CLEMAR MFG INC HIN FAQ
What does a CLEMAR MFG INC HIN look like?
It starts with the three characters "DHT" — the Manufacturer Identification Code the US Coast Guard assigned to CLEMAR MFG INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. CLEMAR MFG INC hulls (1989–2003) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is CLEMAR MFG INC still in business?
USCG records list CLEMAR MFG INC as out of business since 2003. 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 CLEMAR MFG INC HIN?
