Our story

Guelt, the mother company with its roots in the manufacturing of equipments for the technically-demanding agrifood industry, founded Guelt Nautic more than 20 years ago to apply its mature expertise in precision metalwork for applications in another challenging market: performance sailing.

Established between the ocean racing centres of Lorient and Pors-la-Forêt in South Brittany, Guelt Nautic has become a major company for design, manufacturing and refit of complex mechanical and high technological parts for ocean racing and yachting industries.

Thanks to its important production facility and its complementary skills (engineering, metalworks, mechanics, electrics, automation),
Guelt Nautic is able to respond with expertise and reactiveness to dimensioned and technically demanding projects.

Our philosophy

Driven by innovation, competition and challenge, our teams of technicians take on the challenges of the sailing world.

Our great knowledge of the boating industry and its constraints allows us to respond quickly and effectively to requests from skippers and their teams.
