  • 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.

    Discovering the innovative video system installed aboard the Mono60 Edmond de Rothschild for the Vendée Globe.

    On shore, Sébastien Josse lives like you, with his smartphone in his pocket. The skipper of the Mono60 Edmond de Rothschild will do the same at sea, during the Vendée Globe. He won’t be using it to make a call, rather to share this unique adventure. As is the case on all the latest generation boats, Gitana 16 is extremely hard to live with. As such, it was necessary to design the simplest possible device to enable the solo sailor to send images back to shore. In a bid to be as lightweight, quick and energy efficient for the skipper as possible, the boat’s iPhone 7 has become the cornerstone of an innovative video system, created within Gitana Team by Yann Riou.


    Sending photos and videos to the race organisation is compulsory within the rules of the Vendée Globe. As such, this parameter has been dealt with by Gitana Team like any other element, namely with the focus on performance. On-board ‘Reporter’ in two editions of the Volvo Ocean Race (crewed round the world race with stopovers) and, last winter, in the Jules Verne Trophy record attempt, Yann Riou joined the five-arrow team in the spring of 2016, with the main aim of designing the best possible on-board video solution for Sébastien Josse with a view to the Vendée Globe.

    “This generation of boats has reached such a high level of performance that it’s becoming complicated, impossible even, to find places on deck where you can safely work and shoot,” he explains. “I’ve been lucky enough to sail on a whole host of different boats, Volvos, multihulls… I’ve never seen anything like this. Never before have I faced such obstacles in the way I approach a shoot.”

    Once the observation was made, it was deemed necessary to find solutions for getting around the problem.

    “Aboard Edmond de Rothschild, I have a very simple system that operates with a smartphone and Wi-Fi,” explains Sébastien Josse, who’s very open-minded when it comes to fine tuning new ideas geared towards being competitive. “I can make videos with an iPhone and all I have to do is turn on the satellite dish to send them! It couldn’t be simpler to use but it was a real technical challenge to fine-tune this solution in such a short space of time.”

    Live and recorded, four cameras controlled from the iPhone

    Two fixed cameras have been installed aboard Edmond de Rothschild. With wide angle lenses, one looking forward and the other towards the cockpit and the wake. They can even be used in rough weather and from down below if Sébastien has to stay sheltered. The skipper can also film and film himself with the two iPhone 7 cameras; a device that is waterproof.

    Beyond the simplicity of having a smartphone in the pocket of your foulies so as to film or photograph what you want, when you want, the benefit of this solution is not having to carry a ‘media’ computer on the boat. Indeed, prior to this innovation, it was necessary to have a dedicated device on which to upload images, crudely edit them and then send them back to shore. That took time of course, but it also added a fair amount of weight as the skippers preferred to have a dedicated computer aboard so as to avoid any conflicts with the navigation software.

    ‘Custom’ app

    In terms of applications, Gitana Team has sometimes opted to combine solutions that are available commercially and ‘customised’ systems developed by Ektacom. The latter company specialises in video solutions and worked in collaboration with Gitana Team in this process. They notably designed and installed the elements that manage the different cameras and above all created an application for the ‘live’ footage. When Sébastien wants to be live on television, on the web, and on the social networks, he’ll use an application reminiscent of FaceTime but geared around the constraints of the satellite link.

    Indeed, despite the progress of technology, an Internet connection is always low speed aboard: 256 kilobits, or less than a first generation ADSL… When they’re in the Deep South, far from the commercial shipping lanes, the competitors will also traverse vast deserts of satellite coverage.

    A drone of course!

    Finally, in light to medium weather systems, the skipper of Gitana 16 can try to take us to new heights mid-ocean by getting his drone airborne. Here too, it’s a simple model, sold commercially, which has taken up position aboard the Mono60 Edmond de Rothschild. “It’s also an alternative to the demanding boat shots that enables the skipper to film what’s happening and the environment at a given time. We film around the boat with the drone, which creates some rather nice images,” Yann Riou continues. “With this in mind, Sébastien has trained himself to operate the drone. However, it’s not the same thing to use these machines when racing, singlehanded, as it is when you’re training in crewed configuration around Lorient…”
