This record may be incomplete: the most recent inspection recorded for this vessel was 6 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 Passenger Ship class in Maury's sources begin in 2016.

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.

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.
