Transferring Vessel Flags Between Spain and Italy: Step-by-Step
Nautelo editorial team · September 26, 2026

How to deregister a vessel in one registry and register it in the other without losing months.
Moving a boat between the Spanish and Italian registries is a two-sided process: the old flag must release the vessel before the new one can register it.
Start by requesting the certificate of deregistration from the current registry, and confirm that no liens or charter registrations are outstanding. Next, gather the bill of sale, proof of VAT status and the builder's declaration of conformity.
Finally, file the registration in the new flag state and update your insurer. Allow several weeks and involve a nautical legal adviser early.
