YUKON DELTA HIN FAQ
What does a YUKON DELTA HIN look like?

Is YUKON DELTA still in business?
USCG records list YUKON DELTA as out of business since 2001. 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.
