  • 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.

    Gitana back in the Atlantic.

    After having spent 6 and a half days at sea and covering some 1,660 miles (3,074 km), Gitana has returned to her home port of La Trinité-sur-Mer, completing her qualifying passage for the two-handed Transat Jacques Vabre race into the bargain.

    After having spent 6 and a half days at sea and covering some 1,660 miles (3,074 km), Gitana has returned to her home port of La Trinité-sur-Mer, completing her qualifying passage for the two-handed Transat Jacques Vabre race into the bargain. A highly instructive training session for the boat’s skipper Lionel Lemonchois and her navigator Marc Guessard, the duo comprising the crew fro this express delivery.

    Even if this is not a speed record – changeable weather conditions – the pair did drive Gitana as fast as possible to bring her back to Brittany, pulling out all the stops as they finished crossing the Bay of Biscay. Lionel Lemonchois : …it was brilliant. A north-westerly wind picked up to around 25 knots (46 km/h). The sea had not started to swell. With two reefs in the main and the small working jib up, we sped along for 150 miles (280 km) at between 27 and 31 knots (50 and 57km/h). We made an average of 25 knots (46 km/h)“. Marc Guessard : “…it was magical to fly along like that in the middle of the night…”

    During this short week at sea, the two sailors had the opportunity to fine tune their complementarity for the season’s leading event which sets out of Le Havre (Manche) on 2nd November bound for Bahia (Brazil). Marc Guessard : “…It’s a first for us on this sort of boat. We needed to see how to sail her two-handed out on the open sea. We got some incredible sensations. Helming on your own in the middle of the night at 20/25 knots (37-46 km/h) when your fellow crew is asleep, is a rare experience, even if it’s hard. Ditto when you are falling asleep and you can hear the boat vibrating all over and that there is someone up on deck sailing her fast …”.

    No doubt about it, Lionel and Marc have made a major advance in their preparation for this short-handed transatlantic race, and particularly fine tuned their connivance. Marc Guessard’s impressions : “… I had a great time. Such a small crew on such a big boat – you feel so small when you have to manoeuvre. But I’m lucky to have a great teacher. Lionel is really at ease and always calm. It’s impressive to watch him at work…”.

    A compliment which the trimaran’s skipper receives with irony: “…let’s hope that it lasts ! …We asked Marc months ago if he would like to come and sail this race with me. He was able to make himself available and I’m really pleased about it. I already appreciated him two years ago on another trimaran for his crew management qualities. He does an excellent job of that on Gitana. Today he confirms that he is an excellent co-skipper. There aren’t that many people in fact with whom I could sail two-handed. Marc is one of them…”.

    Back into the shed

    As from Monday, Gitana is going back to her original builder, Multiplast, where she will be hauled out for two or three weeks for the first mid-season improvements (cf Previous press release “After Marseille” on www.gitana-team.com). Lionel Lemonchois : “…We’ll be staying there as little as possible before the Grand Prix de Fécamp, and then getting back to training. She’ll be back in the yard in September to complete the improvements and the preparation for the Transat Jacques Vabre…“.

    The Gitana Team has therefore embarked upon a rather studious summer interlude to be fighting fit for the 4th Grand Prix of the Ocean-Racing Multihull Association (ORMA) World Championship in Fécamp (Manche) from 28th to 31st August.

    Looking back over a short week at sea by Marc Guessard

    Wednesday 9th July – Start

    Left La Ciotat (next to Marseille) at the end of the day, after two days spent preparing and fine tuning the boat to be sailed two-handed. Manageable head wind.

    Thursday 10th July – Day 1

    Wind now following. Clam sea. Boat just slips effortlessly along. Calm conditions lie ahead as we approach Majorca. Gennaker (big balloon jib) up.

    Friday 11th July – Day 2

    Wind increasingly changeable. Gitana under engine power off Majorca. The island looks really desert-like and mountainous. We’re using the return of the wind to sort out the finer adjustments of our automatic pilot. Gybing downwind and in the evening we should pass Alicante on the coast of Spain to enter the Alboran Sea.

    Saturday 12th July – Day 3

    The wind has abandoned us again. Engine power once again before the westerly wind picks up to pass Gibraltar. There’s even the odd puff at 30/35 knots (55-65 km/h). We’re slaloming between cargo vessels in the strait.

    Sunday 13th July – Day 4

    Crossing the Gulf of Cadix (south-west Spain), headed for the Cape of Saint-Vincent, extreme tip of the Iberian peninsula. Very changeable head wind. We’re heading out to sea to pick up more wind.

    Monday 14th July – Day 5

    Not the right sort of weather for writing. We’re in a shaker, head to wind with strong winds and seas, 100 miles (185 km) from Cape Finisterre (north-west tip of Spain).

    Tuesday 15th July – Day 6

    Home is in sight. 320 miles (593 km) from Belle-Ile (opposite La Trinité-sur-Mer). Waiting for strong westerly winds. Looks like we’re in for a lively finish.

    Wednesday 16th July – Day 7

    The strong north-westerly forecast is here. Gitana is flying along in the middle of the night. Rattled through the last 150 miles (80 km). For one hour, we’ve had between 27 and 31 knots (50-57 km/h). Magic…Gitana. At 11h00, we dock in the harbour of La Trinité.
