  • 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.

    Rounding Cabo Frio.

    Whilst the solo sailors in the Arkea Ultim Challenge – Brest began their sixth week of racing yesterday, Charles Caudrelier will shortly be crossing the trajectory he took nearly one month ago on his way down the Atlantic. Indeed, over the course of today, the skipper of the Maxi Edmond de Rothschild rounded Cabo Frio, located over 150 km to the east of Rio de Janeiro. Still beating in a medium wind, the leader of this round the world has been digging deep with a series of tacks over the past 48 hours to carve out a route forward in a rather atypical Atlantic. Overnight, he’ll finally point the bows of the five-arrow maxi-trimaran northward, where a long tack offshore of the Brazilian coast awaits.

    Since this morning, there are three boats navigating the Atlantic on the return leg. Thomas Coville treated himself to the 10th Horn of his career, rounding the legendary rock at the end of the world just over five days after the skipper of Gitana Team. Armel Le Cléac’h bid farewell to the Pacific some twenty-four hours beforehand, in the early hours of Sunday morning. Though this highly symbolic passage is often described as a moment of deliverance in a round the world under sail, one where you leave the isolation and the toughness of the Southern Ocean and return to a more familiar ocean, the climb up the Atlantic is certainly no walk in the park. A sentiment that the top trio in the Arkea Ultim Challenge are bound to echo.

    Over the past 48 hours, Charles Caudrelier has had to perform a sequence of around ten tacks. On top of that, his trajectory hugging the Brazilian coast has raised the stress levels and called for increased vigilance. Amidst the cargo ships, the fishing boats and scores of oil platforms, the AIS alarms have been frequently going off over the past few hours aboard the Maxi Edmond de Rothschild.

    Further south, Armel Le Cléac’h has also been forced onto a course hugging the land, glued to the shores of Argentina to let a powerful low-pressure system roll over, which formed on the peaks of the Andes and is now barrelling towards the Southern Ocean.  

    Benjamin Schwartz, weather router for the Maxi Edmond de Rothschild

    “It’s a fairly atypical and not terribly rapid climb up the Atlantic. We’re currently coming out of the acceleration created by Cabo Frio, the eastern tip of Rio de Janeiro. We’re going to tack in the coming hours to begin a long leg on starboard in an easing wind. There is very little gradient in the pressure to the west of the Saint Helena High, with a ridge of high pressure stretching as far as the Brazilian coast. It’s a very reliable trade wind situation with a zone of high pressure sprawling right out across the South Atlantic. Naturally, we’d have preferred to have had a boisterous trade wind and the kind of angle that usually enables us to crack the sheets a little and accelerate. Instead, we’ll have to hang onto a fairly tight angle as far as Recife and the north-east tip of Brazil. Our pursuers, between 1,800 and 2,000 miles behind, are in an entirely different weather system to us and will benefit from more favourable conditions. Over the coming days they’ll close on us and it will be important not to linger too long over the miles conceded.”
