  • 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.

    Patience and concentration.

    For several days, the succession of grib files which Franck Cammas and Charles Caudrelier have been studying with the router and 7th man, Marcel van Triest, have been in agreement that it will soon be time for the Maxi Edmond de Rothschild to cast off and set sail. This Thursday, all the lights are taking on a strong yellow hue as they prepare to switch to green. All the members of the five-arrow racing stable have been on the alert for the past few days so as not to let slide this fine opportunity taking shape ahead of the offshore charger’s bows. This Saturday 9 January 2021, the six sailors on this trimaran designed for oceanic flight could well make for the start zone off the island of Ushant with a view to setting sail on this outright round the world record attempt.

    “We’re attacking the start of the 3rd month of standby… It’s a long time, but there have been times where we’ve been certain that nothing interesting would happen in terms of the weather. During that time, we can turn our thoughts to other things and practice some sport. And then there are situations, like those of recent days, where we’re eyeing up a departure and hesitating… That involves a bit of travelling around and a series of PCR tests… And then in the end we don’t leave. These more uncertain periods are a bit less fun. We’re on the alert and it’s more complicated for the nerves, especially with regards family. We say goodbye to the children, but we don’t know if it’s going to be for 3 days… or 40 days. The ideal standby occurs when it doesn’t take too long and an extraordinary window presents itself after a week or a fortnight. Unfortunately, that’s not the way things have played out.

    Right now, there’s a departure situation settling into place with a lot of downwind conditions and N’ly winds generated by a zone of high pressure. That’s giving us a slightly broader target window. However, there’s also a zone of low pressure, which is blocking the way a little at the start. It’s fairly violent, so we’d like it to roll across to the east so we have a clearer passage through to the trade wind. We’d like to set off as late as possible, but waiting around also carries the risk of us ending up in a position where we don’t have any breeze at all on the start line.”

    “It’s my first standby. I’ve never experienced this type of preparation and this waiting period before. It’s a special time, but I’m lucky to be in contact with people who have already had to negotiate this type of experience. It’s part and parcel of such a challenge. For the past two months, we’ve had several situations where we were ready to leave and we even set sail once before quickly turning back. These attempts within an attempt are good training and help us ready ourselves in terms of gear and also on a more psychological level, to ensure we’re in race mode the minute we cast off and bid farewell. These are demanding boats after all and an error is never far away. You really have to concentrate from the get-go. That said, it’s fair to say that as time goes on, the more eager you are to set sail… At that point it’ll be time to go for it, which is fortunate as now’s the right time! 

    Since Tuesday evening, a variety of possible options have opened up, with a fairly long window in the North Atlantic, which enables us to wait and see how things evolve in the South Atlantic. We’re going to gradually increase the pressure and finish off the final preparations. The boat is ready to go. She’s loaded with provisions and all that remains is to add a little fresh produce and head towards the start line!”
