RIDALCO SPECIALTY METAL PROD HIN FAQ
What does a RIDALCO SPECIALTY METAL PROD HIN look like?
It starts with the three characters "ZRX" — the Manufacturer Identification Code the US Coast Guard assigned to RIDALCO SPECIALTY METAL PROD — followed by a 5-character hull serial and a 4-character date code, 12 characters total. RIDALCO SPECIALTY METAL PROD hulls (1985–present) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.

How do I decode the year on a RIDALCO SPECIALTY METAL PROD HIN?

Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
Where is the HIN on a RIDALCO SPECIALTY METAL PROD boat?
On the outside upper-starboard (right) corner of the transom, within two inches of the top — required by 33 CFR 181.29. Since August 1984 an identical duplicate HIN is also molded into an unexposed interior location as an anti-theft measure. Both should match the title, registration, and insurance card exactly.
Is the "ZRX" MIC the same as a RIDALCO SPECIALTY METAL PROD serial number?
No. "ZRX" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies RIDALCO SPECIALTY METAL PROD. The hull serial number is characters 4–8: RIDALCO SPECIALTY METAL PROD's own production number for that specific boat (the letters I, O, and Q are never used). The full 12-character HIN combines the MIC, the serial, and the date code.
Can a RIDALCO SPECIALTY METAL PROD HIN tell me the exact model?
Not on its own. A HIN encodes the builder, hull serial, certification month/year, and model year — not the model name or length. Match the decoded year and serial against RIDALCO SPECIALTY METAL PROD records, the title, or a marine survey to confirm the exact model and configuration.
