CHASER MARINE HIN Decoder — MIC CQO
Hull Identification Numbers beginning with CQO were assigned by the US Coast Guard to CHASER MARINE of OCEANSIDE, CA. The company is recorded as out of business since 1986 — common for older hulls, and useful to know when hunting parts or records.

Status

CHASER MARINE built hulls across both HIN eras (1984–1986): 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.
How a CHASER MARINE HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example CQO45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | CQO | Identifies CHASER MARINE, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | CHASER MARINE'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. |

CHASER MARINE HIN FAQ
What does a CHASER MARINE HIN look like?
It starts with the three characters "CQO" — the Manufacturer Identification Code the US Coast Guard assigned to CHASER MARINE — followed by a 5-character hull serial and a 4-character date code, 12 characters total. CHASER MARINE built hulls across both HIN eras (1984–1986): 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 CHASER MARINE still in business?
USCG records list CHASER MARINE as out of business since 1986. 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 CHASER MARINE HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. CHASER MARINE built hulls across both HIN eras (1984–1986): 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 CHASER MARINE 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 "CQO" MIC the same as a CHASER MARINE serial number?
No. "CQO" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies CHASER MARINE. The hull serial number is characters 4–8: CHASER MARINE'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 CHASER MARINE 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 CHASER MARINE records, the title, or a marine survey to confirm the exact model and configuration.
