SUNLINER MFG CO INC HIN FAQ
What does a SUNLINER MFG CO INC HIN look like?

Is SUNLINER MFG CO INC still in business?
USCG records list SUNLINER MFG CO INC as out of business since 1981. 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.
