    • 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.

    Having cast off from Lorient in the early hours of this Sunday morning, the Maxi Edmond de Rothschild crossed the start line off the island of Ushant at 13h 9 min 30s UTC in her attempt to secure the Jules Verne Trophy. At the helm of the 32-metre giant, Charles Caudrelier, Franck Cammas and their four crew are taking on the prestigious round the world race against the clock. The aim: to beat the record of 40 days, 23 hours and 30 minutes set in 2017 by Francis Joyon and the men of IDEC. To achieve this, Gitana Team will have to make it back to Brest and the Le Créac’h lighthouse before 25 March 2023 at 12h 38min 59s UTC. Though rather unique, the weather window on offer to the Maxi Edmond de Rothschild is certainly worth a go, as there might well be a series of great opportunities for the five-arrow crew to snap up along the way.
    A far from standard weather window

    Since Friday morning, the skippers of the Maxi Edmond de Rothschild and their router, Marcel van Triest, have been eyeing up a serious opportunity to finally get things underway in their sprint around the planet. However, from one grib file to the next, a series of discrepancies have made a tough choice even harder for the weather cell. Ultimately, true to the team’s philosophy of being bold and committed, early this Sunday afternoon the large flying trimaran fitted out by Ariane and Benjamin de Rothschild set sail on this iconic record of offshore racing.

    Like Charles Caudrelier, all the members of Gitana Team freely admit that “the weather window is rather atypical,” a choice that the recent winner of the Route du Rhum-Destination Guadeloupe explains in more depth: “though we have a very precise idea of what may happen in the North Atlantic, the same cannot really be said in the South Atlantic. A low pressure system to the south of Brazil is a little uncertain according to the weather models.”In short, the team will have to locate “a bolt hole”, says Morgan Lagravière and “have a bit of luck with the sequence of weather systems,” continues Franck Cammas. However, the first few days at sea have been well identified with “upwind conditions to start and a front to hunt down tomorrow,”explains Erwan Israël. If the weather sequence subsequently proves less favourable, the crew reserves the right to turn back level with the Canaries in a bid to hunt down a better launchpad from the tip of Brittany.

    Focused, determined and particularly enthusiastic, the six crew on the Maxi Edmond de Rothschild have set sail on their first attempt of the year, the third in all for the Verdier design following two aborted campaigns in 2020 and 2021. The latter came to an end after 12 days of racing at the entrance to the Southern Ocean, with the team ahead of the record having just secured the best ever time to the Agulhas Cape. Though setting sail in mid-February might appear quite late in the season, some has set off even later in the day, including Sport-Elec (Olivier de Kersauzon, on 8 March 1997) and Orange II (Bruno Peyron, on 2 March 2002).

    Charles Caudrelier, Franck Cammas and their crew now have their eyes glued to the upcoming waypoints, particularly one offshore of South Africa. “We need to have a lead of at least 24 hours over Francis Joyon’s passage time at the Cape of Good Hope (12 days, 19 hours),” stresses Charles. As a result, the team has a set of well identified goals and the race against the clock is most definitely on!

    Quotes of the crew:

    Charles Caudrelier: “It’s a fairly atypical weather window, but we’re getting to the end of standby and we’re keen to give it a go, especially with the grib files indicating some good passage times yesterday evening. Though we have a very precise idea of what may happen in the North Atlantic, the same cannot really be said in the South Atlantic. There’s a low pressure system to the south of Brazil, which is a little uncertain according to the weather models. However, we’ve decided that it was worth having a go, even if we have to turn back when things don’t play out that way. The aim is to get as far as possible. One of the areas where we can gain the most time in relation to the previous record is in the Atlantic. We need to have a lead of at least 24 hours over Francis Joyon’s passage time to the Cape of Good Hope (12 days, 19 hours). He set the bar very high and we know his record is going to be a tough nut to crack. The toughest thing about this record is managing to finish with a boat at 100% of her capacity. That said, we believe the Maxi Edmond de Rothschild has reached maturity!”

    Franck Cammas: “It’s the first time we’ve crossed the start line this year. We’re well aware that if we are to pull off this record, it’s important to have a bit of luck on our side with a good sequence of weather systems. The days we lose during the first phase could well be detrimental to the record, which is why we’ve taken time to set sail. We cannot afford to waste any time, especially as the reference time posted by Francis (Joyon / IDEC) is very good in the southern hemisphere! To break records, you first need to have a go.”

    Morgan Lagravière: “I wasn’t really worried about whether we’d set sail. When you see how dynamic Charles and Franck are, we knew we were going to go for it. It’s a powerful moment, it’s also a moment when you’re bidding farewell to family, so emotions run high and there’s a sense that you’re united in the moment. Overall, it’s a very positive sentiment. After that, we have to keep a cool head as we know that there are a fair few uncertainties with this weather window. We really want to get down into the Southern Ocean. It’s a box I’m yet to tick in my career. The boat’s exceptional, the crew’s excellent: these are very good conditions for enjoying ourselves and doing something truly unique. We’re going to believe that luck is on our side and that the planets are aligned in terms of the weather.”

    David Boileau: “Naturally, our mindset is a conquering one! We’ve been waiting for a month and a half so inevitably we’re very happy to be setting sail. There’s a sense of release for all of us. We know that the weather window isn’t great, but we’re going for it and we’re going to try our luck. If the weather doesn’t prove so favourable, we’ll turn back and we’ll wait for the next one. However, things are moving forward and we’re keen to have some fun and give our all!”

    Erwan Israël: “It’s only the second time I’ve changed my clothes in the boat since the start of standby (laughs)! Ultimately, we’d never really planned to set sail, but this is the one this time! Inevitably, we were all a bit fed up with standby and monitoring the weather… Right now, we’re delighted, we’re all smiling and we believe in it. Though there is some uncertainty, the North Atlantic is pretty good and the weather window is interesting. We’re going to head upwind and hunt down a front tomorrow, which makes the challenge all the more appealing!”
