  • 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.

    Leader of yesterday’s inshore races in Lisbon after the first day of racing, Edmond de Rothschild’s crew was able to handle the pressure on their shoulders today. Like in Valencia a week ago, Sébastien Josse dominated proceedings on the Tagus and pocketed the ten points awarded to the winner. It’s a result that has enabled the trimaran fitted out by Baron Benjamin de Rothschild to get back in touch with the leaders in the overall standing for the Route des Princes. Tomorrow, the fleet of MOD70s will leave the Portuguese capital and make for Dublin in Ireland. This second offshore leg, measuring some 990 miles in length, promises to be pretty muscly with a rather inhospitable Bay of Biscay.

    It’s not everyday that you see 70-foot trimarans powering across the waters of the Tagus at full pelt. To achieve this, there had to be perfect conditions: sunshine and a good breeze above all, despite it being very shifty in terms of strength and direction, enabled the Route des Princes’ fleet to really put on a show at the very heart of the Portuguese capital. Much appreciated for its beauty, the marine stadium certainly made things difficult for the crews and their tacticians in particular. Aboard Edmond de Rothschild, Sébastien Col really pulled out all the stops, positioning the trimaran fitted out by Baron Benjamin de Rothschild on the highest step of the podium. Modest as ever though, he put this latest win down to the excellent work of the crew as a whole: “Everyone did a great job, from the bowman to the grinders, to the trimmers and Sébastien of course at the helm. The quality of the manœuvres and the trimming is a great comfort for me as it enables me to make decisions late in the game, which means we can be very responsive. This pattern proved to be a strength in Lisbon on the atypical and rather random race zone. I feel very at ease alongside Sébastien Josse and the crew and I can’t wait to hook up with them again in Dublin.”

    Thanks to their performance today, the men of Gitana Team have bagged some precious points towards the overall ranking and are right back in contention. Whilst they had a six-point deficit in relation to Oman Air and were two points down in relation to Spindrift Racing on their arrival in Lisbon, Sébastien Josse and his crew are now just two points shy of the leader and tied on points with the one-design skippered by Yann Guichard.

    Back at the dock the skipper of Edmond de Rothschild was savouring his crew’s victory, but already his thoughts are offshore and the next leg, the start of which will kick off tomorrow: “It’s great to sail like that and win this second inshore. The group operates superbly well together and with Sébastien Col calling tactics, that’s a real bonus for the crew. The standard of the fleet is pretty similar and we saw today that prior to the final race there was still everything to play for. Naturally this latest victory is quite something, but the inshore discipline remains a very specific exercise. What we need now though is an offshore leg with us at the front of the pack so as we can gain the confidence we need. On the first leg we were in contention over the initial few hours of racing, but then we stuffed up a tricky section, which cost us very dearly. Here the objective is clearly to demonstrate that we’re just as at ease around the cans as offshore, as our crew is cut out for that.”

    Tomorrow at 1400 hours local time, Edmond de Rothschild and its adversaries will set sail for Dublin, which is the destination of the second offshore leg of the Route des Princes. The fleet will have to cover nearly 1,000 nautical miles before making for the emerald isle of Ireland. The race promises to be full-on with a deep depression in the Bay of Biscay, which will put the trimarans and the sailors under pressure: “It’s going to be quick! We’ll set off from Lisbon in the sunshine with around fifteen knots of breeze. However, towards the end of the evening we’ll switch to a reach and we’ll approach the centre of this famous depression, which is in the middle of the Bay of Biscay. On the first night, level with Cape Finisterre, we’re likely to have muscly conditions. We’ll round to the East of the depression and at that point the weather and the atmosphere will change aboard Edmond de Rothschild, with the arrival of clouds, rain and very heavy seas; a 5.5-metre swell will be the order of the day to the West of the depression. Once around this system, things won’t be any simpler as we’ll have to negotiate our approach towards the Fastnet with a NNW’ly wind and hence reaching conditions. Finally, the finish is set to be played out in downwind conditions, in what could be relatively light winds,” Sébastien Josse concludes.

    Change of crew for the offshore section

    Sailing aboard Edmond de Rothschild since the start in Valencia, Olivier Douillard will now be replaced by Antoine Koch on the offshore legs as planned. However, the trimmer will link-up with Sébastien Josse and his men again for the inshore races in Dublin and Plymouth: “It’s nice to leave the group on a victory, which reinforces the work that’s been done within Gitana Team over the past year and a half. The cohesion of the team really works well and you can see that in the inshore races, where you need to be very responsive. This is especially true when we sail very close to the cities, as was the case here in Lisbon. We had what it took to win these past two days of inshore races thanks to our consistent performance, which is very positive for the next stage. I’m stepping off the boat for the next leg, but I’m going to follow the team’s progress very closely in what promises to be a fast, muscly sprint at the start.”
