  • 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.

    Arrival tonight for Sébastien Josse and Edmond de Rothschild.

    At the 1000 GMT position report this Monday 10 November, Sébastien Josse was still lying in third place some 250 miles from Pointe-à-Pitre, 250 miles from completing his first solo transatlantic aboard a multihull. For his final night at sea in the Route du Rhum Destination Guadeloupe, the skipper of the Multi70 Edmond de Rothschild has spared no effort in maintaining his lead over his rivals; efforts which appear to be paying off since Oman Sail is in fourth position, 82.3 miles astern whilst Prince de Bretagne has racked up a 103-mile deficit. According to the latest estimates by his routers Jean-Yves Bernot and Antoine Koch the trimaran fitted out by Baron Benjamin de Rothschild is likely to make the northern end of the island midway through tonight (early evening local time) and round off this 10th Route du Rhum a few hours later after negotiating the 60-mile looped circuit around Guadeloupe, a final hurdle which is sure to spice up the end of the race.
    New record

    For some hours, the Route du Rhum – Destination Guadeloupe, in its 2014 guise, has known its winner. Loïck Peyron succeeds Franck Cammas on the list of winners of the event. Added to that, by crossing the finish line this Monday 10 November shortly after 0400 GMT, the skipper of Banque Populaire VII has stamped his mark on the event and beaten the reference time, which has been held by Gitana Team since  2006, by over two hours. Leading the fleet since the first night at sea and the passage around Ushant, the sailor from La Baule on France’s Atlantic coast held firmly to pole position throughout the 7-day race. In so doing he has secured a stunning victory, which is saluted by the whole of Gitana Team.

    Gunning for the podium

    Out at sea, the battle that is being played out less than 300 miles from the finish remains intense and thrilling. Indeed, since late morning yesterday, the hierarchy of recent days has been rejigged and the race for the podium is on. The skipper of Edmond de Rothschild has moved up into the provisional third place to the detriment of Lionel Lemonchois, who has since been relegated to fifth position. By gybing prior to his adversary and creating separation to the south, Sébastien Josse was able to sidestep the lines of squalls, which have cost the skipper of Prince de Bretagne so dearly. Following this episode, the solo sailor and his routing cell didn’t think twice about continuing the push southwards towards the Antilles arc last night to ensure a better angle of approach to butterfly island: “Yesterday, we decided to continue on the attack rather than covering Sidney Gavignet and matching him gybe for gybe and this morning the situation is pretty satisfactory. Not only has Sébastien sailed very well once again, his position enabling him to extend away from his pursuers slightly, but he has most likely enjoyed a more comfortable tack than them with fewer squalls and instability and that’s what we were looking to achieve. In all probability, today will involve a long starboard tack towards Guadeloupe, but we’ll have to deal with some slight oscillations in the wind and we may need to reposition ourselves if the wind shifts are significant,” explained Antoine Koch.  

    Tackling the circumnavigation of Guadeloupe

    The rule is the same for everyone; as stipulated in the Sailing Instructions, those competing in the Route du Rhum – Destination Guadeloupe will have to round the island by leaving it to port and then head for the finish line set just a stone’s throw from Pointe-à-Pitre’s harbour basin. In this way, Sébastien Josse is set to round the islet of Tête à l’Anglais, situated to the north of Basse Terre, by leaving it to port, at which point he’ll hunt down the Basse Terre mark, which he needs to leave to starboard and then head into the Canal des Saintes to make the finish. This 60-mile course may prove to be particularly hazardous downwind of the island, especially at night, as the router explains: “this circumnavigation represents the final obstacle on this course and one not to be sniffed at. La Soufrière culminates at 1,467 metres and generates a very sizeable wind shadow, which varies a great deal according to the time of day. It’s a particularly tricky section at night, as the winds are often very light and very changeable…”

    From their ‘centre of operations’ in La Rochelle, Jean-Yves Bernot and Antoine Koch naturally monitored the end of Loïck Peyron’s course in great detail so as to substantiate their observations and prepare as best as possible for the passage of the Multi70 Edmond de Rothschild: “With an ETA at Tête à l’Anglais at 1200 midnight (GMT) tonight, Sébastien has every chance of experiencing similar conditions to those encountered by Loïck, namely a fairly light section to leeward of the island level with La Soufrière. Indeed, as expected, Loïck really stalled for about ten miles between the volcano and the Basse-Terre mark. Clearly this is the most complicated section to negotiate”, concluded Antoine Koch.

    On reading these few lines, we can easily grasp why this conclusion to the race is something that is dreaded by solo sailors. Sébastien Josse will have to keep calm, even if he sees his pursuers closing on the Multi70 Edmond de Rothschild. In this regard though, the skipper of Gitana Team has demonstrated for the past 7 days that he has nerves of steel!
