  • 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.

    In the footsteps of Columbus.

    This Sunday 18 March 2007, Gitana 13, the latest addition to the already three hundred-year-old dynasty of Rothschild boats, set off on its first challenge of the year in the Route de la Découverte Cadix-Salvador (Discovery Route Cadiz - San Salvador). The catamaran crossed over the starting line at 9 hours 7 minutes and 8 seconds UT.

    This Sunday 18 March 2007, Gitana 13, the latest addition to the already three hundred-year-old dynasty of Rothschild boats, set off on its first challenge of the year in the Route de la Découverte Cadix-Salvador (Discovery Route Cadiz – San Salvador). The catamaran crossed over the starting line at 9 hours 7 minutes and 8 seconds UT.

    This most unusual feature of this race is that each boat departs at the moment adjudged most opportune by its crew and supporting technicians, primarily on the basis of the weather conditions. Flying the flag for the Gitana Team is a twelve-man team led by Lionel Lemonchois, the redoubtable winner of the Route du Rhum 2006.
     
    The Discovery Route  Cadiz – San Salvador is so-named in evocation of the first voyage made by Christopher Columbus, from August to October 1492, on behalf of the Spanish royal family. He was trying to reach Asia by taking the western route – as the existence of America was not yet known – without having to go around Africa or cross the territory of the Turks.

    As a matter of fact, the itinerary followed by Gitana 13 should more or less follow that of the famous 15th-century navigator, namely passing well to the south of the orthodromic (direct) route. At the time, this course made it possible to avoid the Portuguese ships, the great rivals of the Spanish fleet. These days, this route, which involves passing by the Canaries with the main island on the starboard side, has the main advantage, as it did in days gone by, of drawing maximum advantage from the trade winds.
    As for the crew of Gitana 13, their determination and enthusiasm is every bit as impressive as that of the sailors of yesteryear. But there’s one sizeable difference: they are motivated not by the quest for gold and spices, but the taste for competition, the desire to excel as a team in the sport they love, and to experience a truly memorable adventure.

    In addition, it is probably worth pointing out that, unlike its 15th-century predecessors, Gitana 13’s crew contains no bombardiers, coopers or notary.

    Finally, there is one further key point to bear in mind: the record being targeted by the crew was set in 2003 by the American Steve Fossett, on Playstation: 9 days, 13 h, 30 m, 18 s.

    Weather update from Meteo France’s Sylvain Mondon, Sunday 18 March, at 09.00:

    Inner part of Bay of Cadiz: low easterly wind of 3/6 knots. Heading further south, the breeze will freshen up rapidly with the wind from the Straits of Gibraltar to 23/26 knots departing left to the northeast to the south of 35N the wind will die down to 17/21 knots north to northeast, then to 15/20 knots on the approach to the Canaries.
    Difficult passage by the Canaries to cross the windless zones with the wind from the archipelago.
