  • 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 Gitana Team couldn’t have imagined a better start to the season… Full house for Gitana 13 in its record campaign and success for Gitana Eighty in its programme of races, with the notable inclusion of Loïck Peyron’s historic triple in The Transat, rewarding the work of the whole team. The fleet in the colours of the LCF Rothschild Group clearly has the wind on their tail and has no intention of stopping there!

    With almost the equivalent of a round the world in its wake, it’s time for a summer break for the maxi-catamaran in the colours of the LCF Rothschild Group. After six months sailing and as many record times gleaned by the crew of Gitana 13, the analysis is rather positive for Lionel Lemonchois’ men. Setting out from New York on 16th January 2008, the sailors of Gitana Team have successfully completed the series of records and reference times they were targeting: the Route de l’Or, the North Pacific Crossing and then the Asian tour from Yokohama to Hong Kong, via Dalian, Qingdao and Taipei.
    “Since we set out from the foot of the Statue of Liberty last January, everything has linked together very well, as much on a sporting level as a technical one. The reference time for the Route de l’Or was totally accessible since it was held by a monohull, but this first course proved no less demanding or complicated, with nearly 43 days at sea and the east to west passage of Cape Horn. Following that there was the North Pacific, where we beat the time set by Geronimo (Olivier de Kersauson’s maxi-trimaran) by nearly 4 days. Finally, we had our various Asian records which comprised a wealth of encounters both on the water and during our different stopovers” explained Lionel Lemonchois.

    On Saturday 14th June, the 33 metre maxi-catamaran was lifted out of the water, not far from Hong Kong, for a few weeks summer refit. Besides the rig, which will be replaced in its entirety, the crew of Gitana 13 will make the most of this downtime to redo the appendage coatings (rudders and centreboard), manhandled by the numerous encounters with drifting fishing nets in the China Sea. It will also be an opportunity to perform a complete check-up of the boat; a necessary general validation session after sailing over 21,000 miles in, at times, harsh conditions.

    The next challenge for Lionel Lemonchois and his crew is none other than the Tea Route, a course covering nearly 15,000 miles between Hong Kong and London. Gitana 13 will attack this new record, held since 1990 by Philippe Monnet (single-handed in a multihull) in 67 days 10 hours and 26 minutes. The departure is scheduled over the course of the summer.
