How a DELTA BOAT CO HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example DKO45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | DKO | Identifies DELTA BOAT CO, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | DELTA BOAT 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. |

DELTA BOAT CO HIN FAQ
What does a DELTA BOAT CO HIN look like?
It starts with the three characters "DKO" — the Manufacturer Identification Code the US Coast Guard assigned to DELTA BOAT CO — followed by a 5-character hull serial and a 4-character date code, 12 characters total. DELTA BOAT CO 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 DELTA BOAT CO still in business?
USCG records list DELTA BOAT CO of FRESNO, CA in the MIC database (registered 1985), associated with ALUMINUM ENGINEERING CO.
How do I decode the year on a DELTA BOAT CO HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. DELTA BOAT CO 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 DELTA BOAT 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 "DKO" MIC the same as a DELTA BOAT CO serial number?
No. "DKO" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies DELTA BOAT CO. The hull serial number is characters 4–8: DELTA BOAT 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 DELTA BOAT 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 DELTA BOAT CO records, the title, or a marine survey to confirm the exact model and configuration.
