Hull Serial Number ( HIN )
All pleasure craft manufactured in Canada, or imported into Canada, after August 1, 1981 shall be permanently marked with a Hull Serial Number (HIN). No person should remove, alter or otherwise tamper with a HIN. The 12 digit HIN identifies when the vessel was built and by whom, and is often used to help identify lost or stolen vessels.
The HIN can be found on the outboard starboard side of the transom (see image below).
