It's the Law: Before Going Out

Hull Identification Number

All vessels manufactured for sale must have a manufacturer's serial number or Hull Identification Number (HIN). It is unique to your vessel.

• HINs are typically engraved in the fiberglass or on a small metal plate attached to the transom.
• Record your HIN, and put it in a place away from the vessel. It can be useful if warranty problems arise or if your vessel is lost or stolen.
• If your vessel is homemade, the Department of Environmental Management will issue you an HIN and instruct you how to attach it permanently.
• It is illegal to destroy, remove, cover, or mutilate a hull identification number.
