What is a HIN?
A Hull Identification Number (HIN) is a 12-character code that identifies a boat or personal watercraft, much like a VIN identifies a car. The PPSR records security interests in boats and jet skis against the HIN.
Where to find the HIN
On most boats the HIN is on the top right of the transom (the flat back of the hull), on the starboard side. On jet skis it’s usually at the rear of the hull. It should match the HIN on the boat’s registration papers.
Checking the trailer too? A boat trailer is a separate item with its own VIN or chassis number, and it can have its own finance. Check the trailer separately.
Why check a used boat?
- Finance owing. Boats are often bought on finance. An unpaid loan can stay attached to the boat after it’s sold.
- Theft. Boats, jet skis and outboards are regularly stolen from driveways and marinas.
- Mismatched paperwork. The HIN on the hull, the registration and the seller’s ID should all line up.
Inspection tips
- Check the hull for cracks, soft spots and repairs, especially around the transom.
- Ask for engine hours and service records, and have the motor checked by a marine mechanic.
- Check the outboard’s serial number against the paperwork.
- Confirm what’s included in the sale: trailer, electronics, safety gear.
