  • 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.

    At the front of the Transat Jacques Vabre fleet, the trial of strength that the two 70’ trimarans have been involved in since leaving Le Havre some six days ago, will be stepped up a gear over the coming hours. Leading the way since the start of the race, Edmond de Rothschild boasted a 78-mile (150km) lead over Oman Air-Musandam this Wednesday at 1530 GMT. As a result Sébastien Josse and Charles Caudrelier will be the first to enter the tricky Doldrums region, which is situated above the equator, whilst Sidney Gavignet and Damian Foxall have opted to position themselves 100 miles (180km) to the East of their rival.

    In this so-called inter-tropical convergence zone, both the navigational instruments and the sailors are unable to make head or tail of the situation. Indeed, when the tradewinds of the northern hemisphere meet their counterparts from the south, they cancel each other out leaving a rather unpredictable zone in their wake. In a humid heat, the sailors attempt to make headway between the violent squalls and what becomes a ‘crazy’ wind beneath the massive cumulonimbus. Of varying width and in more or less of a northerly position, the Doldrums are a nightmare for strategists. Solely satellite images give some insight into the density of the cloud and the general activity in the zone. In this way, despite all the digital tools at their disposal, the navigators initially focus on what they can see around them in order to extract themselves from the area as quickly as possible.

    Theoretically well placed

    There are a few rules for tackling the problem in the right manner however. To start with, the first to enter the Doldrums is often the first to come out the other side. Edmond de Rothschild already holds this particular card. After that, ordinarily the unstable zone is narrower to the west than in the east, near the African coast, which is the case right now. Here too, Sébastien Josse and Charles Caudrelier appear to be well placed. “Even though we’re entering a very random period of the race, we prefer to position the trimaran Edmond de Rothschild between our rival and the western side of the race zone,” Antoine Koch, the router of the boat fitted out by Baron Benjamin de Rothschild confirms at midday.

    Not simple for all that

    Nevertheless, with this particular Doldrums spanning nearly 300 miles in width, as well as being rather active and very far north (from 8degrees north), it’s likely to be a complicated task. “We put in a gybe as a preventative measure to line ourselves up,” Sébastien Josse stated at this morning’s Transat Jacques Vabreradio session. “We should make it into the Doldrums over the course of today and we’ll have to wait and see when we’ll come out the other side, but we hope it will be fairly soon! Sometimes it goes without a hitch and other times there’s a squall which blocks your progress for hours on end.”

    Sailing beneath the clouds enables progress to be made towards the exit, even though the wind can go from 5 to 25 knots in a matter of minutes. As such the crews will have the afternoon to familiarise themselves with the situation, but the ‘cloud-hopping’ section will largely be played out by night. “It won’t be easy,” the router continues: “The very big cloud masses will show up on the radar, but it’s on deck that the sailors will get the best handle on the situation. We’ll have to deal with every eventuality as it arises.”

    A just-in-time policy

    After the first three days of racing in a tough weather system, then the three following days at high speed in the trades, the Edmond de Rothschild duo are keeping control of this thrilling hand-to-hand battle with Oman Air-Musandam.

    However, at the midway point in the race, the boats remain very close to one another and a fresh trial is beginning. Indeed, each crew is having to leave part of its fate in the unpredictable hands of the ‘Doldrums’. This will come as added weight on the shoulders of these sailors, who will be constantly wondering whether the other boat is fairing better than them.

    Fortunately Sébastien and Charles are attacking this tricky phase in fine fettle. The stability of the wind conditions over the past few days has enabled the duo to adhere to regular watches and allow themselves several two-hour stretches of sleep in a row… Suffice to say that this is the height of the luxury!
