ISABELLE is a 1957 offshore supply vessel. The Coast Guard has recorded 7 inspections since 1985, most recently in November 1991, along with 4 deficiencies.
Records from 1985 to 1991. Most recent: inspection, 6 November 1991.
The 7 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 35 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.

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.
Radio station licence
No FCC ship-station licence is recorded against this Official Number in the file of
6 September 2026. That is a fact about the licence file, not about the radio.
A report is not offered for this hull: Its record holds only 2 of the seven kinds of material a report is built from: inspections, deficiencies, operational controls, tow-unit appearances, casualty records, dimensions and documentation. That is a statement about the record, not about the vessel. Reports.

Ownership record

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.
