RO-MAR USA INC HIN FAQ
What does a RO-MAR USA INC HIN look like?

USCG records list RO-MAR USA INC as out of business since 2003. 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.
