A current-format (1984–present) Hull Identification Number is 12 characters. Using the example UEF45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | UEF | Identifies SPECIALTY DESIGN CONCEPTS LLC, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | SPECIALTY DESIGN CONCEPTS LLC'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. |

SPECIALTY DESIGN CONCEPTS LLC HIN FAQ
What does a SPECIALTY DESIGN CONCEPTS LLC HIN look like?
It starts with the three characters "UEF" — the Manufacturer Identification Code the US Coast Guard assigned to SPECIALTY DESIGN CONCEPTS LLC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. SPECIALTY DESIGN CONCEPTS LLC hulls (2007–2010) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is SPECIALTY DESIGN CONCEPTS LLC still in business?
USCG records list SPECIALTY DESIGN CONCEPTS LLC as out of business since 2010. 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 SPECIALTY DESIGN CONCEPTS LLC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. SPECIALTY DESIGN CONCEPTS LLC hulls (2007–2010) 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 SPECIALTY DESIGN CONCEPTS 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 "UEF" MIC the same as a SPECIALTY DESIGN CONCEPTS LLC serial number?
No. "UEF" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies SPECIALTY DESIGN CONCEPTS LLC. The hull serial number is characters 4–8: SPECIALTY DESIGN CONCEPTS 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 SPECIALTY DESIGN CONCEPTS 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 SPECIALTY DESIGN CONCEPTS LLC records, the title, or a marine survey to confirm the exact model and configuration.
