Nautical Consulting

Of special interest and care for our office are issues concerning the vessel itself.

We are devoted to the documentation process for registration and flagging of vessels; boat purchase contracts; property changes; engine changes; list changes; entry in the Registry of Personal Property and any and all aspects of procedure for vessels. We also process navigation permits for rental purposes throughout the Balearic archipelago.
