How a KETRON ANNAPOLIS GROUP HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example PIP45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | PIP | Identifies KETRON ANNAPOLIS GROUP, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | KETRON ANNAPOLIS GROUP'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. |

KETRON ANNAPOLIS GROUP HIN FAQ
What does a KETRON ANNAPOLIS GROUP HIN look like?
It starts with the three characters "PIP" — the Manufacturer Identification Code the US Coast Guard assigned to KETRON ANNAPOLIS GROUP — followed by a 5-character hull serial and a 4-character date code, 12 characters total. KETRON ANNAPOLIS GROUP built hulls across both HIN eras (1982–1991): 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 KETRON ANNAPOLIS GROUP still in business?
USCG records list KETRON ANNAPOLIS GROUP as out of business since 1991 (associated with KETRON INC). 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 KETRON ANNAPOLIS GROUP HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. KETRON ANNAPOLIS GROUP built hulls across both HIN eras (1982–1991): 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 KETRON ANNAPOLIS GROUP 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 "PIP" MIC the same as a KETRON ANNAPOLIS GROUP serial number?
No. "PIP" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies KETRON ANNAPOLIS GROUP. The hull serial number is characters 4–8: KETRON ANNAPOLIS GROUP'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 KETRON ANNAPOLIS GROUP 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 KETRON ANNAPOLIS GROUP records, the title, or a marine survey to confirm the exact model and configuration.
