UNITED MARINE INTERNATL LLC HIN FAQ
What does a UNITED MARINE INTERNATL LLC HIN look like?
It starts with the three characters "UMB" — the Manufacturer Identification Code the US Coast Guard assigned to UNITED MARINE INTERNATL LLC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. UNITED MARINE INTERNATL LLC hulls (1996–2003) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is UNITED MARINE INTERNATL LLC still in business?
USCG records list UNITED MARINE INTERNATL LLC as out of business since 2003 (associated with ELLICOTT CORP). That's common for older hulls — the HIN still decodes normally, and the out-of-business date helps date the boat and guides parts-hunting toward salvage and owner groups rather than a dealer network.
How do I decode the year on a UNITED MARINE INTERNATL LLC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. UNITED MARINE INTERNATL LLC hulls (1996–2003) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
