Check with the local authorities. i'm sure there are better informed on this. but the auth. can do an ownership trace basid upon last knowen registration. then either you can try to contact the owner, or the city may have already placed a lien on the boat and then its just a bunch of paperwork. from what little I know, salvage rights wouldn't apply. Its an abondoned property issue. and the owner of the land needs to place a lien on it. any lawyers outthere let us know
