  • 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.

    Since the race start on Sunday evening (GMT) from the Big Apple, the fleet competing in the Transat New York – Vendée has endured some tough times. In fact, despite fairly mild weather conditions for the start of this transatlantic sprint, it’s below the water that a number of dreams have been shattered. Yesterday, five of the fourteen competitors had to turn back and seek refuge in Newport, with the majority of them lamenting damage following collisions with a UFO (Unidentified Floating Object). To date, solely StMichel-Virbac has headed back out onto the racetrack, whilst Armel Le Cléac’h signalled his retirement midway through this afternoon. At the helm of Edmond de Rothschild, Sébastien Josse has also had his share of mishaps, though the latest addition to the Gitana fleet remains damage free. The Imoca60 fitted out by Baron Benjamin de Rothschild is in the game, at the head of the fleet since the opening miles of the race. At the 15:00 GMT position report, she was provisionally lying in third place in a fleet headed by Briton Alex Thomson. Faster over the past few hours, the skipper of Hugo Boss is leading the way towards the first low in the transatlantic sprint bound for Les Sables d’Olonne in France.

    Setting sail from New York is never easy. The shipping, the current, the fog, the fishing grounds and hence fisheries, as well as the icebergs a little further North, all make for a rather tense atmosphere for those who set off singlehanded. Fortunately, the weather has remained fairly tame since Sunday: “We had a pretty good first night with flat seas albeit with little visibility as there was a lot of fog,” Sébastien Josse explained on Monday at the midday satellite link-up. “We’re gently making headway and we’re about to link onto some transition phases in terms of the weather. That will generate a series of small manoeuvres, the focus of which will be some nicely timed sail changes.”

    However, this Tuesday morning had rather a different taste for the skipper: “I haven’t suffered the same misfortune as some of my rivals, who have had to turn back. That said, I have had my fair share of aquatic encounters and one big fish in particular – a shark I think – which got wrapped around the keel. I had to go in reverse to free myself from it. As far as the rest of it goes, the rudders played their role as fuses, but there sure were a lot of things across our route!”

    Despite all that, the sailor has managed to keep a few of the fundamentals on track: “The pace is how I imagined it would be… You never get bored on these boats! However, I did manage to get some rest last night, despite a few manoeuvres in a fairly shifty wind. Right now I have been 20 and 25 knots, the wind has lifted (become more favourable) and it should stay like that for around twenty hours or so. After that, we’ll have to time a gybe just right to home in on the low.”

    Low pressure straight ahead

    The trajectory takes the form of a nice straight line, due East, bound for Europe, but things will become complicated in the coming days. A low, three times as wide as France, is stretch across the path of the fleet. “Within the next 24 hours, we’re likely to be in the teeth of the system, with a gybe required to switch onto port tack for around two days,” he continues. “A secondary low has just joined up with the main low. The latter seems to be deepening and, for now, the grib files are indicating 35-40 knots with fairly heavy seas. However, the wind strength will really depend on when we hit the system. The quicker we get there, the better it will be!”

    Even though the weather and the battle with Hugo Boss, Maître Coq and PRB are encouraging the skipper to push hard, he has every intention of keeping a cool head: “Alex (Thomson) and Jérémie (Beyou) have really been on the attack since yesterday and Alex’s lead comes as no surprise. For my part, my primary focus is on the upcoming low. It’s important not to rush things as the skipper that comes out of this low with a boat in tip-top condition will already be in a strong position. This is particularly true given that our arrival in the Bay of Biscay has become more complicated since we set sail. The last few miles won’t be easy, with some ‘nice’ surprises in store.”

    More haste less speed is the expression that perfectly sums up the mindset favoured by the skipper of Edmond de Rothschild for this race. However, having covered more than 700 miles over the ground at an average speed of 16.6 knots since the start, Sébastien Josse certainly isn’t dawdling…
