| 1–3 | Manufacturer (MIC) | STB | Identifies STERLING BOATWORKS LLC, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | STERLING BOATWORKS LLC's own production number for the specific hull (the letters I, O, Q are never used). |

STERLING BOATWORKS LLC HIN FAQ
What does a STERLING BOATWORKS LLC HIN look like?

How do I decode the year on a STERLING BOATWORKS LLC HIN?

STERLING BOATWORKS LLC hulls (2012–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 STERLING BOATWORKS LLC 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 "STB" MIC the same as a STERLING BOATWORKS LLC serial number?
No. "STB" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies STERLING BOATWORKS LLC. The hull serial number is characters 4–8: STERLING BOATWORKS LLC'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 STERLING BOATWORKS LLC 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 STERLING BOATWORKS LLC records, the title, or a marine survey to confirm the exact model and configuration.
