  • 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.

    This Sunday at 12:30 UTC will mark a fortnight at sea for Charles Caudrelier in the Arkea Ultim Challenge. Since passing the Agulhas Cape at the tip of South Africa on Friday afternoon, the firm leader of the round the world ULTIM race has been navigating the Indian Ocean and he is not hanging around. Managing to slip ahead of a depression four days ago in the South Atlantic, the Gitana Team sailor has been racking up over 800-mile days and, over the course of today, he’ll pass the symbolic barrier of 10,000 miles covered over the ground since the start in Brest on 7 January. Last Wednesday night through into Thursday, the skipper of the Maxi Edmond de Rothschild even came close to posting a new record time for the greatest distance covered in 24 hours: 842 miles posted compared with the reference 850, which François Gabart clocked up in 2017. However, these figures are of no concern to Charles Caudrelier as he admitted yesterday in his latest videos from the ocean. Instead, the skipper is totally dedicated to being completely at one with his fantastic flying machine and getting her making headway.
    Sunday jaunt offshore of the French Southern and Antarctic Lands

    The Arkea Ultim Challenge is the first single-handed round the world race for ULTIMs, yet first and foremost it is an adventure. An extraordinary maritime challenge, it is leading a set of committed men towards extreme and remote latitudes where few sailors can pride themselves on one day venturing into. This Sunday morning, Charles Caudrelier passed the Crozet Islands, the first archipelago of the French Southern and Antarctic Lands (TAAF), which are made up of five administrative districts: the Crozet archipelago, the Kerguelen Islands, Saint Paul and Amsterdam, Adélie Land and the Eparses Islands. This is not the first circumnavigation of the globe for the skipper of the Maxi Edmond de Rothschild (three to his credit in the Volvo Ocean Race), but it is the first time he has been racing in these waters single-handed and on a multihull.

    To each their weather scenario

    Last night, Thomas Coville joined Charles Caudrelier navigating the waters of the Indian Ocean. At midday, Sodebo Ultim 3 was lying some 1,276 miles astern of the Maxi Edmond de Rothschild, whilst the Maxi Banque Populaire XI and Actual Ultim 3 were still caught in the clutches of the Saint Helena High lamenting a deficit of over 2,700 miles.
    This massive separation comes largely as a result of the weather. By managing to hitch a ride on the string of depressions rolling in from the Deep South and keeping ahead of the front associated with one of them, Charles Caudrelier was ideally placed to lengthen his stride for four days on a long tack to the south-east. This long ‘straight’ course and the days spent making high speed have enabled him to really extend away from his pursuers, who are in another weather system altogether now. Since yesterday, manoeuvres have been par for the course again on the deck of the Maxi Edmond de Rothschild. Indeed, the five-arrow giant is close to the Antarctic Exclusion Zone managing to strike the right balance between wind strength and sea state. This famous AEZ mapped out and governed by Race Management for the Arkea Ultim Challenge, takes the form of a virtual line, which the competitors are forbidden from crossing if they are to avoid a penalty.
