CUSTOM MARINE CTR INC HIN FAQ

What does a CUSTOM MARINE CTR INC HIN look like?

It starts with the three characters "CUZ" — the Manufacturer Identification Code the US Coast Guard assigned to CUSTOM MARINE CTR INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. CUSTOM MARINE CTR INC built hulls across both HIN eras (1980–1987): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three.

Is CUSTOM MARINE CTR INC still in business?

USCG records list CUSTOM MARINE CTR INC as out of business since 1987. 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 CUSTOM MARINE CTR INC HIN?

On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. CUSTOM MARINE CTR INC built hulls across both HIN eras (1980–1987): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.

Where is the HIN on a CUSTOM MARINE CTR 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 "CUZ" MIC the same as a CUSTOM MARINE CTR INC serial number?

No. "CUZ" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies CUSTOM MARINE CTR INC. The hull serial number is characters 4–8: CUSTOM MARINE CTR 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 CUSTOM MARINE CTR 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 CUSTOM MARINE CTR INC records, the title, or a marine survey to confirm the exact model and configuration.
