Years with a record 25 calendar years (1996–2025)

The 62 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.

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.

Documentation record

Tonnage as PSIX records it1619 - Simplified, Gross Ton
1619 - Simplified, Net 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.

Each line is an incident investigation the Coast Guard recorded with this hull among the vessels involved, with the date and the classification the Coast Guard gave it, and the bridge, lock or dam the investigation names where it names one. Involvement is not fault. The investigation narrative is not published. Source: IIR, through 2026.

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.
