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—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.
Owners of homemade vessels must obtain an HIN from the Alaska DMV.
It is illegal to deface, alter, remove, or destroy an HIN.
