SISU ENTERPRISES INC HIN FAQ
What does a SISU ENTERPRISES INC HIN look like?
It starts with the three characters "SIU" — the Manufacturer Identification Code the US Coast Guard assigned to SISU ENTERPRISES INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. SISU ENTERPRISES INC hulls (2012–2012) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is SISU ENTERPRISES INC still in business?
USCG records list SISU ENTERPRISES INC as out of business since 2012. 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 SISU ENTERPRISES INC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. SISU ENTERPRISES INC hulls (2012–2012) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
