  • 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.

    Off and away.

    When the eighth Route du Rhum got underway at 13:02 on Sunday, the 74 solo sailors set off in a light westerly headwind blowing 5-8 knots. For these first miles in the Channel, the two Gitanas erred on the side of caution by choosing to take up a position windward of the fleet. Gitana 11 was 3rd past the Cape Frehel mark, the first reference point…

    When the eighth Route du Rhum got underway at 13:02 on Sunday, the 74 solo sailors set off in a light westerly headwind blowing 5-8 knots. For these first miles in the Channel, the two Gitanas erred on the side of caution by choosing to take up a position windward of the fleet. Gitana 11 was 3rd past the Cape Frehel mark, the first reference point on the race’s route.

    It’s not easy to pull right away from that starting line and finding a fresh breeze to leave that cathartic cannon sound far behind! Thierry Duprey du Vorsent and Lionel Lemonchois succeeded in ensconcing themselves in the middle of the fleet of competitors, not to mention the numerous spectator boats, to depart in the face of a light west to north-westerly towards the Cape Frehel mark. While Michel Desjoyeaux, winner of the last Route du Rhum, took up pole position by slipping to the bottom of the line, the two Gitanas opted for a more cautious route to the north of the fleet in order to pick up on clearer wind for this first part of the course. For although the ranking at the first and last-but-one mark before arriving in Guadeloupe was far from crucial, it at least allowed a good number of launches and dinghies to be left behind, lowering stress levels heightened by the chance of a collision.

    Amidst a light wind that was quite unstable in terms of direction, the primary aim was to find the balance between high performance and safety: by avoiding having to make too many manoeuvres, Lionel Lemonchois (Gitana 11) was able to swiftly find his rhythm, as was Thierry Duprey du Vorsent (Gitana 12). Consequently, by the fateful passage before emerging from the Channel, the two Gitana Team skippers had managed to strike the right balance between a good position and a gradual build-up. As the first night tends to be decisive as regards the correct handling of a light and highly unstable wind so as to exit the Channel at the head of the pack… According to the weather info, the trimarans that arrive first off Ushant will find it easier to take advantage of a stern breeze to accelerate towards the Azores, the first really severe test of this Route du Rhum. But the particular situation which reigns over the Atlantic, with a large low-pressure front to negotiate to the north, suggests the race will be extremely tight right up to the finish at Pointe à Pitre, and particularly fast too… The two Gitanas have already waved goodbye to the first obstacle (the start): now they need to find a safe way out of the first trap, the Channel!
