Vessel reference
Every boat built in the United States since 1972 carries a Hull Identification Number, and the first three characters are the Manufacturer Identifier Code (MIC) — assigned under 33 CFR Part 181 and recorded in a database of roughly 16,000 builders. Browse the directory by letter, or decode a full HIN to identify a specific boat’s maker and model year.
A Manufacturer Identifier Code is a unique three-character code the U.S. Coast Guard assigns to each boat builder. It is the leading segment of the 12-character HIN — for example, a HIN beginning BUJ identifies one specific manufacturer. Codes are retained even after a company goes out of business, which is why an older boat’s MIC can still be looked up here.
Enter a 12-character HIN to identify the builder, model year, and documented sister ships.
