The project's institutional partners provided support as of the 2000 campaign – support that was renewed each year thereafter.
Thus, every year, the Ministry of Culture and Communication and the local authorities allowed the Adramar association to ensure the financial supervision of the project, and to recruit staff members.
The financial partners of the excavation project:
- The Ministry of Culture and Communication, General Directorate for Heritage, Sub-Directorate for Archaeology, Directorate for Underwater Archaeological Research (Drassm)
- The Brittany Region
- The département of Ille-et-Vilaine
- The Saint-Malo municipal authorities
