Marine engineering has been our business since 1995, and classic yachts, our speciality.

The refined decoration and the precious materials found in classic yachts require specific expertise and a great deal more. The captains of these ships expect more than a trade from us, true passion is called for.

Accurate handling of heavy, oversized parts, carpentry and joinery work that is respectful of the age of the structures and materials and the quality of the finishes, refitting engines by taking account of the lack of available space and the ship’s elegant style...

A recognized expertise

When carrying out maintenance or repair, we know that we have to reconcile the irreconcilable. And, as more often than not, there is only one propulsion engine on-board, it must be totally reliable. Over 20 years, by combining technical expertise with responsiveness, BSM has built a sold reputation, leading it to work on iconic boats such as Altair, Amadour, Agneta, Rowdy, Puritan, Thendara, Seaway, Moon Beam III and Chinook, to name but a few.

High quality services

In 25 years, BSM has earned the trust of renowned professionals.

The Pasqui boatyard in Villefranche-sur-mer, the refit yard for classic boats, asked BSM to handle the engineering parts of its projects. Similarly, BSM handles the maintenance and refitting of engines and generators for Nautor Swan, the Mediterranean maintenance base for Swan yachts.
