Where is the HIN on a WARLEN LTD DBA ADIPOSE 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 "ADP" MIC the same as a WARLEN LTD DBA ADIPOSE BOATWORKS serial number?
No. "ADP" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies WARLEN LTD DBA ADIPOSE BOATWORKS. The hull serial number is characters 4–8: WARLEN LTD DBA ADIPOSE 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 WARLEN LTD DBA ADIPOSE 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 WARLEN LTD DBA ADIPOSE BOATWORKS records, the title, or a marine survey to confirm the exact model and configuration.
