  • 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.

    After a long weather briefing carried out remotely with the router Marcel van Triest, the entire crew of the Maxi Edmond de Rothschild gathered alongside Cyril Dardashti, director of the five-arrow team, has taken the decision to switch to code yellow, with a possible departure in a little over 24 hours. Although the weather models are still refusing to indicate a perfect window, Franck Cammas and Charles Caudrelier, the two skippers, are keen to give themselves a chance of setting sail to conquer the Jules Verne Trophy and make their own luck by crossing the imaginary line offshore of Brest early evening tomorrow, Tuesday 24 November.

    To set sail, or not to set sail? That is the question.
    This Monday, their actual departure is still cloaked in doubt and a great deal of uncertainty. Though everything is coming together to guarantee the right weather conditions at the start with the prospect of making the equator within a very respectable timeframe, for now the South Atlantic remains less inclined to offer up the ideal context to give free rein to a hassle-free descent on the quest for a sequence of low-pressure systems in the Southern Ocean. Due to the Saint Helena High, which is making forecasts very tricky, there’s a risk that in ten days or so, the favourable winds may escape the sails of the Maxi Edmond de Rothschild, slowing progress in her hunt for the outright round the world sailing speed record. On one model, it works; in the other, the crew gets stuck.

    Uncertainties in the South Atlantic

    “Today, on both the American and European models, the situation is relatively clear for the start, provided the crew sets sail shortly before a front rolls through, behind which conditions will deteriorate with the arrival of a small mobile ridge of high pressure with lighter winds”, explains Marcel van Triest, the boat’s 7th man, who is studying and analysing the situation. This top Jules Verne Trophy expert remains very confident with regards to the crew’s chances of kicking off its fabulous ride in style. “Even though it varies a little from one model to the other, including a 6-hour deal to negotiate the doldrums, there is every chance that the crew can make the southern hemisphere in 4 days and 12 hours. However, that’s where the situation becomes complicated and blurred”, he adds. “We’re faced with a very shifty situation that is evolving quickly. The danger is that we’ll miss the train and get crushed between two areas of high pressure in the South Atlantic. It poses a real threat, even though there is still a possibility of linking onto a course that takes us behind the high pressure. Right now, in this very progressive system, it’s circulating very low down in the south.”

    Possible departure from Lorient at midday tomorrow

    With regards to this situation, albeit driven by a real urge to set sail and attempt to break the record time of 40 days, 23 hours and 30 minutes held since January 2017 by the crew of Francis Joyon, Franck Cammas and Charles Caudrelier are eager to give themselves every opportunity to snap up this late November weather window, which remains ajar today. This evening and tomorrow morning, they’ll study the situation again with the analysis of the new weather models. In the meantime, the six men who make up the crew are preparing to board the boat at midday tomorrow for a departure from the team’s base in Lorient, Brittany, at midday. At that point, they’ll set a course for the imaginary line between Le Créac’h lighthouse on Ushant and Lizard Point so this area offshore of Brest will be the start and finish destination for this planetary circumnavigation, which they have every intention of completing at full speed aboard their flying boat.

    REMINDER OF THE STANDBY CODES

    During the period of standby for the Maxi Edmond de Rothschild, which the five-arrow team has scheduled to run from 1 November to the first few days of February 2021, any changes in the situation and a possible departure date for the boat are announced via a colour coding system as detailed below:

    Black: no departure possible within 96hrs 
    Red: observation of a possible departure between 72 and 96hrs 
    Orange: observation of a possible departure between 48 and 72hrs 
    Yellow: probable departure between 24 and 48hrs 
    Green: departure within 24hrs
