How a BROOKS BOATS HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example BBK45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | BBK | Identifies BROOKS BOATS, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | BROOKS BOATS'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. |

BROOKS BOATS HIN FAQ
What does a BROOKS BOATS HIN look like?
It starts with the three characters "BBK" — the Manufacturer Identification Code the US Coast Guard assigned to BROOKS BOATS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. BROOKS BOATS hulls (1992–2019) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is BROOKS BOATS still in business?
USCG records list BROOKS BOATS as out of business since 2019. 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 BROOKS BOATS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. BROOKS BOATS hulls (1992–2019) 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 BROOKS BOATS 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 "BBK" MIC the same as a BROOKS BOATS serial number?
No. "BBK" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies BROOKS BOATS. The hull serial number is characters 4–8: BROOKS BOATS'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 BROOKS BOATS 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 BROOKS BOATS records, the title, or a marine survey to confirm the exact model and configuration.
