Years with a record
10 calendar years (1993–2019)
The 14 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.
This record may be incomplete: the most recent inspection recorded for this vessel was 7 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 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.

The Coast Guard recorded this vessel and the following in the same inspection activity — normally a tug and the barges in its tow. A recreational or unclassed hull in the same activity is held and not published, so it does not appear here: these lists are a floor, not a complete manifest.

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.
Recorded names · 1

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.
