It's the Law: Before Going Out

Hull Identification Number

The Hull Identification Number (HIN) is a unique, 12-digit number assigned by the manufacturer to vessels built after 1972. Hull Identification Numbers distinguish one vessel from another and are engraved in the fiberglass or on a metal plate attached to the transom. If the HIN is missing or nonexistent, such as with a home-built vessel, apply to the MDOR for an identification number.
