WRIGHTSBORO SEPTIC SYS HIN FAQ
What does a WRIGHTSBORO SEPTIC SYS HIN look like?

Is WRIGHTSBORO SEPTIC SYS still in business?
USCG records list WRIGHTSBORO SEPTIC SYS as out of business since 1982. 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.
