  • 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.

    Exactly one week on from the first weather window, which was ultimately rejected, the crew of the Maxi Edmond de Rothschild has seen another departure opportunity taking shape offshore of Ushant from late in the day on Tuesday. As such, this morning, in agreement with their onshore router Marcel van Triest and Cyril Dardashti, the director of the five-arrow racing stable, Franck Cammas and Charles Caudrelier have triggered code orange among their crew and Gitana Team.

    “This looks like a promising window with a very fine passage time to the equator for the moment. The idea is to set sail from the north-west tip of Brittany once an Atlantic front has rolled through. The coming days will enable us to adjust this target window, but today we’re aiming at crossing the start line on Tuesday night through into Wednesday,” confided Charles Caudrelier.

    This information is naturally intended to be viewed simply as a possibility. Indeed, the episode last week, which saw a deterioration in the target departure window, serves as a reminder of this. In terms of weather and the record hunting, things can change very quickly in one direction or another. As a result, through until the point where the virtual start line is crossed offshore of Le Créac’h lighthouse, on the island of Ushant, the men of Gitana Team may well decide to postpone their departure and turn back. 

    “This launch window is one of the only things we can really choose in this record attempt so we’re putting in every effort to get it right. This choice has implications for the first third of the course, through until the Cape of Good Hope, which is already a very sizeable chunk. It’s a long way, as we’re talking about a forecast of over 10 days, but this does come into play in our departure criteria. We’re after optimum conditions to have a manageable departure, a quick trajectory towards the equator and then the right timing to hook onto a train of depressions in the South Atlantic. This is the sequence we’re targeting,” explained Franck Cammas.

    It’s worth noting that Gitana 17, which has been on standby in Lorient since 1 November, will be tackling her very first Jules Verne Trophy with six sailors aboard, including the two skippers of the Maxi Edmond de Rothschild. In this attempt to break the record of 40 days 23 hours and 30 minutes, held by Francis Joyon and the men of Idec Sport since 2017, Franck Cammas and Charles Caudrelier will be accompanied by Morgan Lagravière, Yann Riou, Erwan Israël and David Boileau.

    Reminder of the standby codes

    During the period of standby for the Maxi Edmond de Rothschild, which the five-arrow team has scheduled to run from 1 November to the first few days of February 2021, any changes in the situation and a possible departure date for the boat are announced via a colour coding system as detailed below:

    Black: no departure possible within 96hrs 
    Red: observation of a possible departure between 72 and 96hrs 
    Orange: observation of a possible departure between 48 and 72hrs 
    Yellow: probable departure between 24 and 48hrs 
    Green: departure within 24hrs
