HYFOIL MARINE (DBA) HIN FAQ

What does a HYFOIL MARINE (DBA) HIN look like?

It starts with the three characters "HYM" — the Manufacturer Identification Code the US Coast Guard assigned to HYFOIL MARINE (DBA) — followed by a 5-character hull serial and a 4-character date code, 12 characters total. HYFOIL MARINE (DBA) hulls (2019–present) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.

Is HYFOIL MARINE (DBA) still in business?

USCG records list HYFOIL MARINE (DBA) of ARMONK, NY in the MIC database (registered 2019).

How do I decode the year on a HYFOIL MARINE (DBA) HIN?

On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. HYFOIL MARINE (DBA) hulls (2019–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 HYFOIL MARINE (DBA) 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 "HYM" MIC the same as a HYFOIL MARINE (DBA) serial number?

No. "HYM" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies HYFOIL MARINE (DBA). The hull serial number is characters 4–8: HYFOIL MARINE (DBA)'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 HYFOIL MARINE (DBA) 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 HYFOIL MARINE (DBA) records, the title, or a marine survey to confirm the exact model and configuration.
