INTERNATIONAL YACHT BLDRS LTD HIN FAQ
What does a INTERNATIONAL YACHT BLDRS LTD HIN look like?

USCG records list INTERNATIONAL YACHT BLDRS LTD as out of business since 1992. 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.
