  • 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 rhythm of the European Tour is steady and only allows the sailors a short amount of down time. After two days of City Races, including a particularly animated one yesterday in a fine breeze of around twenty knots, the five competing crew headed back offshore today bound for Cascais, Portugal. It was at 1400 UTC that the fleet of trimarans powered off under overcast skies in a 15-18 knot SSW’ly wind. The authors of a very good start, Sébastien Josse and his five crew concluded the three-mile coastal course around Dublin Bay at the front of the pack, thus racking up a three-point bonus for this performance.

    Declarations from the crew before leaving the port of Dùn Laoghaire

    Sébastien Josse, skipper of Edmond de Rothschild Group: “We’re very focused as we know that this first night at sea will be both intense and important. The first tricky stage will be at the Fastnet, where we’ll have to negotiate our way through a front. Tonight we should have 25 to 30 knots of breeze and a 2.5m swell, so we’ll have to keep an eye on the gear and the guys. During the start of the course, the idea is to find the right compromise between attacking, resting and positioning ourselves for the next stage. However, we’re already aware that the first few hours won’t be at all restful!”

    Antoine Koch, in charge of the navigation and strategy in the offshore races: “The overall strategy and the way the weather phenomena link together hasn’t altered since yesterday. However, we still have a few uncertainties and we’re going to have to watch the way certain systems evolve and adjust our course as we go along. Initially this relates to the timing of the passage of a front level with the Fastnet. We don’t yet know if the latter will roll through before or after us at the South-West tip of Ireland and what wind we’ll be left with at the back of this system. The second critical point, which will influence our trajectory offshore of the Bay of Biscay, is whether or not there will be a zone of transition without wind as we make landfall on the Portuguese coast. In the first leg, we pretty much stuck to the planned course, despite the fact that the race lasted 3 days and 12 hours. That would suggest that the forecasts were very accurate. Here the situation is more complicated.”

    We get it. The theoretical 1,215 miles, which make up the second leg between Dùn Laoghaire and Cascais are likely to be action-packed, with at least two key transitions. This complexity is heightened by the fact that a final decision hasn’t yet been made as regards the last few miles of the race along the shores of Portugal. Basically, depending on when the MOD 70 fleet arrive offshore of Cascais, Race Management reserves the right to shorten the course or otherwise. However, for the time being, the MOD Edmond de Rothschild Group and its rivals will initially have to make towards Caiscais and then set a course to the South towards the Lagos mark, situated 17 miles off Cape St-Vincent, before heading back the way they came to conclude the race. This final section of the race could well reshuffle the cards and upset the hierarchy established offshore. Whatever the final scenario chosen, the men of Gitana Team and their rivals are expected into Portugal on Wednesday.

    Order of passage at the final windward mark of the coastal course
    1. 1. Edmond de Rothschild Group – 3 points *
    2. Spindrift Racing – 2 points *
    3. Race for Water – 1 point
    4. Musandam – Oman Sail
    5. Foncia

    Standing in the European Tour (before leg 2 from Dublin – Cascais)
    1. Foncia – 12 + 50 + 3 *+ 10 = 75 points
    2. Spindrift Racing – 11 + 46 + 1*+ 12 = 70 points
    3. 3. Edmond de Rothschild Group – 10 + 42 + 2*+ 11 = 65 points
    4. Race for Water – 8 + 38 + 9 = 55 points
    5. Musandam – Oman Sail – 9 + 34 + 8 = 51 points

    * corresponds with the points’ bonus awarded to the top three boats at the end of the coastal section contested in Kiel on 2 September and in Dun Laoghaire on 9 September.
