The idea first came in the 80s when we were designing big competition trimarans that we gave reduced-size outriggers and associated foils.
The boat industry has been at a standstill has for some thirty years - with no real development except for container carriers. We believe that in applying a whole set of technological innovations one could build a truly revolutionary vessel. Our concept involves incorporating new machinery like Rolls Royce hydrojets, which were designed for big ships, and the range of new alloys currently available, like Sealium produced by the Pechiney company - components that are perfectly suited to new speed performances and demanding sea-keeping requirements.

As of 1983, and concurrently with designing monohull racers, Gilles Vaton developed his first racing trimarans. They had the following innovative features:
- slender, planing hull
- vertical wave-piercing bow
- ground-effect from the wing-arms, arched and profiled in aeronautic fashion
- foils fitted to the outriggers
- wing-shaped mast with wind-activated swivelling (taken up again recently on the best ORMA multihulls)
The giant 26-metre foiler-trimaran Charles Heidseick IV inaugurated the concept,
followed in 1985 by the foiler PACA , its staggering performances confirming the
excellence of the project.

The way was open for an initial project for a BGV-type high-speed ferry. Its design in 1986-87 was the veritable starting point of this revolutionary concept applied to maritime transport.
The design documents and patent applications were filed at the end of the 80s and allowed studies of successive projects to be developed in close symbiosis with the way the market was rapidly developing.

There followed a first session of tank testing (DCN, 1999-2000) and the design work on the first range of fast ferries.

On its heels came design work on a set of military and freight applications that broadened the applications of the concept and demonstrated its wide-ranging possibilities.

At the present time concept application is targeted especially at the largest vessels, pushing their performance potential ever higher - performance predictions confirmed by extensive tank testing programmes.

81% of the world's freight is maritime yet the sole technological development at the end of the 20th century was the appearance of container carriers!
Europe's continental road and rail traffic is nearing suffocation point and the concept of mixed transportation using "sea highways" has come to the fore.
Rapid maritime transportation of passengers and vehicles is a market of the future that is as yet poorly exploited; inefficient optional solutions persist at a time when energy-saving and pollution concern are key factors.
Maritime transportation is competitive, especially where vessels provide the necessary improved speeds and reliability that can guarantee efficient operation in even severe weather conditions.
