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

A report is not offered for this hull. Its record holds only 2 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.
