  • 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.

    Bye Bye Plymouth!.

    A low pressure front, synonymous with deteriorating conditions punctuated by a change of wind direction and speed as well as rain, was set to roll across the start zone for the Transat bakerly this Monday.

    A low pressure front, synonymous with deteriorating conditions punctuated by a change of wind direction and speed as well as rain, was set to roll across the start zone for the Transat bakerly this Monday. These forecasts played out to perfection on the water with the sky and the sea merging into a very English grey monochrome when, at 14:30 GMT+1 on the dot, the 25 solo sailors set sail for New York. The atmosphere was also pretty lively off the breakwater, which protects Plymouth Sound, with a WNW’ly wind of around fifteen knots or so and a big but manageable swell. At the helm of the Mono60 Edmond de Rothschild, Sébastien Josse managed to skilfully position himself on the line for a careful start in the leading group.

    Whether you’re driving a boat with one or several hulls, regardless of the potential horsepower under the ‘bonnet’, casting off to set sail alone across the Atlantic is never easy. Sébastien Josse has made competition his profession and experience obviously helps in these personal moments where concentration and emotion both take centre stage. The skipper of Gitana Team is well aware of the strengths of the Mono60 Edmond de Rothschild as well as the unknowns he hopes to discover over the course of the very demanding 3,000-mile crossing. For now, the weather forecasts are still raising some questions, but the major options are set to quickly be revealed. Indeed, from tonight we’re likely to get a more accurate idea of the intentions of the various skippers: will we see the fleet spread out, with one part favouring the north and the other the south, or will we see, in contrast, a bunching of the fleet? 

    Quietly confident and happy to be tackling his 2016 sporting season with this legendary transatlantic race, Sébastien Josse shared his thoughts with us shortly before he climbed aboard the most recent of the Gitana fleet: “After analysing the latest grib files, there still appears to be two weather trends: a northerly course, with a very boisterous passage in a low at 50 degrees north, and a second trajectory, a little further south, which is fairly uncharacteristic of The Transat. Indeed, the latter would take us via the Bay of Biscay, Cape Finisterre (NW tip of Spain) and near the Azores, before linking onto a course due west towards the iceberg exclusion zone off Newfoundland. It’s a very quick downwind trajectory, since we could be at Finisterre by tomorrow evening… To the north, it’s a very different ball game with upwind conditions towards the Isles of Scilly and average speeds of around 10 knots involving a series of tacks, but that too is a shorter course. As such, we need to weigh up the pros and cons… However, from tonight or tomorrow morning at the latest, the skippers are likely to have revealed their hands. Aside from that, I feel good. I know that we haven’t managed to rack up many hours of sailing on the boat this year yet, so I’m setting sail with what I already know and the idea is that I’ll get my bearings first of all and then gradually pick up the pace. However things pan out, as ever, it’s the weather that will dictate a great many things…”
