How a DEL REY YACHT WORKS HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example DYF45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | DYF | Identifies DEL REY YACHT WORKS, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | DEL REY YACHT WORKS'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. |

DEL REY YACHT WORKS HIN FAQ
What does a DEL REY YACHT WORKS HIN look like?
It starts with the three characters "DYF" — the Manufacturer Identification Code the US Coast Guard assigned to DEL REY YACHT WORKS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. DEL REY YACHT WORKS hulls (1987–1988) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is DEL REY YACHT WORKS still in business?
USCG records list DEL REY YACHT WORKS as out of business since 1988. 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 DEL REY YACHT WORKS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. DEL REY YACHT WORKS hulls (1987–1988) 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 DEL REY YACHT WORKS 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 "DYF" MIC the same as a DEL REY YACHT WORKS serial number?
No. "DYF" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies DEL REY YACHT WORKS. The hull serial number is characters 4–8: DEL REY YACHT WORKS'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 DEL REY YACHT WORKS 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 DEL REY YACHT WORKS records, the title, or a marine survey to confirm the exact model and configuration.
