  • 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.

    Golf Club.

    Magdalen Islands in the middle of the Gulf of Saint Lawrence are now in the rear view mirror of both Gitana. Fred Le Peutrec (Gitana 11) is up with the leaders who are sailing within sight of each other, whereas Marc Guillemot (Gitana X) was not quite so at home in conditions which alternated from light to medium air, marked the sail down river.

    Magdalen Islands in the middle of the Gulf of Saint Lawrence are now in the rear view mirror of both Gitana. Fred Le Peutrec (Gitana 11) is up with the leaders who are sailing within sight of each other, whereas Marc Guillemot (Gitana X) was not quite so at home in conditions which alternated from light to medium air, marked the sail down river.

    The Québec-Saint Malo yacht race can be likened to a golf course… but the wrong way round ! An « approach shot » to start with down the river as far as the Pierced Rock mark, then a long shot to round the island of Saint Peter south of Newfoundland before a big « swing » over the Atlantic, followed by a « putt » in the Irish Sea and the English Channel … in order to reach the final flag at the finish in Saint Malo. A « par-four » course as it were. The Gitana Team got off to a good start in this game. Gitana 11 was part of the « famous five », in the lead at midday on Tuesday. Leaders Franck Cammas (Groupama) and Karine Fauconnier (Sergio Tacchini) are sailing shoulder to shoulder, with a group of three boat hot on their heels including Thomas Coville (Sodebo), Michel Desjoyeaux (Géant) and Fred Le Peutrec (Gitana 11) five miles astern. 36 hours into the race and the first boats have already covered 500 miles at an average speed of almost 14 knots ! Something of a surprise as the weather forecast at the start was no at all favourable. Never the less, a bit of a breeze, albeit unsteady, gave rise to accelerations of more than 25 knots and slow-gos of not quite 3 knots. Unlike the game of golf, however, the boat have to avoid falling into the holes, zones where there is no wind …  and keep sliding along  the « green » banks of the Saint Lawrence river. The situation is much clearer this morning, Tuesday, as the multihulls are finally free of the river and its pitfalls and are now sailing in the Gulf of Saint Lawrence, less effected to the tidal currents – conditions which leave the field more open to tactical shots. In a southwesterly twenty-knot breeze, they even had to tack to round Magdalen Islands in the middle of the Gulf. At lunchtime today, the first multis were at more than 25 knots of average on a direct course to the Cabot Strait and the archipelago of Saint Pierre & Miquelon which they should be passing tonight.

    On Monday evening, on Gitana X, Nicolas Raynaud described sailing on the Saint Lawrence river as « girlie weather » : « not a single wave in sight, not a drop of seaspray on the deck ! We’ll have had more than clement conditions for our sail down the Saint Lawrenc to Gaspésie, with the odd sequence of fast sailing, sometimes at speeds of 25 knots and with stretches of calm, where boatspeed came close to standstill… Which is no reason to stand there with our arms crossed. We’ve lost count of the number of gybes we have done, not to mention a short spell under the Code Zéro to negotiate a longer period of calm than is usually the case. Each of us is managing to get in a homeopathic spell of sleep, pitilessly awoken by the slightest manoeuvre. That’s the name of the game.

    A game with a slightly bitter taste for us. At the time of writing (17h00 in Québec, 23h00 French time, one mile from the coast of Gaspésie, heading for the next mark, still twenty or so miles ahead), we’re sailing with Banque Populaire slightly offset to our leeward. Since the start, we stayed with Sopra Group and Banque Covefi thanks to the one or two good tactical shots on the river – pure speed…
    An example last night, we spotted a light go whizzing past us. Faster, lower down, it was really impressive adn this boat was none other than Sodebo, which had come back into the match !
    The time to analyse this first part of the race will come when the fleet reaches the Pierced Rock… We’ve already got our fingers crossed that the guys ahead don’t whizz off ahead. On Monday evening, the wind is starting to pick up slightly ahead, blowing southerly as we are pointing our bows to the Rosiers Headland (East of Gaspésie). We roll the gennaker, hoist the Code 0 and finally continue our route under Solent jib. We hope to pass Gaspé before night fall.  »
