COLORADO COMPOSITES INC HIN FAQ

Is COLORADO COMPOSITES INC still in business?
USCG records list COLORADO COMPOSITES 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.
