Mono60 Edmond de Rothschild
Belonging to the IMOCA class, the Mono60 Edmond de Rothschild was launched in August 2015 after a year-long build at the Multiplast yard. This Verdier design with her planing forms is a latest generation 60-foot monohull designed with a view to the Vendée Globe 2016 - 2017.

Since its creation, the Gitana Team has constantly explored the multiple thrilling aspects of multihulls. However, in its fifteen-year history, a few monohulls have managed to make a niche for themselves within the Gitana fleet. An agreed ‘bending of the rules’ for the beauty of the race we nickname the Everest of the Seas and the sporting and human challenge that it represents: the Vendée Globe.
In this way, eight years after Gitana Eighty, the Mono60 Edmond de Rothschild, alias Gitana 16, makes her entrance into the legendary Gitana Saga. And the very least that can be said is that the boat is sleek in her styling: planing hull equipped with a very high volume bow to enhance the boat’s speed performance, a so-called tumblehome hull shape (meaning that the beam at the sheer is less than the maximum beam of the hull) so as to limit the beam of the deck and thus make her more lightweight, reduction of the freeboard, which further accentuates the sensation of the boat’s beaminess, a flat deck and open cockpit, not to mention foils instead of the old generation conventional daggerboards… Gitana 16 certainly doesn’t lack character.
Adhering to the new class measurement in force in the Imoca class since December 2013, the Mono60 Edmond de Rothschild will be equipped with a one-design keel and mast (identical materials, forms and suppliers). These rules, voted in at the end of the last Vendée Globe so as to increase the safety coefficients and reduce the costs of these incredible machines.
The Vendée Globe for goal
The third boat from the new generation (the 5th already!) to come out of its ‘box’, the Mono60 Edmond de Rothschild is the fruit of collective work! Keen not to take any chances whilst retaining its singularity, the Gitana Team formed an in-house design office made up of Antoine Koch, Armand de Jacquelot and Sébastien Sainson, whilst the technical monitoring of the build was entrusted to Pierre Tissier. This quartet worked in close collaboration with the project’s naval architects - Guillaume Verdier and Daniele Capua at VPLP Yacht Design – and Yann Penfornis’ teams at Multiplast. From this collaboration a latest generation 60-foot monohull has seen the light of day, equipped with lifting surfaces that meet both the expectations and the requirements of Sébastien Josse: solidity, reliability and ergonomics.
The architectural particularities
Aerodynamic roof and mast foot bowl
to lower the rig
Open aft section
to facilitate stacking
Recentered and lowered cockpit
More high volume
to increase the boat’s power
with lifting surfaces (foils)
The foil, how does it work?
This is one of the major new features of this 5th generation Imoca monohull. Since their arrival on the scene the foils have caused a lot of ink to flow and unleashed great passion. Indeed, there are both supporters and opponents of these new appendages, whose very shape is reminiscent of the moustaches of a famous Spanish painter. An unquestionable architectural development, foils are nonetheless a daring challenge for those who have opted to equip their steed with such a device.
Principles and actions
The cockpit in detail
At first sight, the cockpit of the Mono60 Edmond de Rothschild is certainly eye-catching. The watchwords that have guided her design are safety and ergonomics, which go together with performance. We take an in-depth guided tour with Sébastien Josse.
Very open like the VORs of the Volvo Ocean Race
The mainsheet traveller on the Mono60 Edmond de Rothschild is attached to the sole whilst on the rivals’ boats it forms an arch, which closes off the back of the boat around 80cm above the ‘sole’ at deck level. This improved configuration provides an optimised workspace and a stacking zone aft that is within shoulder width, without having to clamber over the imposing sail bags on deck.
The lower the centre of gravity, the less energy a boat needs to move around and the more stable it is. With this in mind, we sought to lower the centre of gravity as much as possible. The upshot of this was the footwell area in the sole beneath the cuddy. Not only did it enable us to lower the latter and hence improve the aerodynamics, but also to do the same thing with the deck hardware, the pit chute and the other structural elements in this zone, at the crux of which was a significant weight saving. Similarly, the decision was taken to make a central chute for the pit so as to favour the boat’s fore and aft axis (bow - keel - transom).The final benefit of this footwell area: we retain a significant height under the cuddy, which will enable me to manoeuvre in the upright position rather than hunched up like my rivals. Down below, it’s fairly uncluttered. There are no frills but I’m leaving myself the time to develop the fit-out prior to the start of the Vendée Globe.
The fact that the cockpit sole is very low enables guardrails at chest height, whilst on deck these are knee-level. This configuration is a safety element, particularly in bad weather and heavy seas.
