A current-format (1984–present) Hull Identification Number is 12 characters. Using the example JMS45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | JMS | Identifies STELLO MARINE ENTRPR INC, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | STELLO MARINE ENTRPR INC'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. |

STELLO MARINE ENTRPR INC HIN FAQ
What does a STELLO MARINE ENTRPR INC HIN look like?
It starts with the three characters "JMS" — the Manufacturer Identification Code the US Coast Guard assigned to STELLO MARINE ENTRPR INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. STELLO MARINE ENTRPR INC hulls (1981–1983) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984.
Is STELLO MARINE ENTRPR INC still in business?
USCG records list STELLO MARINE ENTRPR INC as out of business since 1983. 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 STELLO MARINE ENTRPR INC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. STELLO MARINE ENTRPR INC hulls (1981–1983) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
Where is the HIN on a STELLO MARINE ENTRPR INC 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 "JMS" MIC the same as a STELLO MARINE ENTRPR INC serial number?
No. "JMS" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies STELLO MARINE ENTRPR INC. The hull serial number is characters 4–8: STELLO MARINE ENTRPR INC'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 STELLO MARINE ENTRPR INC 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 STELLO MARINE ENTRPR INC records, the title, or a marine survey to confirm the exact model and configuration.
