If you need to find out who is on the title for a boat, you will need to gather certain identifying information from the vessel. In instances where you have been in a boating accident and the other boater sped away, you may be able to identify the boat by its name and port of hail. Keep in mind that many jurisdictions do not disclose title information about boat owners in order to protect people's privacy, but if you have an accident report or a pending lawsuit where the information is privy to discovery, you may be entitled to the information.
