Years with a record
8 calendar years (2016–2025)
Every line above is a count of records the US Coast Guard wrote, or a date it recorded.
The counts in the strip above are the same counts; this table splits the inspections by
the kind of activity 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.

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.
Vessel history report
Every record for this hull, in one document — $299
What it gives that this page does not: the whole record in one dated, citable document — every line with its Coast Guard activity id, the retrieval date on the cover, built to print to PDF with its page breaks — that a surveyor can attach and a lender can file. The same facts as this page, complete and in one file.
Every recorded inspection, 2016 to 2026 for this class, in one chronology · every deficiency, with system, dates and resolution · operational controls imposed and removed · every name this hull has been recorded under · the vessels it was inspected alongside, and when · how its record compares with hulls of similar age and size, as a fact about the population and never a judgement about this vessel.
Read one first, in full: a forty-year chronology · a hull that changed operators four times · the sparse case, shown as an example, not for sale.
A request, not a checkout: leave an email and Maury replies once, with the dated document for this hull and a Stripe invoice for $299. Nothing is charged before the document is in your hands.
Used only to answer this request. Not shared, not sold, and not added to a mailing list.

A ship when in a port of another Contracting Government is subject to control by officers duly authorized by such Government concerning operational requirements in respect of the safety of ships, when there are clear grounds for believing that the master or crew are not familiar with essential shipboard procedures relating to the safety of ships. The fire team did not properly don firefighting equipment. The crew was not familiar with SCBA operations, which resulted in dispensing 02 SCBA bottles. Additionally, crew was not familiar with shipboard firefighting procedures, such as not securing ventilation. This resulted in a failure of their fire drill 02 times.
07 - Fire Safety › N/A - No Subsystem › Fire prevention structural integrity
Issued 23 October 2025
No resolution recorded
The purpose of this regulation is to contain a fire in the space of origin. For this purpose, the following functional requirements shall be met. (1) the ship shall be subdivided by thermal and structural boundaries (2) thermal insulation boundaries shall have due regard to the fire risk of the space and adjacent spaces: and (3) the fire integrity of the divisions shall be maintained at openings and penetrations. The galley, accommodation spaces, and the navigation bridge are not separated by thermal or structural boundaries. The fire control plan fails to indicate any "A" or "B" class divisions throughout the ship. This deficiency constitutes a significant and unmitigated hazard of both fire and safe navigation if the bridge fills with smoke while underway.

A single ventilation system connects the galley, the accommodation spaces, and the navigation bridge without complying with the precautions in the specified paragraphs. Of note, the ducts were neither insulated to "A-60" standard nor fitted with fire dampers. When asked how they would secure the galley ventilation in the event of a fire, the crew could not answer the question. This deficiency constitutes a significant and unmitigated hazard of both fire and safe navigation if the bridge fills with smoke while underway.

This alarm sounder system need not be an integral part of the detection system. The smoke detectors in the galley and accommodation spaces were modular isolated household smoke detectors that were connected to a fixed system and did not initiate a visual and audible signal at the control panel.
