WALTER RIDDER is a 1999 passenger vessel (inspected). The Coast Guard has recorded 21 inspections since 2016, most recently in March 2026, along with 5 deficiencies and 3 casualty investigations between 2012 and 2024.
Records from 2012 to 2026. Most recent: inspection, 11 March 2026.
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.
