Boats on sea

Maximum length (m)

Surface shipyard (m²)


The shipyard, based in Gujan-Mestras, on the Bassin d’Arcachon near Bordeaux, houses all the premises for the study and production of ships. This includes: the design and engineering office, the research and development department as well as all the production workshops. Luxury yachts and defence vessels are therefore entirely created, developed and built in house.

The Bassin d’Arcachon is an exceptional place, similar to a landlocked sea. It offers a unique test base for boats. No port within 160 km to the north or south: a changing narrow path to enter the bay, making entry and exit navigation very dangerous, ideal for developing and testing boats before confronting them with difficult sailing conditions.
