Course Outline

The Hull Identification Number (HIN) is a unique 12-digit number assigned by the manufacturer to vessels built after 1972.

These numbers:

  • Distinguish one vessel from another—the same as serial numbers distinguish one car 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.
