Years with a record 9 calendar years (1982–2001)
The 21 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 25 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 it4382 - Regulatory (Subpart C or D), Net Ton
4382 - 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.

The Coast Guard recorded this vessel and the following in the same inspection activity — normally a tug and the barges in its tow. A recreational or unclassed hull in the same activity is held and not published, so it does not appear here: these lists are a floor, not a complete manifest.
