RFD PATTEN HIN FAQ
What does a RFD PATTEN HIN look like?
It starts with the three characters "RFF" — the Manufacturer Identification Code the US Coast Guard assigned to RFD PATTEN — followed by a 5-character hull serial and a 4-character date code, 12 characters total. RFD PATTEN hulls (1979–1983) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984.
Is RFD PATTEN still in business?
USCG records list RFD PATTEN as out of business since 1983. 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 RFD PATTEN HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. RFD PATTEN hulls (1979–1983) 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.
