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 a HIN from the Alaska DMV.
It is illegal to deface, alter, remove, or destroy a HIN.
