SEAGO ENTERPRISES INC HIN FAQ
What does a SEAGO ENTERPRISES INC HIN look like?

Is SEAGO ENTERPRISES INC still in business?
USCG records list SEAGO ENTERPRISES INC as out of business since 1992. 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.

On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. SEAGO ENTERPRISES INC hulls (1991–1992) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
