What is a hull identification number?
A hull identification number (or HIN) means a number assigned to specific watercraft by the manufacturer or by a government jurisdiction as prescribed by the U.S. Coast Guard. It is similar to a car’s vehicle identification number. All watercraft manufactured after August 1972 are required by federal law to have a 12 digit HIN. your watercraft will require inspection if it is homemade or newer than the 1972 and does not have a conforming HIN number.
