The 7 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 38 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 Barge class in Maury's sources begin in 1972.

Every line above is a field of the National Vessel Documentation Center's file as served by NOAA Fisheries, dated 10 September 2026, matched to this hull on its Official Number. Registered and ITC measurements are two systems and are never combined. One snapshot is held so far; documentation history begins with the next.
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.
No deficiencies recorded against this vessel. This means none were written in the records covered — it is not a statement about the vessel's condition. What a recorded resolution is.
Ownership record
The Coast Guard's documentation record for this hull -- the Abstract of Title,
with its owners and liens as filed -- is not in PSIX. Ask, and Maury buys it from the National
Vessel Documentation Center, files it here with its date, and every reader of this page gets it.
