Our skills

The reconstruction of the Hermione has been a real challenge for Asselin and Yacht Concept: beyond their own skills and know-how, they were able to develop a perfect synergy and find truly innovative solutions to complete the project, which in turn helped develop their respective businesses, considering the high level of skill required and the challenge in R & D.

Both companies have wished to pursue this exemplary cooperation and bring their complementarity and their values together in a common structure.

Thus the Chantier de l’Arsenal was born, a shipyard that successfully associates technological research, engineering and project management in the field of yachting with the most prestigious woodwork.
