Years with a record
11 calendar years (2016–2026)
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.

Every line above is a field of the National Vessel Documentation Center's file as served by NOAA Fisheries, dated 10 August 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.
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.

The Coast Guard recorded this vessel and the following in the same inspection activity — normally a tug and the barges in its tow. A recreational or unclassed hull in the same activity is held and not published, so it does not appear here: these lists are a floor, not a complete manifest.
