  • 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.

    For days, observers had been announcing a fairly inactive doldrums, which was showing the Vendée Globe sailors its best side. But that was without banking on the magic’ of this famous Inter-Tropical Convergence Zone, as Sébastien Josse described it this lunchtime, or its most unpredictable nature… Third in the 08:00 GMT ranking this morning as he entered the doldrums, Sébastien Josse had slipped down a place in the 17:00 GMT position report and was 97 miles shy of leader Alex Thomson.

    After eight days of racing, the head of the Vendée Globe fleet is already sinking its teeth into the doldrums, which is a belt of low pressure spanning a few hundred kilometres, which wraps around the Earth near the equator. The solo sailors valiantly began picking their way through the mire in the early hours and have since been trying to pinpoint the fast route out of this zone, where it rarely does any good to dawdle.

     

    Round 1, it’s working out to the East!

    “There we have it. We’ve entered the doldrums. At daybreak, Vincent (Riou) and I got caught in a squall. The wind rotated through 360 degrees and since then we’ve been pinned to the track. Right now, it’s calm and there are 2 knots of breeze. The sea is glassy with a one-metre residual swell. The sky is colourless and it’s drizzly.” These were Sébastien Josse’s words at the Vendée Live at noon, as he described the atmosphere in which the skipper of Edmond de Rothschild was battling to make headway.

    Traditionally more friendly in its western sector, where it has less of a hold theoretically, the Inter-Tropical Convergence Zone, alias ITCZ, hasn’t yet finished serving up its surprise menu for those who dare to venture into its waters! Indeed, after ten or so hours in the thick of the system, the results are very clearly favouring those on an E’ly trajectory like Hugo Boss, which has managed to maintain some average speeds of 12 knots, whilst its closest rivals have been struggling to exceed 5 knots. This significant differential has had direct consequences on the ranking. Indeed, at 17:00 GMT, the skipper of Edmond de Rothschild had conceded 97 miles to the Briton, compared with 32 miles this morning at the gateway to the doldrums.

    Another of today’s smooth operators is SMA which, thanks to a similar trajectory to that of Alex Thomson, is right back in the game in 5th place.

    Being opportunist to make headway South

     

    Seeing such hard-fought miles slip away in a matter of hours is naturally annoying for the competitive soul that is Sébastien Josse. That said, the skipper of Edmond de Rothschild, for whom this certainly is not his first negotiation of the doldrums, preferred to put things in perspective: “Since this morning, I’ve changed more sails than I have since the start of the race and it’s not over yet! It’s impossible to know where the wind will kick back in. You have to be opportunist… A squall may form and empty in six hours. Right now, the die is cast… Afterwards, even if we don’t come off well in the doldrums, it’s a long race and there’s time to get back in the game.”

    Despite this slow-down, which he’ll naturally be pleased to put behind him, the five-arrow skipper was managing to reap some benefits: “For several days, given the average speeds we’ve been making, it was complicated to go up on deck and check over the boat. However, I made the most of the calm conditions this morning to carry out a good inspection and check that everything was in order. I also treated myself to a nice little shower in the fine rain of early morning…”

    According to the latest meteorological estimates the exit lies at around 3°N. Whether you’re positioned a little over to the East or further over to the West, this evening’s slogan remains the same on all the monohulls: it’s important to make the best possible compromise to make headway South.
