  • 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.

    Faultless performance by Edmond de Rothschild in Valencia.

    The Route des Princes has kicked off on a high for Gitana Team. Tied on points at the top of the leaderboard last night after the first three Valencia inshore races, the trimaran fitted out by Baron Benjamin de Rothschild dominated play today to take a comfortable win ahead of its rivals. Winners of all three races contested this Saturday, Sébastien Josse and his seven crew ruled supreme to treat Edmond de Rothschild to the first victory in this European Tour for multihulls. However, the men of Gitana XV will only have a short amount of time to savour this first place because tomorrow they’ll be switching exercise and atmosphere with the start of the first of the event’s offshore legs; an 800-mile race from Spain to Portugal, the finish of which has an ETA in Lisbon of 12 June onwards.

    For the second day of inshore racing in Valencia, the weather conditions were totally different. Indeed the cloudy, stormy skies of yesterday gave way to glorious sunshine and a fine westerly breeze of 15 to 25 knots. It proved to be a winning scenario for the crew of Edmond de Rothschild, who were especially inspired and at ease in this steadier breeze. With three victories in as many races, Sébastien Josse and his men ruled supreme, putting up a truly faultless performance: “The wind conditions we were racing in seemed easier to me, as you immediately feel the force of them on the boat. The crew were up for it and everyone knew exactly what they had to do, with Sébastien Col calling tactics, Charles Caudrelier doing the nav and the trimmers sparing no effort. My seven crew did a fantastic job,” admitted the skipper of Gitana XV before going on to discuss their victory: “We’re really very happy as this result means that the hard work has paid off. We’re spending a lot of time on the water, but when you’re in the learning phase, as is the case for me on the multihull, it can be difficult to get feedback on how you’re doing sometimes. To win this first inshore race has lifted the whole team’s spirits and even though we’re going to have to follow through on this performance for the rest of the event, we’re going to take the time to savour our first place.”

    With this Spanish victory, the men of Gitana Team have proved that they are going to be a force to be reckoned with throughout the three weeks of competition that lie ahead. In tonight’s final ranking, after six races, they have outdone Spindrift Racing and Virbac Paprec. In this way, Edmond de Rothschild has been awarded 10 points, whilst second and third place pocket 8 and 6 points respectively: “The points we scored today are obviously important, but you do have to bear in mind the fact that the points for the inshore races for the whole event amount to 40 points out of the total of 190 overall in the Route des Princes, that means the inshores are worth 21% of the points”, Sébastien Josse reminds us.

    Tomorrow the Route des Princes fleet will leave Valencia and its Hispanic shores on the first offshore leg bound for Lisbon. This 800-mile course will kick-start this European tour, linking the Mediterranean to the Atlantic coast of Portugal. With a little less than 24 hours from the start, Charles Caudrelier, navigator on Edmond de Rothschild, describes the physiognomy of this first leg: “We’re only certain of one thing right now, we’ll have to contend with headwinds! With regard the strength of the wind, that will depend a bit on timing. For now, we’re going to have to climb around 60 miles North of Valencia to hunt down a mark off the city of Benicarlo. As there’s very little wind to the North, followed by little air 50 miles to the South of Valencia that night, that section could be very slow. The later we are reaching the weather systems to drop southwards, the lighter the wind will be. It’s pretty tough to come up with any kind of clear plan this evening, as Race Management hasn’t yet made a definitive decision about the course, though this return leg will have an influence on the next stage. For the time being, we’re watching a westerly breeze, which appears to have settled to the South of Valencia and if we manage to hook onto that before it fades away, we could make headway towards Gibraltar. After this passage, once we’re through into the Atlantic, we should be able to link onto an upwind section again, with a ridge of high pressure to be negotiated. This race promises to be strategically complicated. For now, the routing software is pretty varied and our arrival in Lisbon could be played out this coming Wednesday or Thursday.”
