SEAMASTER BOATS HIN FAQ
What does a SEAMASTER BOATS HIN look like?
It starts with the three characters "VFH" — the Manufacturer Identification Code the US Coast Guard assigned to SEAMASTER BOATS — followed by a 5-character hull serial and a 4-character date code, 12 characters total.

USCG records list SEAMASTER BOATS as out of business since 1985. 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.
