  • 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 pause before the Horn.

    par Gitana

    Only 600 miles to Cape Horn, the “peak” of our southern trek, a 98° change in latitude from New York. Our trip south was fast up to the equator, and since then it has alternated between high and low phases, which is never good for the average. The same pattern held true over the past 24 hours, during which we had to settle for a score of only 336 miles. After a really rough night, our first foray into the 40s started out nice and calm. “We’ve just entered bird country,” said skipper Lionel Lemonchois. All around us, various varieties of petrels, including black ones, puffins and the first albatross, small ones, frolicked around Gitana 13 as we gradually lost speed. Crossing the high-pressure ridge was slower than expected and, surrounded by the incredible purity of majestic blue, we dropped the mainsail for a general inspection in the sun.
    Once we finished taking apart and checking the batten slides, we put the main back up amid a rising wind from the north quadrant, a sign that we’d arrived on the right side of the ridge. Thus began another sprint, flying the big and then small gennaker, with one or no reef in the mainsail. After a night of fantastic beauty, we were again busy in the “gym” before dawn Thursday morning with another gennaker switch, as the breeze began to soften, a harbinger of the next obstacle to come. To keep things interesting, this time we had to make our way around a small low-pressure system. In a few hours, the gennaker should be back in its bag, and we expect to continue nearly close-hauled toward the Le Maire Channel, which we hope to reach tomorrow, 1 February, during the day.
    Skipper Lemonchois gets the last word: “This route is thrilling, and like anything that’s thrilling, it’s not easy. We’re trying to do things as intelligently as possible, to be as responsive as possible, as we go from one weather system to the next. That requires a lot of work on the map table as well as on deck. But at least there’s no time to get bored.” The other nine of us can confirm these words! We haven’t had time to crack any of the books we brought onboard, and tomorrow we’ll be busy thinking about the Horn. So as for reading …
    Good night

    Bring in the Horn

    It’s sort of like two days before finals, but 35 years later. This is the reason I came: to round Cape Horn.
    I’m not really much more of a sailor—even after 17 years on multi-hulls, part-time trainer, part-time crew member—than I was a mountaineer after 12 years of teaching skiing in the Alps, or a pilot after several seasons of flying ultralights all over the country.
    I like to experience different human environments, but only for awhile, and then, after I’ve found my place, I leave a small imprint when I go. Yeah, so in two days I’ll make my mark: I’ll be a Cape Horner, like in the books. Will that be it then?
