Years with a record
7 calendar years (1984–1990)
The 18 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 36 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.

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
KNDGMMSI not assigned · expired · voluntarily equipped · granted 25 September 1986, cancelled 25 September 1991 · licensed under a name not among this hull’s recorded names (not shown)
FCC Universal Licensing System ship-station file of 6 September 2026, matched to this hull on its
US Official Number. Status and dates are the file’s own. The licensee is not read from the file and is not shown.
A lapsed licence’s MMSI is still the number the vessel transmitted under while it was valid.
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.

Ownership record
