A current-format (1984–present) Hull Identification Number is 12 characters. Using the example CBL45678D424 (illustrative):

|---|---|---|---|
| 1–3 | Manufacturer (MIC) | CBL | Identifies LONDON BRIDGE BOAT CO, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | LONDON BRIDGE 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. |

LONDON BRIDGE BOAT CO HIN FAQ
What does a LONDON BRIDGE BOAT CO HIN look like?
It starts with the three characters "CBL" — the Manufacturer Identification Code the US Coast Guard assigned to LONDON BRIDGE BOAT CO — followed by a 5-character hull serial and a 4-character date code, 12 characters total. LONDON BRIDGE BOAT CO built hulls across both HIN eras (1972–2011): 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 LONDON BRIDGE BOAT CO still in business?
USCG records list LONDON BRIDGE BOAT CO as out of business since 2011. 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 LONDON BRIDGE 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. LONDON BRIDGE BOAT CO built hulls across both HIN eras (1972–2011): 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 LONDON BRIDGE 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 "CBL" MIC the same as a LONDON BRIDGE BOAT CO serial number?
No. "CBL" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies LONDON BRIDGE BOAT CO. The hull serial number is characters 4–8: LONDON BRIDGE 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 LONDON BRIDGE 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 LONDON BRIDGE BOAT CO records, the title, or a marine survey to confirm the exact model and configuration.
