  • 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.

    Decidedly the weather is doing nothing to spare the sailors competing in the Transat Jacques Vabre. After a tactical start to the race in the English Channel, playing with the currents in relatively light winds, the fleet got straight to the point yesterday with the negotiation of a very deep depression. Aside from the Class 40s that is, which are still sheltering in Roscoff. Heading the pack, the two Multi70s have, as forecast, devoured the Bay of Biscay at high speed. However, this express crossing hasn’t been much fun. In messy, heavy seas (5-metre waves), the trimaran Edmond de Rothschild and her rival have had to jump off waves coming at them side on in a steady breeze that often picked up to beyond 30 knots leaving very uncomfortable, stressful conditions for Sébastien Josse and Charles Caudrelier.


     

    An express but testing Biscay

    The images shot* by a surveillance plane from French customs late yesterday morning as Edmond de Rothschild and her adversary were making headway around the Raz de Sein, offshore of Brittany, give some indication of the sailing conditions over the past 24 hours. However… “They had a lot bigger seas and wind afterwards as they traversed Biscay,” explains Antoine Koch, the onshore router for the Edmond de Rothschild duo.

    Despite the Multi70s carving out a long diagonal wake, the negotiation of the Bay of Biscay proved tricky. In seas swept by a substantial north-westerly swell and winds of between 25 and 30 knots, the trimarans and the sailors were given a rough ride. Indeed in an incessant din comprising a mixture of cracking carbon and waves slamming violently against the hulls, it was tough for Sébastien Josse and Charles Caudrelier to get some shut-eye or even to rest as they waited for their next stint at the helm. Added to that, the instability of the wind called for a series of sail changes from the crew and constant attention from the sailor in charge of the tricky piloting manoeuvres.

    Weaving wildly to the north of Spain

    The duo had hoped to find more manageable conditions as they approached the Spanish coast, but to no avail alas! “It was a lively night for them,” Antoine explains from HQ in La Rochelle, where he’s working day and night in collaboration with the meteorologist Jean-Yves Bernot. “The depression we’re concerned with right now has deepened and to the south of the front, the wind has been stronger and further over to the left than forecast”. Inevitably there are direct consequences of this for Sébastien Josse and Charles Caudrelier: “On the approach to Spain, the wind was set to ease a little. That hasn’t really been the case and instead they’ve had to link together a series of tack changes in really tricky wind and sea conditions. The north-westerly swell is still significant (4 to 4.5 metres) and those stretches on port tack, that would enable them to head offshore, have been really very hard with huge head seas.”

    This morning, the trimaran fitted out by Baron Benjamin de Rothschild had set a course to the South along the Iberian Peninsula, bound for Cape Finisterre. The Josse-Caudrelier duo’s troubles still aren’t over though: “the south-westerly wind is taking its time to ease. They still have 25 knots, but that should drop to around 20 knots this afternoon. They’re on a reach (wind on the beam) with a continued swell and though progress should be fast, it’s not the most pleasant point of tack on these boats. This is particularly true given that in cold wind the gusts are stronger and more dense,” Gitana Team’s router concludes.

    At the 0700 GMT position report, the two Multi70s were virtually neck and neck but Sébastien Josse and Charles Caudrelier were holding onto first place, just a little over a mile ahead of Oman Air – Musandam.

    Please note that there are six official position reports a day at the rate of one report every 3 hours from 0400 hours. No position reports are produced overnight and from 1900 GMT, a position blackout is observed. Timing of the official rankings: 0400, 0700, 1000, 1300, 1600 and 1900 hours GMT.
