ALUMINUM CHAMBERED BOATS HIN FAQ
What does a ALUMINUM CHAMBERED BOATS HIN look like?
It starts with the three characters "SBK" — the Manufacturer Identification Code the US Coast Guard assigned to ALUMINUM CHAMBERED BOATS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. ALUMINUM CHAMBERED BOATS hulls (1999–2011) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is ALUMINUM CHAMBERED BOATS still in business?
USCG records list ALUMINUM CHAMBERED BOATS as out of business since 2011. 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 ALUMINUM CHAMBERED BOATS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. ALUMINUM CHAMBERED BOATS hulls (1999–2011) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
