lead and had even increased his lead over Loïck Peyron slightly, the British monohull 40 miles ahead.  Hot on Gitana Eighty’s heels, Yann Eliès is still on the 3rd step of this provisional podium.

    Atlantic ice gate ahoy

    This year, the race management of the Vendée Globe, headed by Denis Horeau, has opted to set eight safety gates for competitors in this 6th edition. Positioned in the Deep South, these virtual lines of latitude, which the solo sailors will have to respect at a given point, have been devised with a mind to anticipating risk. Indeed they will prevent the sailors from dropping too far south and will thus attempt to minimise any encounters with drifting ice or worse still, icebergs. It should be noted that these gates may be moved according to the results of radar observations performed by CLS Argos. The Atlantic ice gate is located to the south of the tip of Africa, at 42° South and between 01° and 11° East.
