years in service. What Maury does not do.

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.
