About the USCG HIN format

Coastal Marine Boat Works is registered with the US Coast Guard and stamps a standard 12-character Hull Identification Number on every vessel produced for the US market. The format breaks down as:

GDQ NNNNN M Y YY
└┬┘ └──┬──┘ │ │ └┬┘
 │    │     │ │  └─ Model year (last two digits)
 │    │     │ └──── Production year (last digit, 1972 standard)
 │    │     └────── Production month (A=Jan, B=Feb ... L=Dec, skipping I)
 │    └──────────── Hull serial number (alphanumeric)
 └─────────────── MIC: Manufacturer Identifier Code (GDQ)

Federal regulation 33 CFR § 181 requires every US-built or imported recreational vessel to display this HIN permanently on the upper starboard side of the transom, and a duplicate HIN in a hidden location inside the hull.
