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 recorded inspection, 1972 to 2026, 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.

Ownership record

Vessel Documentation Center, files it here with its date, and every reader of this page gets it.
