This is a sparse record, and that is what the archive holds. 1 inspection recorded in 1999, and no deficiencies were written. This vessel does not appear elsewhere in the 1980–2026 record for its class. An absent record is not evidence of compliance, and it is not evidence of a problem — it is the absence of a record.
The 1 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 27 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 Research Ship class in Maury's sources begin in 1980.

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.

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.
A report is not offered for this hull: Its Coast Guard record spans fewer than two calendar years. That is a statement about the record, not about the vessel. Reports.

No deficiencies recorded against this vessel. This means none were written in the records covered — it is not a statement about the vessel's condition. What a recorded resolution is.
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.
