Years with a record
10 calendar years (2016–2025)
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.

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.
