SUNSET INC HIN FAQ

What does a SUNSET INC HIN look like?

It starts with the three characters "SUU" — the Manufacturer Identification Code the US Coast Guard assigned to SUNSET INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. SUNSET INC hulls (1992–1994) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.

Is SUNSET INC still in business?

USCG records list SUNSET INC as out of business since 1994. 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 SUNSET INC HIN?

On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. SUNSET INC hulls (1992–1994) 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.
