AMERICAN SHOALDRAFT SAILBOAT HIN FAQ
What does a AMERICAN SHOALDRAFT SAILBOAT HIN look like?

USCG records list AMERICAN SHOALDRAFT SAILBOAT as out of business since 1989. 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 AMERICAN SHOALDRAFT SAILBOAT HIN?
