Years with a record 24 calendar years (1981–2004)
The 52 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 22 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 Offshore class in Maury's sources begin in 1978.

This hull's Official Number is not in the NVDC file dated 10 September 2026 as served by NOAA Fisheries, so no documentation record is shown. Absence from that file is a fact about the file, not about the hull.

Radio station licence

WCV3797MMSI not assigned · cancelled · compulsorily equipped · granted 6 November 1995, cancelled 5 March 2002 · licensed under a name not among this hull’s recorded names (not shown)
FCC Universal Licensing System ship-station file of 6 September 2026, matched to this hull on its US Official Number. Status and dates are the file’s own. The licensee is not read from the file and is not shown. A lapsed licence’s MMSI is still the number the vessel transmitted under while it was valid.

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.
