The 31 inspections in the strip above, split by the kind of activity the US Coast Guard recorded. Years with a record are calendar years in which a record exists, not years in service. What Maury does not do.

Coast Guard record current through 13 September 2026, retrieved 18 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.

Each line is an incident investigation the Coast Guard recorded with this hull among the vessels involved, with the date and the classification the Coast Guard gave it, and the bridge, lock or dam the investigation names where it names one. Involvement is not fault. The investigation narrative is not published. Source: IIR, through 2026.

Ownership record

The Coast Guard's documentation record for this hull -- the Abstract of Title, with its owners and liens as filed -- is not in PSIX. Ask, and Maury buys it from the National Vessel Documentation Center, files it here with its date, and every reader of this page gets it.
