GROUPE BENETEAU, the world leader in the manufacture of cruising boats, has entrusted MULTIPLAST GROUPE CARBOMAN to build the foils for its new monotype in the Figaro Class.

In the summer of 2016, Bénéteau Group launched a global tender call to find a subcontractor able to produce the foils for its new cruising monotype designed by VPLP. The goal was ambitious, because the selected yard will have to produce two foils per week for one year, scrupulously respecting both the monotype design and in a strict economic framework.
Selected a few days before the 2016 Nautic, the knowledge of the company from Vannes, not least the technologies used in wind power by Plastinov (closed mould, resin infusion, etc.), enabled Multiplast to take up the challenge.
Samuel Napoléoni, engineer in charge of the project at Multiplast explains : "A first mould section of about 500 mm was quickly machined in order to carry out the process of validation tests. Each test took a week, we ran the process for a fortnight in order to work any "bugs" out of the construction procedure. At the beginning of the year, our objective was to make the manufacturing process strong enough to start mass production. In parallel, we produced the moulds and worked on the ergonomics of the workstation. It provided great satisfaction when at the end of June we took out the first four foils. At that time, we knew that we were on the right path."
It was at 5AM Monday morning (17/07) that Multiplast's assembly hall doors finally opened to allow the launch of the Maxi trimaran Edmond de Rothschild. At 32 metres long and 23 metres wide, the boat, suspended by a crane 10 metres up, didn't go unnoticed...
Multiplast teams had the opportunity to build a boat that was highly refined in its design. The Gitana design team and Guillaume Verdier have, in particular, developed the flight capabilities, the optimisation of the composite structure, the control systems and the reduction of the aerodynamic drag of this multihull. This giant is the first ocean trimaran designed specifically to navigate completly on its foils, rudders and center board. Until now, these appendages served only to relieve the platform; today, a new threshold in boat design has been crossed.
In terms of innovation, for the first time, Multiplast had the opportunity to produce the maxi multihull arms in the giant autoclave at the Airbus plant in Nantes. Asked by Guillaume Verdier, the architect, Multiplast's links with the world of aeronautics made possible to propose to Gitana the processes and industrial methods usually reserved for the manufacture of the Airbus A350.
20 months to build
The Maxi trimaran Edmond de Rothschild was born thanks to the close cooperation between the client and the teams at the construction site in Vannes. In total some 170,000 hours of work were required to carry out the build for this 20-month project. For the 70 Multiplast employees, divided into eight teams, this project represented some 96 000 hours of work (excluding the toolings)
Carboman Group (Carboman) the market leading group specializing in development, prototyping and the manufacturing of high-end composite structures, today announced that it is collaborating with Eviation Aircraft, a global manufacturer of all-electric air mobility solutions, on Eviation’s Alice - an all-electric aircraft structure that will debut at the 53rd Paris Air Show in Le Bourget.
