How Do I Contact My Boat Manufacturer to Get a Hull Identification Number (HIN)?
A HIN is required for boats manufactured after November 1, 1972. If the HIN is unavailable and unknown, the boat owner must first contact the boat manufacturer to obtain a replacement HIN. The U.S. Coast Guard maintains a list of boat manufacturers and contact information at this external web site.
If the manufacturer is out of business or will not assist the boat owner, a DNR HIN Inspection is necessary. DNR will assign a HIN number during the inspection process and the boat owner is responsible for permanently affixing the HIN to the boat.
