FIBERGLASS SPECL UNLTD HIN FAQ
What does a FIBERGLASS SPECL UNLTD HIN look like?
It starts with the three characters "FXU" — the Manufacturer Identification Code the US Coast Guard assigned to FIBERGLASS SPECL UNLTD — followed by a 5-character hull serial and a 4-character date code, 12 characters total. FIBERGLASS SPECL UNLTD hulls (1978–1983) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984.
Is FIBERGLASS SPECL UNLTD still in business?
USCG records list FIBERGLASS SPECL UNLTD as out of business since 1983. 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 FIBERGLASS SPECL UNLTD HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. FIBERGLASS SPECL UNLTD hulls (1978–1983) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
