  • 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.

    Spectacular sailing.

    After last night's violent storms, a strong north-north-easterly wind soon cleared the skies. Hot weather has made a comeback bringing perfect albeit windy conditions. The 10 entrants in the Grand Prix de Corse are back in business once again.

    After last night’s violent storms, a strong north-north-easterly wind soon cleared the skies. Hot weather has made a comeback bringing perfect albeit windy conditions. The 10 entrants in the Grand Prix de Corse are back in business once again.

    As soon as the fleet left the harbour, they were greeted with choppy to strong seas, with winds gusting to 25 knots giving the Race Committee plenty of work to keep them busy – on several occasions they had to check the race marks were safely moored.

    Round n°2 of the Grand Prix de Corse

    At 11h 14, the 10 strong fleet set out head to wind at 18 knots on the first windward / leeward loop, the second round in this Grand Prix. Wind strength ( 15/20 knots with gusts of up to 25 knots ) made several tactical options possible, explaining the several upsets in this round which lasted a little over one and a half hours. The early stages of the race saw Gitana 11 in the middle of the fleet and gradually making her way up through her opponents to 4th. Shortly before crossing the line, Groupama II had to lighten up her pace a little when the crew saw that a shroud chainplate looked as though it were about to part company with its float, running the risk of having the mast come tumbling down. No sooner had Franck Cammas brought his green trimaran across the start line than he turned tail heading back to Calvi harbour for emergency repairs putting him out of action on the next race.

    Round n°3

    Two incidents marked the start of this round. One was not too significant, but the other turned out to have major consequences for two competitors. In the first instance, Gitana 11 and Sergio Tacchini, no doubt carried away by their desire to get down to it, crossed the line too early and lost a number of precious minutes in having to cross the line once again. In the second instance, the lively start cost Sodebo and the Italian boat, Tim, very dearly indeed as they collided violently into one another. The force of the impact was such that the Sodebo lost the crash box of her port float and Tim waved goodbye to more than one metre of her aft starboard float, the flank also sustaining damage in the impact. It was not long before both boats were keeping Groupama II company in Calvi marina to start repairing the damage sustained in the collision. Both parties involved lodged the usual protests. For all that Gitana 11 was hampered by her premature start, she was 5th to round the first mark just one minute behind Banque Covéfi. The crew of Gitana 11 was clearly on the ball in the second half of the season. She continued to snap away at the heels of the leading pack right through to the final stretch of this round, finally coming away with a brilliant 2nd place.

    Round n°4

    After having made provisional repairs, Groupama II got back into the thick of it, leaving the rather unfortunate colleagues Sodébo and Tim up to their eyes in laminate repairs. At 16h 30, the Race Committee kicked off a third start …. which almost all of the boats made too hastily. General recall, everybody back and the race finally started 15 minutes later in conditions where the sea was still rough and the sun was still shining brightly, but where the wind was starting to drop. In this last race, Gitana 11 made a speedy climb up through the ranks after a minor incident at the first mark. Fred Le Peutrec’s crew, going for it all the way, came into contact with the mark earning a 360° penalty turn into the bargain. Not the sort of guys to let this get them down, the Gitana Team fought twice as hard as soon made up for lost time, after one and a half hours racing taking third behind Groupama II and Sergio Tacchini. These are Gitana 11’s fiercest rivals on the circuit. At the end of this truly amazing day, Gitana 11 and Groupama II were on a level pegging for second, but yet again, Groupama took the advantage as she had win three rounds. This makes Gitana 11 3rd in the overall rankings, after 4 rounds already run in this Grand Prix de Corse whcih will be finishing tomorrow with what everyone hopes to be yet another extraordinary day of racing.
