EXCEL MARINE HIN FAQ
What does a EXCEL MARINE HIN look like?
It starts with the three characters "XLL" — the Manufacturer Identification Code the US Coast Guard assigned to EXCEL MARINE — followed by a 5-character hull serial and a 4-character date code, 12 characters total. EXCEL MARINE built hulls across both HIN eras (1972–1992): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format.

Is EXCEL MARINE still in business?
USCG records list EXCEL MARINE as out of business since 1992 (associated with GENMAR). 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 EXCEL MARINE HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year.
