  • 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.

    Gitana 13 attacks the North Pacific crossing..

    The stopwatch is back in action aboard Gitana 13. On standby in San Francisco since 28th February – the completion date of La Route de l'Or-, the maxi-catamaran equipped by Baron Benjamin de Rothschild set off this Saturday 29th March at 22h45'45” UT, for a record attempt between San Francisco and Yokohama.

    The stopwatch is back in action aboard Gitana 13. On standby in San Francisco since 28th February – the completion date of La Route de l’Or-, the maxi-catamaran equipped by Baron Benjamin de Rothschild set off this Saturday 29th March at 22h45’45” UT, for a record attempt between San Francisco and Yokohama.

    The new holders of La Route de l’Or (New York – San Francisco), Lionel Lemonchois and his ten crew are today tackling the North Pacific crossing. And, in order that the men of the Gitana Team rack up another victory they’ll need to make Yokohama, Japan, in less than 14 days 22 hours 40 minutes and 41 seconds. The latter is the current reference time set by Olivier de Kersauson and his team aboard Geronimo since 27th April 2006.

    Eleven men have embarked on this second record
    “The crew has been slightly modified in relation to that of La Route de l’Or, since Jacques Vincent, Jean-Baptiste Epron, Cyril Dardashti Stefan Fodor and Kojiro Shiraishi are joining us. There were ten of us onboard Gitana 13 between New York and San Francisco, but there will be eleven of us for the North Pacific crossing. Personally, I shall have a greater involvement in the weather since the crew no longer has an appointed navigator aboard” explained the skipper of Gitana 13, prior to giving us a more in depth look at the 4,500 miles which lie ahead: “According to the latest weather information, we should benefit from a fairly quick start for the first few days and once we’re out of San Francisco Bay, we’ll hit a good NW’ly air flow. The first part of our crossing is shaping up rather nicely but, for the time being, things aren’t very established for the second half, particularly with the lows, which are piling in one after the other off the Japanese coast.”
    The presence of the Japanese sailor Kojiro Shiraishi, who was 2nd in the Velux 5 Océans 2006-2007, will be a considerable asset for the crew of the 33 metre maxi-catamaran; especially at the approach to the Japanese coast, renowned for its complexity.

    The weather is always a tricky element and the Gitana Team are keeping to their usual routine and will once again be able to count on the talent of Sylvain Mondon (Météo France). The router shows us the weather configuration for the start of this new record attempt: “Gitana 13 has set off at the rear of a front in order to benefit from a NW’ly breeze, currently blowing along the Californian coast. This wind, comprising an average of between 20 and 25 knots, may gust to between 30 and 35. It’s quite a feisty start but it will be interesting as the NW’ly wind angle will enable Lionel Lemonchois and his men to make good headway whilst gaining ground in the SW and then quickly the W, that’s to say not too far off the direct course. The start of the record promises to be quick but in the first 36 hours, the crew of Gitana 13 will have to negotiate a first high pressure passage. The Pacific Ocean is not a very appropriate name as this ocean has rather a bad reputation. Given its expanse, the systems which are circulating there often grow in size during their crossing.”

    A brief history
    The current record holder, the crew of Geronimo set off on this same attempt on 12th April 2006. Olivier de Kersauson and his men snatched the previous record set by Steve Fossett back on 23rd May 1996. The American adventurer set a reference time of 19 days 15 hours 18 minutes 9 seconds on the 60 foot trimaran Lakota.
    Ten years later, when Olivier de Kersauson and his ten men set off, the conditions reigning over the Pacific forced them to choose a very southerly route over the first few days at sea, distancing them from the direct course. Though Geronimo made the most of it to pass between the Hawaiian islands and rounded the mark of “Diamond Head” after 4 days and 19 hours. In so doing it established a new reference time between San Francisco and Honolulu (Hawaii). This passage off Honolulu, also proved to be an opportunity for Olivier de Kersauson and his crew to glean the record between Honolulu and Yokohama, previously owned by Steve Fossett, in 13 days and 20 hours.
    On crossing the finish line of this North Pacific crossing on 27th April 2006, after 14 days 22 hours 40 minutes and 41 seconds at sea, the so-called ‘Admiral’ racked up yet another win.
