SHOESTRING SHIPYARD HIN FAQ
What does a SHOESTRING SHIPYARD HIN look like?
It starts with the three characters "WXI" — the Manufacturer Identification Code the US Coast Guard assigned to SHOESTRING SHIPYARD — followed by a 5-character hull serial and a 4-character date code, 12 characters total. SHOESTRING SHIPYARD hulls (1997–2013) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is SHOESTRING SHIPYARD still in business?
USCG records list SHOESTRING SHIPYARD as out of business since 2013. 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.
How do I decode the year on a SHOESTRING SHIPYARD HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. SHOESTRING SHIPYARD hulls (1997–2013) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
