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. They are engraved or stamped in the hull transom, on a metal plate attached to the transom, or printed on inflated rafts and kayaks.
• Record the HIN and put in a place other than the vessel in case warranty problems arise or the vessel is lost or stolen.
• If your vessel is homemade, the Department of Natural Resources may issue you a HIN, which you then must affix permanently to the transom.
• It is illegal to destroy, remove, cover, or mutilate a HIN.
