WM KAIER FIBERGLAS PRO HIN FAQ
What does a WM KAIER FIBERGLAS PRO HIN look like?
It starts with the three characters "WKF" — the Manufacturer Identification Code the US Coast Guard assigned to WM KAIER FIBERGLAS PRO — followed by a 5-character hull serial and a 4-character date code, 12 characters total.

Is WM KAIER FIBERGLAS PRO still in business?
USCG records list WM KAIER FIBERGLAS PRO as out of business since 1980. 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 WM KAIER FIBERGLAS PRO HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year.
