Years with a record 5 calendar years (2016–2024)

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.

Every line above is a field of the National Vessel Documentation Center's file as served by NOAA Fisheries, dated 10 August 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.

Vessel history report

A report is not offered for this hull. Its record holds only 1 of the seven kinds of material a report is built from: inspections, deficiencies, operational controls, tow-unit appearances, casualty records, dimensions and documentation. That is a statement about the record, not about the vessel. What a sparse-record report looks like.

Deficiency record · 0

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.
