  • 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 monohull in the colours of the LCF Rothschild Group left the port of La Trinité-sur-Mer on the afternoon of Tuesday 15th July – in order to take up her summer quarters. A six week refit awaits the men of Gitana Team in order to round off the preparation of the 60 footer prior to the long awaited Vendée Globe, on 9th November in Les Sables d’Olonne. This work will consist primarily of a honing process as opposed to any big changes.

    A summer break for some, intensive work for others… Gitana Eighty’s summer refit began a couple of days ago. Relieved of its spar, the monohull equipped by Baron Benjamin de Rothschild was placed onto a platform in the port of La Trinité-sur-Mer, prior to being put into one of the hangars at Gitana Team’s base in Saint Philibert. Over the next six weeks the upcoming programme is set to involve: a complete optimisation review, with the focus on improving the comfort of the solo sailor and hence the performance of his steed.

    Boat captain of Gitana Eighty, William Fabulet is the orchestrator behind this work. In permanent collaboration with Antoine Mermod, member of the Gitana Team design office, he coordinates the work, manages the schedule and ensures that all the different operations link together harmoniously: “Gitana Eighty has demonstrated her potential, and we’re not going to question what has worked well at the start of the season. There is a sizeable jobs list but essentially it comes down to optimising the existing boat and making her reliable” explained William as an introduction. 

    General inspection!

    After a busy start to the season in terms of sailing and prior to a round the world, it is perfectly understandable that one of the main objectives with this work is the complete overhaul of the vessel. “In order to guard against any wear or impact not visible to the naked eye, a meticulous inspection of the sensitive zones was performed the minute Gitana Eighty entered the hangar. Following on from that there will be a lot of work involved in the dismantling, since the boat’s platform will be stripped right down. Once it has been dismantled, the winches, blocks and other elements of deck hardware will be carefully cleaned prior to being put back in their original place at the end of the job. This section in particular will be the responsibility of Sébastien Thétiot, as will the mechanical and hydraulic overhaul. For his part, Yann Le Govic, our in-house customised splicing expert, has already worked on the running rigging, as the majority of the warps will be replaced in line with a systematic precautionary process. Benoît Piquemal will concentrate on the reliability of the automatic pilot and communications systems.
    Finally, a team of five people specialised in composite material will set to work on the structural elements, with the aim in particular of optimising the ergonomics. There will be an emphasis on the evacuation of water from the cockpit for example, in order to make it safe and more pleasant, particularly in the Deep South”
    concluded the boat captain.

    A relaunch early September

    Entrusting the summer work to the expert hands of his shore crew, Loïck Peyron can thus grant himself some well earned rest after covering over 8,500 miles since the start of the season 2008. For a month and half, the shore crew won’t be sparing any effort to ensure the scheduled relaunch at the start of September. Two months from the big start in Les Sables d’Olonne, the countdown to the Vendée Globe can now begin.

    Qualification secured

    Following the change of keel on his return from the United States, the skipper of Gitana Eighty had to perform a technical validation session of 1,500 miles to qualify this new appendage. Loïck Peyron has thus profited from the last few days of joint training with Jean-Pierre Dick – we recall that the 60 footer belonging to the Nice skipper is the sistership to Gitana Eighty – to complete this formality. Setting off from La Trinité-sur-Mer, the two men headed out towards the Fastnet – on the SE tip of Ireland – prior to dropping back down into the Bay of Biscay towards La Coruña. It is at the latitude of Bordeaux that Baron Benjamin de Rothschild’s monohull got back on course for her home port. It was a satisfactory validation course, which will notably have enabled the sailor from La Baule to test his steed in some steady breeze.

    Having now fulfilled all the formalities required by the organiser of the Vendée Globe, Gitana Eighty secures his qualification for the major event of the Imoca 2008 circuit; the first planetary adventure for a monohull in the colours of the LCF Rothschild Group.
