This record may be incomplete: the most recent inspection recorded for this vessel was 16 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.

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.

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
Every record for this hull, in one document — $299

Every recorded inspection, 1972 to 2026 for this class, in one chronology · every deficiency, with system, dates and resolution · operational controls imposed and removed · every name this hull has been recorded under · the vessels it was inspected alongside, and when · how its record compares with hulls of similar age and size, as a fact about the population and never a judgement about this vessel.

Read one first, in full: a forty-year chronology · a hull that changed operators four times · the sparse case, shown as an example, not for sale.

This report is in development and is not for sale yet. There is no date, and nothing is charged. Leave an email and we will tell you when it exists, once.

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.
