How a CUSTOM BOAT MFG CO HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example CUS45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | CUS | Identifies CUSTOM BOAT MFG CO, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | CUSTOM BOAT MFG CO's own production number for the specific hull (the letters I, O, Q are never used). |
| 9 | Certification month | D | Month built — A=January … L=December (D = April). |
| 10 | Certification year | 4 | Last digit of the certification year. |
| 11–12 | Model year | 24 | The boat’s model year. |

CUSTOM BOAT MFG CO HIN FAQ
What does a CUSTOM BOAT MFG CO HIN look like?
It starts with the three characters "CUS" — the Manufacturer Identification Code the US Coast Guard assigned to CUSTOM BOAT MFG CO — followed by a 5-character hull serial and a 4-character date code, 12 characters total. CUSTOM BOAT MFG CO hulls (1990–present) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is CUSTOM BOAT MFG CO still in business?
USCG records list CUSTOM BOAT MFG CO of ST BERNARD, LA in the MIC database (registered 1990).
How do I decode the year on a CUSTOM BOAT MFG CO HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. CUSTOM BOAT MFG CO hulls (1990–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 CUSTOM BOAT MFG CO 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 "CUS" MIC the same as a CUSTOM BOAT MFG CO serial number?
No. "CUS" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies CUSTOM BOAT MFG CO. The hull serial number is characters 4–8: CUSTOM BOAT MFG CO'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 BOAT MFG CO 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 BOAT MFG CO records, the title, or a marine survey to confirm the exact model and configuration.
