This record may be incomplete: the most recent inspection recorded for this vessel was 8 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 23 August 2026, retrieved 5 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.
Every line above is a count of records the US Coast Guard wrote, or a date it recorded.
A blank resolution means none was recorded in this data; it does not establish that a
deficiency is outstanding. Years with a record are calendar years in which a record
exists, not years in service. What Maury does
not do.

This hull's Official Number is not in the NVDC file dated 10 August 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.

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.
