  • 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 first encouraging steps for Edmond de Rothschild Group.

    After a few days of training punctuated by the breeze, the wind had eased this Tuesday, offshore of The Wave Muscat, providing a gentle start to the competition for the eight crews competing in the 2012 Extreme Sailing Series. Six races were able to be run during this opening day, three of which were won by the catamaran fitted out by Baron Benjamin de Rothschild. These results have enabled Pierre Pennec and his men to take the lead in the provisional standing. Though Edmond de Rothschild Group’s leading role doesn’t appear to have caused a stir among their adversaries, it is nonetheless satisfying for this crew, which has been largely revamped for this 2012 season.

    “This first day with the new crew has been very positive. The group is calm, professional and everyone has their little part to play, as much in their positions aboard as their general viewpoint, by conveying their vision of the race zone. Today we weren’t operating at the level we attained at the end of last season, which is completely normal. However, my initial feelings are very good. We’ve replaced two very good sailors with two sailors who are just as qualified and talented. I’m extremely pleased with the group and confident about the next stage in the competition”, explained Pierre Pennec, before highlighting the outstanding work of these crew members: “The race zone for today’s fleet racing was hard to read, as it was swept by a shifty wind, but the whole crew turned their experience to good account in deciphering it. Jean-Christophe made some very pertinent analyses and provided me with some very clear information, which paid off. The same was true of Bernard and Hervé, who helped me a great deal on this first day with a constant stream of information. Adeline also found her place within the group by perfectly blending into the crew.”

    A perfectionist as much as a competitor, the skipper of Edmond de Rothschild Group did however note a point which they will need to work on from tomorrow: “We were relatively safe, even set back a little at the starts, even though our three race wins partly bear out the fact that we did have some good starts. We’re going to have to look into that for the next stage.”

    Bernard Labro and Jean-Christophe Mourniac, respectively working the bow and the traveller, are the new recruits aboard Edmond de Rothschild Group. They give us their impressions on the opening day of their baptism of fire: “The integration within the crew of Edmond de Rothschild Group was very speedy. Our few days of training here, albeit just three, proved very beneficial. They enabled us to very quickly pinpoint a few minor errors, particularly in terms of communication, which enabled these imperfections to be erased before entering the competition. The work carried out on the boat by Gitana Team’s shore crew during the previous seasons is a real plus as can benefit from a very well prepared catamaran. For now, everyone is gradually finding their feet, but today’s results augur well for the future,” said a delighted “Kinou” (Jean-Christophe).For Bernard Labro, who’s getting to know both the new crew and the craft, the analysis was just as positive: “I cast myself into the same mould as the crew and things went like clockwork. My position as bowman is relatively physical, even though the conditions we had today enabled a relatively gently introduction to proceedings. We got in three days’ training with the whole group, which is a small amount, and we’re still having to make some adjustments, which is par for the course at the start of a collaboration. The communication lacks a bit of fluidity but it should be sorted relatively quickly.”

    Leaders in this evening’s provisional standing, the men in Edmond de Rothschild Group are ahead of Oman Air, even though the two teams are tied on points. Indeed, having won three races of the six run today, compared with just one win for the Omani team, Pierre Pennec and his crew have a slight edge. The English on GAC Pindar complete this top trio.

    As regards the weather, the wind eased throughout the day, with the ten knots measured early in the afternoon, dropping away to around six knots some three hours later, as it gradually shifted round to the right. This tendency for light conditions should be confirmed tomorrow. However, this evening it’s hard to have a clear view of the weather for the last two days of racing. Either the light airs will persist, or the influence of a low will provide some breeze, notably for the closing races on Friday. However, the major change on the cards tomorrow most certainly relates to the exercise. Indeed, after six races run outside The Wave Muscat port, the eight competing catamarans will move closer to both the shore and the Omani audience for the stadium races. These are synonymous with shorter courses, with an increasing amount of close contact, which will see a surge in the intensity of the races. “To be leading after six races is very good, but it’s not necessarily representative of the final outcome in this Grand Prix. We mustn’t get carried away. There are still three days of racing to go and tomorrow is the start of a new exercise for our crew”, recalled Bernard Labro, the new bowman.

    Rendez-vous tomorrow from 1400 hours (1000 UTC) to the track the progress of the eight crews in the stadium racing.
