THIRD COAST COMPOSITES HIN FAQ
What does a THIRD COAST COMPOSITES HIN look like?
It starts with the three characters "THD" — the Manufacturer Identification Code the US Coast Guard assigned to THIRD COAST COMPOSITES — followed by a 5-character hull serial and a 4-character date code, 12 characters total. THIRD COAST COMPOSITES hulls (2009–2016) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is THIRD COAST COMPOSITES still in business?
USCG records list THIRD COAST COMPOSITES as out of business since 2016. 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 THIRD COAST COMPOSITES HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. THIRD COAST COMPOSITES hulls (2009–2016) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
