GIMLI BOATWORKS HIN Decoder — MIC ZGW
Hull Identification Numbers beginning with ZGW were assigned by the US Coast Guard to GIMLI BOATWORKS of GIMLI, MB. The company is recorded as out of business since 1997 — common for older hulls, and useful to know when hunting parts or records.

Status

GIMLI BOATWORKS built hulls across both HIN eras (1982–1997): 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 GIMLI BOATWORKS HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example ZGW45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | ZGW | Identifies GIMLI BOATWORKS, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | GIMLI BOATWORKS'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. |

GIMLI BOATWORKS HIN FAQ
What does a GIMLI BOATWORKS HIN look like?
It starts with the three characters "ZGW" — the Manufacturer Identification Code the US Coast Guard assigned to GIMLI BOATWORKS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. GIMLI BOATWORKS built hulls across both HIN eras (1982–1997): 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 GIMLI BOATWORKS still in business?
USCG records list GIMLI BOATWORKS as out of business since 1997. 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 GIMLI BOATWORKS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. GIMLI BOATWORKS built hulls across both HIN eras (1982–1997): 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 GIMLI BOATWORKS 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 "ZGW" MIC the same as a GIMLI BOATWORKS serial number?
No. "ZGW" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies GIMLI BOATWORKS. The hull serial number is characters 4–8: GIMLI BOATWORKS'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 GIMLI BOATWORKS 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 GIMLI BOATWORKS records, the title, or a marine survey to confirm the exact model and configuration.
