  • 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.

    There are no days off in the open ocean! For Franck Cammas and Charles Caudrelier, leaders of the Transat Jacques Vabre in the Ultime category, there is certainly no time to relax. After a Bay of Biscay, which saw the giants breaking records for the slowest speed under the influence of a ridge of high pressure, a bracing passage around Cape Finisterre and a physical descent along the Iberian peninsula, the duo on the Maxi Edmond de Rothschildleft Madeira abeam of them this Thursday morning. In this way, she’s leading all the fleets southwards, but ahead of the five-arrow giant’s bows, the weather situation is still just as vague and the trade wind isn’t really playing ball.
    A gybing corridor

    Since Tuesday afternoon and the start of their negotiation of the north-west tip of Spain, the duo on the Maxi Edmond de Rothschild and their Ultime rivals are linking together manoeuvres and sparing no effort in a bid to remain in a steadier corridor of breeze stretching out towards the south-west. In 48 hours’ time, Franck Cammas and Charles Caudrelier have put in no less than eighteen gybes! An impressive figure for anyone who’s previously sailed aboard the Verdier design, given how much physical effort is required, but it just goes to show how committed and motivated the men of Gitana Team are at the head of the race. “Franck and Charles are very focused and have been sailing a very clean race since the start. We’re hunting down the slightest rotation in the breeze and there’s plenty to keep an eye on at the moment, both on shore and at sea, due to the significant cloud cover. We’ve really had to be on top of our game to make the most of the corridor of breeze and hold onto the maximum pressure, a feat they’ve managed to perfection”, admitted Erwan Israël, one of the men that makes up the Maxi Edmond de Rothschild’s routing trio.

    All out west

    The descent of the North Atlantic has a succession of islands strewn across it: Madeira, the Canaries, Cape Verde. Though these names conjure up images of sunny destinations, for the sailors and their weather cell, they are primarily synonymous with wind shadows and the associated stalling. In addition to the weather conditions that naturally colour play in the area, it is these islands, some of which culminate at over 3,718 metres (Teide, in the Canaries) and their effects, which must be taken into account when deciding which strategy and trajectory to adopt over this section of the race: “Today, the aim is to distance ourselves from the Madeira archipelago so as not to be affected by the wind shadow created by its islands. We’re looking at the satellite photos of the disturbances over a 100 miles to the south-west. The same is true for the Canaries, which we’re targeting tonight. We’ve noted that the whole Ultime fleet has followed suit”, explained Erwan Israël, before giving us the low-down on the upcoming conditions: “The overall situation is still the same. We have a major low pressure system in the North Atlantic positioned quite far south. This low pressure is disrupting and pushing back the zone of high pressure eastwards, which has the effect of breaking up the trade wind system. We made the most of what we refer to as the Portuguese trades along the Iberian peninsula to make headway at a good pace, but unfortunately the NE’ly trade wind in the northern hemisphere has not established itself and is set to be light for the coming days. We’re going to have to be opportunistic, as we have since the start, and adapt to the evolution in the weather models.”

    A new hierarchy

    Heading the fleet since the first few minutes out on the racetrack, Franck Cammas and Charles Caudrelier were dominating play as far as the north-west tip of Brittany, where the breeze completely dropped away on Sunday night through into Monday, reshuffling the cards in the process. In the erratic winds and the meteorological brainteaser, there was constant jockeying for position at the front of the pack throughout the passage across the Bay of Biscay. By opting for an E’ly trajectory, accompanied by SVR-Lazartigue, the skippers of Gitana 17 came out on top as they tackled the passage around Cape Finisterre. In a beefier breeze, the Maxi Edmond de Rothschild and her crew showed just what they were made of, snatching back the lead on Tuesday evening; a position which the Caudrelier-Cammas duo are still holding onto this Thursday.

    Astern of them, the hierarchy has been shaken up in more ways than one. Last night, Sodebo, which was lying in second place at the time, unfortunately damaged her starboard foil after colliding with a UFO. Since then, the two skippers have been in slo-mo and we’re still awaiting more information in the hope that they’ll very swiftly be able to get back out on the racetrack. SVR-Lazartigue has made the most of the situation to slip into the runner-up spot, whilst Banque Populaire XI has entered the top 3. Fourth placed Actual isn’t far off the pace and there is still precious little separating the Ultimes at the start of this race.

    Images from the ocean, day 4 – abeam of Madeira

    This Thursday morning, after four days at sea, the head of the Transat Jacques Vabre fleet is passing the Portuguese archipelago of Madeira. In the lead for more than 24 hours, Franck Cammas and Charles Caudrelier have spared no effort in getting the five-arrow maxi-trimaran making headway and making the most of the corridor of breeze ahead of the bows of the 32-metre giant. They’re reaping the rewards now, slipping along with a beautiful sunrise to boot: “We’ve got around fifteen knots and we’re making more than 30 knots, we’re flying…!” assures Franck Cammas from the cockpit of the Maxi Edmond de Rothschild.
