J & J FIBERGLASS HIN FAQ
What does a J & J FIBERGLASS HIN look like?

Is J & J FIBERGLASS still in business?
USCG records list J & J FIBERGLASS as out of business since 1990. 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.
