T & T SHIP SHAPERS HIN FAQ
What does a T & T SHIP SHAPERS HIN look like?

USCG records list T & T SHIP SHAPERS 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.
