HILLTOP MARINE CO HIN FAQ
What does a HILLTOP MARINE CO HIN look like?

USCG records list HILLTOP MARINE CO as out of business since 1983. 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.
