ATLANTIC BOAT WORKS HIN FAQ
What does a ATLANTIC BOAT WORKS HIN look like?
It starts with the three characters "ADK" — the Manufacturer Identification Code the US Coast Guard assigned to ATLANTIC BOAT WORKS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. ATLANTIC BOAT WORKS hulls (1989–1993) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is ATLANTIC BOAT WORKS still in business?
USCG records list ATLANTIC BOAT WORKS as out of business since 1993. 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 ATLANTIC BOAT WORKS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. ATLANTIC BOAT WORKS hulls (1989–1993) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
