NORTHERN WATERS IND LTD HIN FAQ

NORTHERN WATERS IND LTD hulls (2005–2013) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is NORTHERN WATERS IND LTD still in business?
USCG records list NORTHERN WATERS IND LTD as out of business since 2013. 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.
