  • 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.

    New start in Rio de Janeiro.

    Time goes by and every day is different in the Brest Atlantiques! Yesterday, at 19:00 UTC, following Tuesday’s pit stop in Salvador de Bahia and several long hours at a standstill along the beaches of Porto Seguro, Franck Cammas and Charles Caudrelier lamented a deficit of 466 miles in relation to the leader. However, 24 hours later, everything has changed. In this way, more than the first official course mark, Rio de Janeiro heralds a new start for the fleet of 32-metre giants. Indeed, after ten days of racing, the cards have been completely reshuffled and it is very much game on as they prepare to cross the South Atlantic bound for Cape Town in what is forecast to be a complex passage. At 15:00 UTC, the Maxi Edmond de Rothschild was back in 2nd place in the ranking some 135 miles behind the leader, Sodebo Ultim. However, the course adopted by the latter would suggest that the thrills and spills of this action-packed day are not over yet.
    From light airs to high speed, without any transition

    Yesterday, making her way along the Brazilian coast, the latest addition to the Gitana fleet broke the records for slowness… Posting an average speed of 2.6 knots over four hours, Charles Caudrelier and Franck Cammas had no other option than to just grin and bear it, whilst they traversed a windless zone left over by an ‘old’ front that was fading away. However, the rewards finally came at the end of the day with the return of a steadier breeze that became more established the further South the   Maxi Edmond de Rothschild got.

    «There we go! What joy…», gushed Charles Caudrelier with the arrival of the first gust, before reiterating his gratitude to the shore crew for all their work: «The stopover in Salvador cost us very dearly, as we’ve had a lot of light airs, but the boat is going extremely quickly once again, an average of 3 to 4 knots quicker than when the daggerboard was damaged. The team did a fantastic job.” This sense of satisfaction was widely shared by Franck Cammas: “We’ve rediscovered the sensations we felt prior to our breakage. Making a pit stop really was the right decision, even though it wasn’t an easy one to make. We lost a lot of miles but I’m hopeful we’ll quickly make them up.»

    One day later and a few miles further South, the wishes of the skipper of Edmond de Rothschild appear to have been fulfilled. 

    Bottleneck at the foot of the Corcovado

    As planned, Macif made a pit stop in the Marina Gloria in Rio de Janeiro to replace the rudder on her central hull, which broke after colliding with a UFO. It proved to be a long operation since they made the dock yesterday at 19:00 UTC and François Gabart and Gwénolé Gahinet then headed back out to sea today shortly before 15:00 UTC. At the front of the fleet, Sodebo Ultim made the most of this pit stop to snatch the lead and rounded the Cagarras Islands yesterday at 22:23 UTC. However, since then there’s been a dramatic turn of events since at midday, Thomas Coville announced that he was putting the race to one side temporarily for meteorological reasons and was retracing his steps towards Rio at the 15:00 UTC ranking. All this activity worked in the favour of the latest addition to the Gitana fleet, enabling our two skippers to get right back into the match once the Cagarras Islands were in the wake of their 32-metre giant. In fact, this official passage mark was immortalised in magnificent fashion by Yann Riou, the media man on the Maxi Edmond de Rothschild, thanks to his talents as a drone pilot extraordinaire.

    A demanding South Atlantic

    For several days, Marcel van Triest, like his fellow Maxi router ‘colleagues’, has been observing the classic pattern synonymous with the South Atlantic, namely a Saint Helena High positioned over the island that is its namesake and a downwind route to her South to make Cape Town, that didn’t look like a feasible option. Indeed, the high pressure is further South than usual and following the detection of ice by the CLS*, Race Management for the Brest Atlantiques has positioned an ice gate fairly far North, with its highest point at 38° South. This meteorological element combined with the safety element, and hence necessary, bars the way forward on the S’ly course, thus forcing the competitors to adopt a N’ly course, sailing fairly close to the wind, in order to reach the next course mark of Robben Island in South Africa. “We’re going to set off from Rio on a reach / upwind with the sheets eased a little, which is not a comfortable point of sail for either the sailors or the boat, as it puts a fair amount of pressure on the platform. At this time, the forecasts along the course we’re planning to take are announcing 3-metre waves and around thirty knots or so of breeze, which remains practicable. We’re remaining vigilant, primarily through Franck and Charles on-board, and of course through their router Marcel Van Triest, who’s scrutinising the situation with the utmost care”, admitted Cyril Dardashti, director of the five-arrow stable.
