NAT CO 4 is a 1980 offshore supply vessel. The Coast Guard has recorded 11 inspections since 1980, most recently in July 1989, along with 5 deficiencies.
Records from 1980 to 1989. Most recent: inspection, 7 July 1989.
The 11 inspections in the strip above, split by the kind of activity the US
Coast Guard recorded. Years with a record are calendar years in which a record exists, not
years in service. What Maury does not do.
This record may be incomplete: the most recent inspection recorded for this vessel was 37 years ago. Maury shows what the Coast Guard recorded, not whether the vessel has been inspected since, is still in service, or what condition it is in. Coast Guard record current through 13 September 2026, retrieved 18 September 2026 from PSIX. Every field on this page was recorded by the Coast Guard. Records for the Offshore class in Maury's sources begin in 1978.

Documentation record
Tonnage as PSIX records it61 - Regulatory (Subpart C or D), Net Ton 91 - Regulatory (Subpart C or D), Gross Ton
This hull's Official Number is not in the NVDC file dated 10 September 2026 as served by NOAA Fisheries, so no documentation record is shown. Absence from that file is a fact about the file, not about the hull.
Radio station licence
No FCC ship-station licence is recorded against this Official Number in the file of
6 September 2026. That is a fact about the licence file, not about the radio.
A report is not offered for this hull: Its record holds only 2 of the seven kinds of material a report is built from: inspections, deficiencies, operational controls, tow-unit appearances, casualty records, dimensions and documentation. That is a statement about the record, not about the vessel. Reports.
