L=Dec, skipping I) │ └──────────── Hull serial number (alphanumeric) └─────────────── MIC: Manufacturer Identifier Code (GEM)
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.
