It's the Law: Before Going Out

Hull Identification Number

The Hull Identification Number (HIN) is a unique, 12-digit or 17-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.

It is illegal to destroy, remove, alter, or deface a Hull Identification Number.
