TUFFLINE OF MARIANNA INC HIN FAQ
What does a TUFFLINE OF MARIANNA INC HIN look like?
It starts with the three characters "TOF" — the Manufacturer Identification Code the US Coast Guard assigned to TUFFLINE OF MARIANNA INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. TUFFLINE OF MARIANNA INC hulls (1994–2002) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is TUFFLINE OF MARIANNA INC still in business?
USCG records list TUFFLINE OF MARIANNA INC as out of business since 2002. 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 TUFFLINE OF MARIANNA INC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. TUFFLINE OF MARIANNA INC hulls (1994–2002) 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 TUFFLINE OF MARIANNA INC 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 "TOF" MIC the same as a TUFFLINE OF MARIANNA INC serial number?
No. "TOF" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies TUFFLINE OF MARIANNA INC. The hull serial number is characters 4–8: TUFFLINE OF MARIANNA INC'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 TUFFLINE OF MARIANNA INC 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 TUFFLINE OF MARIANNA INC records, the title, or a marine survey to confirm the exact model and configuration.
