  • 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.

    Onward to Amsterdam.

    The fourth grand prix of the season came to an end in Germany this Sunday with a 4th place for the men on Gitana Extreme – LCF Rothschild Group. Decidedly performing very well this season, Pete Cumming’s men scored another win for the 3rd consecutive event, even though ultimately there was precious little between them and their compatriots.

    The fourth grand prix of the season came to an end in Germany this Sunday with a 4th place for the men on Gitana Extreme – LCF Rothschild Group. Decidedly performing very well this season, Pete Cumming’s men scored another win for the 3rd consecutive event, even though ultimately there was precious little between them and their compatriots.
    This lunchtime, as the ten Extreme 40 crews calmly climbed aboard their steeds, the competition was more open than ever given the very slight separation between the top four one designs, which augured well for some high tension racing. Indeed the false start by Gitana Extreme in the first race was a perfect illustration of this. However, Yann Guichard had warned of this at the start of the grand prix: “you have to be an opportunist and know how to take risks if you’re playing to win!”
     
    The stormy downpours once again livened up this third and final afternoon of confrontations. Between the squalls and the comings and goings of the ferries, which leave Kiel in their wake as they head into the Baltic Sea, the race committee managed to launch six fine races today. However, there were mixed results for the catamaran equipped by Baron Benjamin de Rothschild: “Our first three bad races of the day put paid to our chances of a podium finish in this fourth stage of the circuit. The reasons for this were that, despite a good final race, in which we came second, we weren’t able to come back on Groupama 40” explained Yann Guichard. “However, one positive point that I’d like to highlight, is how the crew handled these tricky moments. Indeed, even though we finished at the back of the leading pack in half the races, everyone remained concentrated to get back into the action!”
     
    Applauding the performance of the three crews in front of him on the podium, the skipper of Gitana Extreme was keen to, quite rightly, pass harsh judgement on the problems encountered once again by the jury presiding over the race zone: “The umpires weren’t up to scratch with events and I’m very disappointed. We had three big errors committed on us which weren’t penalised and these have cost us dearly in the final ranking. However, we aren’t the only crew in this situation. Since the grand prix in Hyères, we have been pointing the finger at the lack of referees on the water…”
     
    In the championship ranking, this German meeting hasn’t been a very good operation for the Gitana Team. However, though they’ve lost ground on the men from Oman Sail Renaissance, Yann Guichard and his crew – made up of Pierre Pennec, Christophe Lassegue and Hervé Cunningham – are hanging onto their second place, just four points behind the leader Oman Sail Masirah.
     
    The 5th event of the championship will take place from 25th to 27th September 2009 in the charming Dutch city of Amsterdam. In the meantime however the Gitana Team will be back in Brittany for the launch of the revamped Gitana 11. In fact, in a few days time, the victorious trimaran from the Route du Rhum 2006, will return to her natural element, where her new lines will be revealed.
     
    To conclude, a hearty congratulations to the crew of Ecover who were back on the water this Sunday! Victim of a capsize on Friday, Mike Golding’s troops weren’t sparing of their efforts as they readily took part in today’s racing.
