  • 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 North Pacific in 11 days 12 minutes 55 seconds.

    And number two! Gitana 13 adds the North Pacific crossing to its list of conquests by covering the 4,482 theoretical miles of the (direct) course in 11 days 12 minutes and 55 seconds. Leaving San Francisco on Saturday 29th March at 22h45'45''UT, for the second record of their 2008 campaign, Lionel Lemonchois and his ten crew crossed the finish line…

    And number two! Gitana 13 adds the North Pacific crossing to its list of conquests by covering the 4,482 theoretical miles of the (direct) course in 11 days 12 minutes and 55 seconds. Leaving San Francisco on Saturday 29th March at 22h45’45”UT, for the second record of their 2008 campaign, Lionel Lemonchois and his ten crew crossed the finish line off Yokohama, in Tokyo Bay on Wednesday 9th April at 22h58’40” UT. The maxi-catamaran equipped by Baron Benjamin de Rothschild improved on the previous reference time by 3 days 22 hours 27 minutes 46 seconds, held by Olivier de Kersauson and his crew on Geronimo since 2006.
    The inappropriately named ‘Pacific’

    Sylvain Mondon, Gitana 13’s router, announced it even before the maxi-catamaran had even slid its bows under the Golden Gate Bridge: “This Ocean is anything but Pacific!” Lionel Lemonchois and his men were able to verify that the Pacific Ocean was far from peaceful as their router had indicated. By choosing to adopt a central route, in order not to extend the course, the sailors of Gitana Team knew that the weather conditions wouldn’t be at all relaxing. However, such was the cost of swiping this record from the maxi-trimaran Geronimo. Between passages of fronts, rounding the high pressure zones – three in total-, managing the transitions and the negotiating of a storm, the crew of Gitana 13 knew how to pull out all the stops and track a route towards Yokohama. A tricky exercise, in which they counted on Sylvain Mondon (Météo France), a real twelfth man from his offices in Toulouse.

    The record figures

    Gitana 13 covered the 4,482 theoretical miles of this crossing at an average speed of 16.96 knots. However, in practice, the maxi-catamaran in the colours of the LCF Rothschild Group, had to cover over 5,616 miles, at an average speed of 21.26 knots, to make Japan. Explanation: on this record the direct route would force the sailors attacking the record to adopt a very northerly trajectory to make Yokohama. In reality, the weather conditions dictate a much more southerly course then the ideal track.

    With a peak speed of 39.7 knots, performed by the skipper of Gitana 13, it’s a new personal record for the crew on this crossing. The best day recorded by Gitana 13 in terms of distance covered over the water in 24 hours is that of 3rd April with over 612 miles on the counter. Finally, in terms of a lead, Gitana 13 racked up a 612 mile credit over Olivier de Kersauson and his men.

    Interview with Lionel Lemonchois, skipper of Gitana 13

    11 days 12 minutes 55 seconds, what do you think of your new time?
    “It’s a great time and we’re really happy. Given the weather conditions before we set out, I told myself that if we did it in 12 days it would be a good performance already. And, to look at our average speed over the actual distance covered is very honourable.” 

    This crossing wasn’t at all restful, could you outline the conditions you’ve been encountering during these 11 days at sea?
    “We’re certainly very tired at the end, as the past eleven days at sea have been intense. The Pacific offers some rapid and numerous weather sequences. In total we encountered two lows, including a very strong one at the approach to the Japanese coast, then three high pressure zones to round and as many transition zones to negotiate. Prior to our departure, the second part of our course was still very uncertain but everything fell nicely into place in the end. The storm over the past few days gave us a good boost on our journey to Japan. This period, though stressful, will remain a highlight of our time at sea. We had strong winds gusting to over 60 knots but it was the waves above all else which were impressive, rising to over 10 metres in cross seas. It was quite a spectacle!”

    How did Gitana 13 handle in these feisty sea and wind conditions?
    “Gitana 13 is a very sound boat. It only buried its bows once or twice in the storm, other than that it was never lacking. The modifications made by Gitana Team when she was taken over in 2006, particularly the raising of the forward beam, clearly improve the boat’s behaviour and the safety of the crew. Despite the sea state we encountered – and yesterday morning’s conditions weren’t insignificant – the boat’s perfect. We didn’t break a thing.”

    You worked with Sylvain Mondon on shore for the weather part of this record attempt, the pair of you still appear to work as well together as ever?
    “Sylvain was perfect as usual! He is always there, full of finesse in his analysis and concise… it suits me down to the ground. We don’t necessarily have a great deal of vocal exchanges, other than in the storm over the past few days, but he always sends us very precise information. You can tell that he loves what he does and it’s always a pleasure to work with him.”

    What is your programme and that of the maxi-catamaran over the coming weeks?
    “Gitana 13 will remain in Yokohama until early May, since we’re continuing our series of records in the China Sea. The next destination for the crew is Dalian, in China, after a 1,500 mile record crossing attempt between the two towns. We will then follow that by trying to set new record times between Qingdao, Taipei, Hong Kong and Macao, prior to returning to Hong Kong to set off on the Tea Route.”
