  • 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 Maxi Edmond de Rothschild takes the win in the Drheam Cup.

    What a pleasure to rekindle the ties with the intensity of competition! The beaming smiles of the six sailors aboard the Maxi Edmond de Rothschild said it all this Tuesday lunch time after crossing the finish line of the Drheam Cup 2020 offshore of La Trinité-sur-Mer in south-west Brittany. And to add to the magic of the moment, it was in full flight making over 35 knots that the 32-metre giant rounded off the 750-mile course that began at noon on Sunday in Cherbourg. What a show! The Cammas-Caudrelier duo and their men took victory after 1 day 21 hours 30 minutes and 33 seconds, two hours ahead of 2nd placed Sodebo, Actual completing the podium. It was a hotly contested and thrilling match between these three crews thanks to some very varied conditions, ranging from 1 to 22 knots of breeze! With a firm hold on the head of the fleet from the start despite the light winds, the sailors of Gitana Team hung onto the top spot throughout the 750-mile course. Last night, they made the most of a long and particularly dynamic reach to definitively open up their lead to take line honours shortly after 10:30 hours local time this Tuesday 21 July.

    Masterful sailing from beginning to end

    “Right at the start, we pulled off a small tactical move inshore, which enabled us to steal a bit of a march on our rivals even before we attacked the cross-Channel passage. Up next, the weather didn’t necessarily favour the lead boat, which meant that our pursuers were able to catch us right up again, but this little cushion of a lead we’d gained at the start, small though it was, was important as it meant we always had a slight jump on them throughout the race! That slight edge also prompted our rivals to make errors by taking greater risks to close on us, especially as we negotiated a ridge of high pressure and again last night”, explained Franck Cammas.

    Initially, the Ultimes were due to round the Isle of Man in the Irish Sea as part of a 1,100-mile course. Twenty-four hours before the start and taking into account the latest grib files, Race Management, in agreement with the organiser, opted to shorten the course to prevent the fleet from being ensnared for days in the calm conditions associated with the high pressure. The passage of a waypoint in the Irish Sea yesterday served as a good indicator of what would have awaited the crews in this race without this modification: “It was a very wise decision to shorten the course and bring it in line with the weather conditions at the time. The aim was to sail and not remain pinned to the racetrack for hours in windless zones and hence with no match racing,” explained Cyril Dardashti, director of the Gitana Team. Franck Cammas shares this sentiment, admitting on his arrival dockside today how much he’d enjoyed the past two days of racing: “It was a very fine race and it was intense, which is just the way we like it. There were some tactical phases, other periods which were just a drag race and a lot of reaching at the end, as was the case during the second night when we were hunting down the cardinal mark off Rochebonne, which was great because we didn’t have conditions as quick as that in last year’s Fastnet. It was quite good being able to push the boat in these conditions. It’s never easy to permanently remain close to 40 knots, like we did last night. It was a great finish. We learnt a great deal from this race. It was a technical course in a small space, because the English Channel and the Irish Sea aren’t very big at the end of the day given the size of our boats. That means we can run through all the different manoeuvres you can do on an Ultime.”

     

    A shakedown for the crew prior to the Jules Verne

    The only race on the cards for the 2020 season before their Jules Verne Trophy record attempt, the Drheam Cup was a must and the perfect opportunity for the men of the Maxi Edmond de Rothschild to see where they’re at both competitively and technically, as Charles Caudrelier explains:“It was important to be here as you can count the number of opportunities to go racing on the fingers of one hand! This is especially true in conditions like those we encountered last night, which enable us to drive the boat at her full potential. We’re delighted with the modifications we made to the Maxi over the course of the winter. From the outside, the boat looks the same, because aside from the fairly obvious aerodynamic additions, like on the beams, you really need sharp eyes. However, the team has done a really good refit and today we are able to see the fruits of our labour. I believe we have further optimised the platform and the level of performance we’ve achieved since her relaunch has made it all worthwhile. The race format didn’t necessarily lend itself to actually training for the Jules Verne, but it gave us a chance to head offshore again and rediscover the mechanics of sailing the boat… The  Drheam Cup has launched our Jules Verne Trophy record campaign!”

    Following on from the Fastnet, in August 2019, and the Brest Atlantiques last December, Franck Cammas and Charles Caudrelier have secured another win in the Drheam Cup. That brings to three the number of victories out of the four races contested since their arrival in the Gitana Team, figures which testify to the great alchemy that reigns between the skipper pairing and the latest addition to the Gitana fleet. Three years on from her launch, the five-arrow maxi-trimaran, the first vessel of her kind designed to fly in the open ocean, has unquestionably entered the maturity stage, but according to her skippers, she still has some surprises in store and has even more power under her bonnet: “We beat the boat’s speed figures last night, posting over 46 knots. However, what’s most impressive of all are the average speeds in excess of 40 knots as we’re now able to keep up this pace for long periods. It’s not over yet!” concluded Charles Caudrelier, grinning from ear to ear.
