WEST BAY BOAT BUILDERS HIN FAQ
What does a WEST BAY BOAT BUILDERS HIN look like?
It starts with the three characters "WQB" — the Manufacturer Identification Code the US Coast Guard assigned to WEST BAY BOAT BUILDERS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. WEST BAY BOAT BUILDERS hulls (1994–2002) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is WEST BAY BOAT BUILDERS still in business?
USCG records list WEST BAY BOAT BUILDERS as out of business since 2002. 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 WEST BAY BOAT BUILDERS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. WEST BAY BOAT BUILDERS hulls (1994–2002) 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 WEST BAY BOAT BUILDERS 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 "WQB" MIC the same as a WEST BAY BOAT BUILDERS serial number?
No. "WQB" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies WEST BAY BOAT BUILDERS. The hull serial number is characters 4–8: WEST BAY BOAT BUILDERS'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 WEST BAY BOAT BUILDERS 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 WEST BAY BOAT BUILDERS records, the title, or a marine survey to confirm the exact model and configuration.
