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.
  • Are engraved in the fiberglass or on a metal plate permanently attached to the transom.
• You should write down your HIN and put it in a place separate from your vessel in case warranty problems arise or your vessel is stolen.
• If your vessel is homemade, the Department of Environmental Management will issue an HIN for your vessel and instruct you how to attach it permanently.
• It is illegal to destroy, remove, cover, or mutilate a hull identification number.
