  • 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.

    Tactical and demanding, the race zone in Amsterdam lived up to its reputation on this first day of racing. Given the capricious, light breeze the organisers were able to run eight races this Friday. Racking up two wins and putting in a very consistent performance throughout the afternoon, the men aboard Gitana Extreme – LCF Rothschild Group are lying in ambush just two points behind Oman Renaissance, the provisional leader. However, as everyone on the water could testify today, the team are going to have to battle it out all the way to the finish given the very slight separation between those in the top spots and those at the bottom of the table.
    All smiles on his return to shore, Yann Guichard is a skipper who is happy with the performance achieved by his crew: “It’s a very satisfying first day. We sailed well despite the difficult conditions. There was a lot of contact with damaged boats but for our part we didn’t incur any penalties, which is really positive. All in all we got off to some good starts, except for in the last race where we crossed the line 50 centimetres too early! Whatever happens, despite overshooting the start, our positioning was spot on” explained the Breton sailor. “The first days have never been our forte so to finish 2nd this evening, just two points behind Oman Renaissance is motivating for the next stage. We’re going to have to dig our heels in over the next two days as I think the Amsterdam grand prix may be the turning point in this 2009 championship.”
     
    A hard race zone to read
    800 metres long by 200 wide, not to mention the canal boats moored alongside the quays, such is the setting when competing on this Dutch race zone. As such it is narrow as well as being flanked by numerous buildings. With such a playing field on offer to the Extreme 40s for this 5th stage of the circuit, even the best racers would be wise to be careful. Indeed the eight races run this Friday were certainly not something for the skipper of Gitana Extreme – LCF Rothschild Group and his rivals to sniff at: “The race zone is difficult on the one hand because it’s small and there are nine boats competing on it, and secondly the wind has never been stable either in terms of direction or intensity. We had between 4 and 10 knots of breeze through the day, but there were some little gusts which you couldn’t afford to miss and make the best of” explained Yann Guichard.
     
    Tomorrow the wind isn’t likely to be as steady and if these forecasts prove right, racing may be even spicier than it already is. With this in prospect, Yann Guichard had this to say: “The battle is likely to be even more complicated tomorrow but you have to take things race by race and above all, never give up!”
     
    Damage aboard Oman Sail Masirah
    The leader of the championship – Oman Sail Masirah – has had a dark day. After some mixed results in the first three races, Pete Cumming’s men were involved in a collision with the Extreme 40 BT.  The classic port starboard incident due to a mistake by BT has had serious consequences since the hole made in the port hull after this violent impact forced the Oman team to make straight for the quayside. Masirah was lifted out of the water into the crowd to enable the shore crew to proceed with the necessary repairs: the composite work is set to last all night in order that the one design can continue racing at the start of tomorrow afternoon. As regards the ranking, given that they are not responsible for this unfortunate incident, Pete Cumming’s crew should be compensated for the five races they were unable to compete in today. However, suffice to say it’s a big setback for these men who will have their work cut out getting back in contact with the leaders.
