US YACHTS HIN FAQ
What does a US YACHTS HIN look like?
It starts with the three characters "USY" — the Manufacturer Identification Code the US Coast Guard assigned to US YACHTS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. US YACHTS hulls (1982–1983) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984.
Is US YACHTS still in business?
USCG records list US YACHTS as out of business since 1983 (associated with BRUNSWICK MARINE). 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 US YACHTS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. US YACHTS hulls (1982–1983) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
