The barge I am buying was a USCG registered boat. I am simply going to transfer ownership, retain the boats name, etc. If I understand correctly (always questionable) I have to change the "port of call" on the boat. Not a problem but my question is, do I then need to "register" the boat in the state where the port of call is? I see there is no license decal currently on the boats bow. Any help is appreciated.
