The brand new Ultim from Gitana steady sports activities radical foils and rudders that showcase a really progressive method by the crew and designer Guilluame Verdier.
When the Rothschilds and Gitana crew unveil a brand new boat, they do it correctly – and final night time the large crew base in Lorient, France, turned the theatrical backdrop to the grand unveiling of Gitana 18, the extremely anticipated new foiling Ultim.
In a dramatic ‘reveal’ a silk curtain dropped mid-press convention and the gathered visitors – a few hundred media, technical companions, and the good and good of French ocean racing – realised they had been beneath some of the prime secret boat constructing initiatives of current years.
However maybe much more dramatic was the boat itself – or definitely the appendages that might be mounted to it.
The novel new foils for the Ultim Gitana 18 – the flaps on the trailing edge will be trimmed independently, whereas the arms can be lifted, and the rake adjusted.
The L-shaped foils of the present ocean-going trimarans have been changed with what the crew discuss with as ‘Y’ foils – large appendages with 5m span set on monumental swinging arms, that present a transparent lineage from the America’s Cup.
The central ‘wing’ beneath the boat is a sculptural 3m of metallic (they received’t disclose which one).
Radical rudder design
However the rudders are in contrast to something seen earlier than – an inverted ‘U’ or A-frame design. In contrast to a traditional rudder, which itself turns, the double chords of the rudder are mounted, whereas flaps on the trailing edge management path – all designed to beat the deformation that the massively loaded rudders would expertise, and apparently with no drag penalty.
The rudders of the brand new Gitana 18 are a revolutionary A-frame or ‘U’ form, with twin mounted shares or chords, however adjustable flaps.
In the meantime the rig will not be solely a canting wing mast, however is designed to bend to permit the crew to regulate the mainsail’s energy – significantly within the shift between take-off and flight, and in squally situations the place the trimaran might develop into overpowered. It’s one other component which is fully new on this scale, and is the primary Ultim mast made by Southern Spars in New Zealand.
“With this new boat, we hope to attain as near excellent flight as potential. Ideally, we’ll have the ability to fly very excessive with out ever touching the waves. We hope to have the ability to fly in 3m waves and attain a mean crusing pace bordering on 40 knots”, explains Charles Caudrelier, the skipper of the Maxi Edmond de Rothschild Gitana 18.
The crew informed me that prime pace potential is over 55 knots.
Gitana 18: designed to fly
The undertaking was designed by recognized out-of-the-box thinker Guillaume Verdier with the 30-man in-house crew at Gitana. Its major purpose is to foil for 100% of its crusing time, achieved by each lowering the wind energy at which it will possibly foil, whereas additionally sustaining larger common speeds at flight.
It builds on a lot of the information, knowledge and expertise the crew have gained from their earlier Gitana 17 (now Precise Ultim 4), which was launched eight years in the past and have become essentially the most optimised and profitable of all of the 100ft trimarans, successful the Transat Jacques Vabre, Route du Rhum, and Arkea Ultim Problem, whereas masking over 200,000 miles of ocean.

Proprietor Ariane de Rothschild additionally spoke on the launch, which she attended along with her daughters. They’re represented on the boat’s spectacular livery, designed by French inventive duo Florian and Michaël Quistrebert, in collaboration with the Palais de Tokyo. Gitana 18 is the twenty eighth boat within the Rothschild/Gitana steady, which subsequent 12 months celebrates 150 years within the sport.
“Inside my household, we’ve all the time loved a ardour for competitors, efficiency and likewise one in all technological disruption. It’s about being disruptive, figuring out the way to take dangers, gauging them and managing them. That is totally according to our philosophy,” mentioned Ariane de Rothschild.”
The Rothschild household and Gitana crew hosted a spectacular unveiling of the most recent Ultim, Gitana 18, on Wednesday 3 December.
You’ll be able to’t rush perfection, and the boat is unquestionably launching a bit of later than anticipated, however a undertaking of this magnitude will take months to work up. Its first occasion would be the 2026 Route du Rhum, which skipper Caudrelier might be trying to defend his title in, earlier than taking up solo around the globe and crewed Jules Verne document bids.
We’ll take an in-depth have a look at this unimaginable creation within the February situation of Yachting World, out January eighth.
