THE RIVER BOATS AT CARR ISLAND LLC HIN FAQ
What does a THE RIVER BOATS AT CARR ISLAND LLC HIN look like?
It starts with the three characters "CIN" — the Manufacturer Identification Code the US Coast Guard assigned to THE RIVER BOATS AT CARR ISLAND LLC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. THE RIVER BOATS AT CARR ISLAND LLC hulls (2011–2014) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is THE RIVER BOATS AT CARR ISLAND LLC still in business?
USCG records list THE RIVER BOATS AT CARR ISLAND LLC as out of business since 2014. 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.

On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. THE RIVER BOATS AT CARR ISLAND LLC hulls (2011–2014) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.

Where is the HIN on a THE RIVER BOATS AT CARR ISLAND 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 "CIN" MIC the same as a THE RIVER BOATS AT CARR ISLAND LLC serial number?
No. "CIN" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies THE RIVER BOATS AT CARR ISLAND LLC. The hull serial number is characters 4–8: THE RIVER BOATS AT CARR ISLAND 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 THE RIVER BOATS AT CARR ISLAND 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 THE RIVER BOATS AT CARR ISLAND LLC records, the title, or a marine survey to confirm the exact model and configuration.
