What does a ELEVENTH COAST GUARD DISTRICT HIN look like?

USCG records list ELEVENTH COAST GUARD DISTRICT as out of business since 1995. 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.
