  • 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.

    A relentless North Atlantic for Gitana 13.

    Aboard the maxi-catamaran in the colours of the LCF Rothschild Group, the climb up the North Atlantic is revealing all its subtleties… and its difficulty. Slowed considerably by a long passage across the Doldrums late last week, Lionel Lemonchois and his men are now faced with a meteorological brain-teaser off the Canaries. This will be a tricky section, as will the Bay of Biscay and the last few miles along the English Channel. In plain language, positioned 1,700 miles from London this Thursday afternoon, the crew of Gitana 13 will have to hang on patiently before they can reach their goal.

    Sailors have a great capacity to constantly adapt to the changes in weather. However, when they’re down to the final miles and home is not too far away – at least compared with the 13,000 miles they’ve covered since leaving Hong Kong – the desire to complete their mission is becoming increasingly pressing!: “This morning, whilst the forecast grib files didn’t bode well and we were making slow headway at 10 knots in a capricious wind, I have to say that the troop’s morale wasn’t great… However, we’ve had some new, more optimistic grib files since then and the good humour has returned. In the last days of a long voyage like the Tea Route, the atmosphere is always split between the desire to get there and the nostalgia of returning home” confided Lionel Lemonchois.

    As regards the weather, the ten sailors of Gitana Team know that they can count on the talent and the receptiveness of Sylvain Mondon to try to evade the pitfalls dotted across their course. In fact the telephone and email exchanges between the onboard navigator and the onshore router have been numerous recently: “Gitana 13 is sailing upwind on the approach to a stormy low with N’ly winds fluctuating at the mercy of the associated cold air. This is why the crew are making headway at a moderate speed of between 10 and 15 knots. This is set to be the way of things for some time and in fact the situation may become more exaggerated tonight and tomorrow morning. Indeed, in around twenty hours time, the maxi-catamaran will begin the most tricky phase to the south of the low in fairly light winds. This transition zone located immediately to the NW of the Canaries will nevertheless be an important passage as the winds will then fill in slowly to start with, before increasing as they shift round to the west and then the south-west during Friday” explained Sylvain Mondon before concluding: “From then on, Gitana 13 will be able to slip along downwind at speeds in excess of 20 knots, which will enable it to close rapidly on Cape Finisterre over the course of Friday night”. This change in pace is something the ten sailors have been looking forward to, but for the time being they’re paying a high price for it.

    Setting out from Hong Kong on 14th August 2008, Lionel Lemonchois and his nine crew attacked their sixth week at sea this morning, and sincerely hope it will be their last. Indeed, though an exact ETA is very difficult to provide today, everyone is agreed on an arrival at the entrance to the River Thames between 23rd and 25th September. In the meantime, the Bay of Biscay and the English Channel await, and it’s certainly not going to be an enjoyable ride: “From Sunday, the wind will have continued to swing round so that the crew are faced with an E’ly wind at the approach to the Bay of Biscay. More close-hauled sailing is in store for Gitana 13 then in a steady E to NE’ly breeze as they traverse the Bay of Biscay and make the climb along the English Channel. The ten sailors of Gitana Team will have to make a series of tack changes as far as Pas-de-Calais so the last few miles will be extremely strenuous. Doubtless the climb up the Thames in downwind conditions will be a relief for the whole crew, even if the river traffic will warrant increased vigilance all the way to London.”

    Gitana, a passion for sailing
    Spurred on by Baron Benjamin de Rothschild, the Gitana story opened towards multihulls in 2000 with Gitana IX. An ‘armada’ followed with Gitana X in 2002, Gitana 11 (Ex-Belgacom) in 2004, then Gitana 12 (Ex-Bonduelle) in 2006 to replace Gitana X. In 2007, a year after the arrival of Loïck Peyron at the head of the Gitana Team, the fleet diversified: Gitana 11, the 60 foot Orma multihull and outright winner of the Route du Rhum 2006, was then accompanied by Gitana Eighty, a 60 foot Imoca monohull, and Gitana 13, a 33 metre maxi-catamaran was devoted to discovery.  Crewed records for Gitana 13 and solo races for Gitana Eighty: this new season already promises to etch some fine lines in the histories of the Gitana boats…
