years in service. What Maury does not do.

Every line above is a field of the National Vessel Documentation Center's file as served by NOAA Fisheries, dated 10 September 2026, matched to this hull on its Official Number. Registered and ITC measurements are two systems and are never combined. One snapshot is held so far; documentation history begins with the next.

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.
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.
