MAR-LO is a 1981 towing vessel. The Coast Guard has recorded 22 inspections since 1992, most recently in May 2025, along with 8 deficiencies and 2 casualty investigations between 2008 and 2023.
Records from 1992 to 2025. Most recent: inspection, 14 May 2025.
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 Towing Vessel class in Maury's sources begin in 1980.
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.

here: these lists are a floor, not a complete manifest.

Ownership record
