About the USCG HIN format
Blue Seas 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:
QQB 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 (QQB)
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.
