COMMON SENSE DESIGNS LLC HIN FAQ
What does a COMMON SENSE DESIGNS LLC HIN look like?
It starts with the three characters "EJY" — the Manufacturer Identification Code the US Coast Guard assigned to COMMON SENSE DESIGNS LLC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. COMMON SENSE DESIGNS LLC hulls (1997–2001) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is COMMON SENSE DESIGNS LLC still in business?
USCG records list COMMON SENSE DESIGNS LLC as out of business since 2001. 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 COMMON SENSE DESIGNS LLC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. COMMON SENSE DESIGNS LLC hulls (1997–2001) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
