FINISH LINE ENGINEERNG HIN FAQ

What does a FINISH LINE ENGINEERNG HIN look like?

It starts with the three characters "FNI" — the Manufacturer Identification Code the US Coast Guard assigned to FINISH LINE ENGINEERNG — followed by a 5-character hull serial and a 4-character date code, 12 characters total. FINISH LINE ENGINEERNG 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.

Is FINISH LINE ENGINEERNG still in business?

USCG records list FINISH LINE ENGINEERNG of LAKE HAVASU CITY, AZ in the MIC database (registered 1985).

How do I decode the year on a FINISH LINE ENGINEERNG HIN?

On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. FINISH LINE ENGINEERNG 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. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.

Where is the HIN on a FINISH LINE ENGINEERNG 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 "FNI" MIC the same as a FINISH LINE ENGINEERNG serial number?

No. "FNI" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies FINISH LINE ENGINEERNG. The hull serial number is characters 4–8: FINISH LINE ENGINEERNG'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 FINISH LINE ENGINEERNG 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 FINISH LINE ENGINEERNG records, the title, or a marine survey to confirm the exact model and configuration.
