  • 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.

    The storm diminishes for Gitana 13.

    The storm which passed over the tip of South Africa this weekend fully lived up to expectations! Though gusts onshore did not exceed 55 knots, at sea the wind was more violent.

    The storm which passed over the tip of South Africa this weekend fully lived up to expectations! Though gusts onshore did not exceed 55 knots, at sea the wind was more violent. Indeed, to the immediate south of Port Elizabeth the average wind reached 55 knots with gusts approaching 80 knots. Fortunately the maxi-catamaran in the colours of the LCF Rothschild Group was able to reach Algoa Bay off Port Elizabeth on Saturday evening, less than an hour before the arrival of the cold front, so they were a little less exposed to these extreme conditions.

    Dominic Vittet describes the living conditions and navigation from their shelter: “Since Saturday evening we’ve been going back and forth barepoled, remaining as close as we can to the coast. During the course of yesterday the onboard anemometer recorded a gust of 67 knots, but Port Elizabeth really was the right choice as we’re very well protected here. The swell put in an appearance yesterday evening at the bottom of the bay, but nothing dramatic. On the other hand, just one or two miles downwind of us, there are big seas and you can make out the crests of the breaking waves.”

    This pause is not dissimilar to the five day wait the crew of Gitana 13 were forced to endure at Cape Horn last January during the Route de l’Or. However there is one very big difference: “We are sheltered and the boat isn’t suffering so the crew is managing to relax. It’s nothing like the atmosphere during the standby at Tierra del Fuego either. In January, the days where we were stopped were also synonymous with total isolation, whilst here we’re really just a stone’s throw from the town and numerous oil tankers, cargo ships and commercial vessels are taking refuge like us. The situation is fairly unique!”

    The crew of the maxi-catamaran are benefiting from this ‘downtime’ to rest. Indeed with Gitana 13 currently sailing barepoled, the tack changing manœuvres amount to rotating the mast and moving the mainsail traveller; a task which is easily achievable for the three men on watch: “The boat is highly fluid when barepoled and the crew on watch is largely sufficient on deck. As a result we’ve got rid of the standby watches whilst we’re stopped so that the boys can benefit from 6 hours in a row of sleep” explained the skipper of Gitana 13.

    The reasons for this are that they’re going to need their strength in order to tackle the rounding of the tip of South Africa, as the skipper of Gitana 13 confided: “Over 300 miles separate our place of shelter and the Cape of Good Hope. We’re going to have to make a series of tacks upwind in what will still be a steady breeze and big seas. We’re going to have to endure a bit of pain in order to make the Atlantic.”

    The crew of the maxi-catamaran equipped by Baron Benjamin de Rothschild will have to find the right weather window to head back onto the racetrack, a time slot on which Sylvain Mondon is working: “This Monday, the wind is a lot less strong. The last squalls have passed and the gusts have died down overnight. However, it will be best to be patient before rounding the Agulhas Cape and the Cape of Good Hope, as there are still very big seas this morning with waves continuing to reach 7 to 8 metres in the 5 mile coastal strip and in excess of 10 metres 30 miles offshore. This big, powerful swell becomes more abrupt when it encounters the Agulhas current along the SE coast of South Africa and it’s worth taking note that this region is notorious for its ‘heinous waves’. Prudence will remain paramount for Lionel Lemonchois and his crew, who won’t be able to leave the bay of Port Elizabeth until there is a significant calm in the swell along the coast.” At present, this lull is expected this evening.
