HILLSIDE MARINE SERV HIN FAQ

What does a HILLSIDE MARINE SERV HIN look like?

It starts with the three characters "HNE" — the Manufacturer Identification Code the US Coast Guard assigned to HILLSIDE MARINE SERV — followed by a 5-character hull serial and a 4-character date code, 12 characters total. HILLSIDE MARINE SERV hulls (1972–1978) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984.

Is HILLSIDE MARINE SERV still in business?

USCG records list HILLSIDE MARINE SERV as out of business since 1978. 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 HILLSIDE MARINE SERV HIN?

On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. HILLSIDE MARINE SERV hulls (1972–1978) predate the current HIN format — expect the legacy straight-year (MMYY) or model-year (M + year + month letter) date codes used 1972–1984. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.

Where is the HIN on a HILLSIDE MARINE SERV 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 "HNE" MIC the same as a HILLSIDE MARINE SERV serial number?

No. "HNE" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies HILLSIDE MARINE SERV. The hull serial number is characters 4–8: HILLSIDE MARINE SERV'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 HILLSIDE MARINE SERV 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 HILLSIDE MARINE SERV records, the title, or a marine survey to confirm the exact model and configuration.
