This record may be incomplete: the most recent inspection recorded for this vessel was 21 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 23 August 2026, retrieved 5 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.

This is a sparse record, and that is what the archive holds. 2 inspections recorded in 1997 and 2005, and no deficiencies were written. This vessel does not appear elsewhere in the 1972–2026 record for its class. An absent record is not evidence of compliance, and it is not evidence of a problem — it is the absence of a record.
Every line above is a count of records the US Coast Guard wrote, or a date it recorded. A blank resolution means none was recorded in this data; it does not establish that a deficiency is outstanding. Years with a record are calendar years in which a record exists, not years in service. What Maury does not do.

This hull's Official Number is not in the NVDC file dated 10 August 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.
Vessel history report

A report is not offered for this hull. It has no inspection history to report. A report is offered only when the record carries six or more inspections, a deficiency, or an operational control. That is a statement about the record, not about the vessel. What a sparse-record report looks like.

Inspected as a tow unit · 22

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. 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.
