  • 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.

    The breeze did indeed kick back with a vengeance this Wednesday on the race zone in Cowes. Proving to be rather timid on the fourth day of racing, the wind was a lot more virulent today. The extent of this was such that the Race Committee had to cancel the race schedule for the eleven catamarans in the Extreme Sailing Series, which is a first on the circuit. As such the provisional general ranking remains unchanged aside from a few minor details… In fact, last night the jury went back on the decision it made on Monday morning following the collision between Edmond de Rothschild Group and Artemis Racing.

    Whilst the Extreme Sailing Series fleet were preparing to rejoin the nautical arena off Egypt Point, the procession of dismasted boats returning from their races around the Isle of Wight just went on and on. However, the race committee, which had taken all the necessary safety precautions beforehand, opted to send the crews out onto the water under observation. Despite carrying a reef in the mainsail and the storm jib, the thirty knots recorded on the race zone forced the organisers to throw in the towel and cancel the races which had been planned.

    Tomorrow, the forecast is for boisterous conditions again and, if this is confirmed, between 24 and 28 knots of south-westerly wind are likely to sweep across the waters of the Solent. Will the Extreme Sailing Series fleet have to remain on shore for the second day running? Verdict at around 1500 hours local time.

     

    A dramatic turn of events: the Extreme Sailing Series jury goes back on its decision

    During the second day of competition at this Cowes Grand Prix, Edmond de Rothschild Group was the victim of a violent collision with Artemis Racing. The two catamarans were seriously damaged during the incident. Gitana Team’s préparateurs – Marie Dixneuf and Cyril Ducrot – worked flat out to repair the port bow which had folded 90°. It proved to be a tricky operation which required them to manufacture a whole new bow section, a very long procedure taking them through the night. Back down to business yesterday, Pierre Pennec and his men were awarded a redress of 19.4 points. Indeed the jury had concluded that the responsibility for this collision was down to Santiago Lange’s crew. However, last night, this same jury changed its mind. Following a request from Artemis to reopen the case, it concluded that they were equally responsible and chose to impose a four point penalty on the catamaran fitted out by the Baron Benjamin de Rothschild, whilst cancelling their redress of 19.4 points. Pierre Pennec, Hervé Cunningham, Thierry Fouchier and Christophe Espagnon reserve the right to lodge their own appeal.
