SEA SPIRIT USA LTD HIN FAQ
What does a SEA SPIRIT USA LTD HIN look like?
It starts with the three characters "MII" — the Manufacturer Identification Code the US Coast Guard assigned to SEA SPIRIT USA LTD — followed by a 5-character hull serial and a 4-character date code, 12 characters total. SEA SPIRIT USA LTD hulls (2007–2012) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is SEA SPIRIT USA LTD still in business?
USCG records list SEA SPIRIT USA LTD as out of business since 2012. 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 SEA SPIRIT USA LTD HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. SEA SPIRIT USA LTD hulls (2007–2012) 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.
