OCEAN TECH MARINE INC HIN FAQ
What does a OCEAN TECH MARINE INC HIN look like?
It starts with the three characters "OTM" — the Manufacturer Identification Code the US Coast Guard assigned to OCEAN TECH MARINE INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. OCEAN TECH MARINE INC hulls (1986–1999) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is OCEAN TECH MARINE INC still in business?
USCG records list OCEAN TECH MARINE INC as out of business since 1999 (associated with OCEAN TECH SERVICES). 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 OCEAN TECH MARINE INC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. OCEAN TECH MARINE INC hulls (1986–1999) 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.
