Hull Identification Number


The Hull Identification Number (HIN) is a unique 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.
