It's the Law: Before Going Out on Your Vessel

Hull Identification Number (625 ILCS 45/3-13)

All vessels built after November 1, 1972, including home-made boats, must have a Hull Identification Number (HIN). The HIN is unique to your vessel. It is required by federal law and must appear on the registration application. HINs are typically engraved in the fiberglass or on a small metal plate attached to the transom. If a vessel has no HIN, or if it has been removed, obliterated, or altered, the owner must apply to the Department of Natural Resources for a HIN.
