  • 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 six days of racing, the leaders of the Coffee Route are negotiating their first passage through the doldrums, the notorious and dreaded inter-tropical convergence zone located a few degrees to the north of the equator. Heading the fleet, the Maxi Banque Populaire XI was the first to cross its threshold this afternoon and has stalled dramatically over the past few hours. In her wake, in 2nd place, Charles Caudrelier and Erwan Israël are making the most of the situation to claw back every possible mile, well aware that in this constantly shifting zone, opportunism and quick reactions are vital. A sentiment heightened by the fact that just astern of the Maxi Edmond de Rothschild, the rest of the fleet is poised to pounce, starting with the Gabart / Laperche duo.
    Keeping up the pressure

    After setting sail from Le Havre last Sunday, the ULTIMs, currently the only fleet out on the racetrack in this Transat Jacques Vabre, are focused on traversing the doldrums this Saturday as they make their way towards the equator.

    During this morning’s radio link-up, Charles Caudrelier gave a brief low-down of the past few hours of racing in what has been an intense first week at sea, during which the five-arrow giant has covered nearly 3,000 miles, or the equivalent of a transatlantic passage: “Yes, it’s tiring. The race is tiring and for now the rich just keep getting richer… We’ve been making headway directly in the wake of Armel (on Banque Populaire) by putting in lots of gybes, whilst he’s been on a straight-line course! In fact, we’ve been manoeuvring a great deal over the past few hours. The breeze has been strong with unpleasant seas, so it hasn’t been easy to find the right balance between the autopilot and the helm as the pilot has been struggling to perform well and after a while we tire at the helm. We’ve also had a few issues to deal with too so we haven’t been able to go very fast on this long tack. We’re all shipshape again now though, so we just need the doldrums to give us a bit of help to close on Banque Populaire, which has been sailing a very fine trajectory and a great first section of the race. That way we can go on the attack at the end of the course where there are two quite interesting sections to negotiate. It’s worth noting that we’re not at the halfway mark yet. There’s still a long way to go!”

    Meteorological toll to pay before the southern latitudes

    All round the world sailors are familiar with this zone, as it is a compulsory passage to gain entry to the southern hemisphere. Some dread it, whilst others have a more fatalistic approach. One thing for sure, this inter-tropical convergence zone, where the warm masses of air from the NE’ly trade wind collide with those of the SE’ly trade wind, is never short of surprises be they good or bad!

    Charles Caudrelier was keen to point out today that he’d traversed the doldrums more times in his career than he’d rounded Cape Horn, so he had plenty to say on the subject: “Right now, the doldrums look fairly easy. I don’t know that it’s a good thing for us as we’re behind, but according to the latest observations the clouds are not very dynamic. I’ve experienced far worse doldrums passages. The negotiation of this zone can be a tense passage, but that was especially true during the days of ORMA or the MOD70, as they were the kind of boats that were a bit full-on when they were carrying too much sail. We have a bit more leeway. The boat is bigger, so she requires a little more manoeuvring, but she’s better at coping with being hard pressed, which is reassuring. We also have more and more anti-capsize systems now and we’re routed, so our weather cell warns us of any squalls. As a result, the key stress factor relates to reefing and finding ourselves without enough power. Each time that happened, my main stress was that I would be overtaken whilst I was at a standstill… In fact, back in 2021 with Franck during this same race, we entered the doldrums with a good lead – 200 or 300 miles – and it was Armel who almost managed to pull level with us. What’s more, it was just at the exit gate that we were able to extend away again by escaping the zone a fraction earlier. It is sometimes the case that something minor can make all the difference: one cloud, one line of squalls. Our boats can negotiate the doldrums very quickly. If there’s just a sniff of breeze, we can very quickly pick up the pace to 20 knots and we don’t have to endure a rather laborious 300 miles for half a day. We can also take double that time or worse if there’s no breeze. It can be a whole different ball game depending on your passage time. Things change very quickly from east to west in this zone so you have to monitor the on-board radar and the satellite images from our routing cell. There are no magic solutions in the doldrums and experience does not give you greater certainty. It’s a constantly shifting zone and you have to be able to read between the lines of clouds.”

    On shore, Gitana Team’s entire weather cell, which this year comprises Erwan Tabarly, Simon Fisher and Chris Bedford, has been mobilised. The guys are taking turns to remain glued to their computers 24/7 to help map out the best possible route for the crew of the Maxi Edmond de Rothschild. Since this morning, they’ve been pouring over the weather forecasts and the satellite images in particular so they can constantly adjust their real-time exit trajectory for the equator and the southern hemisphere.
