F W KNOWLES is a 1941 towing vessel. The Coast Guard has recorded 26 inspections since 1993, most recently in March 2024, along with 3 deficiencies — 1 with no resolution recorded — and 2 casualty investigations between 2006 and 2013.
Records from 1993 to 2024. Most recent: inspection, 14 March 2024.
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.
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.

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, 1980 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.
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 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.
Vessel lapsed DD/ISE extension date. COI is invalid until satisfactory DD/ISE is completed.
Condition: Improper/Lack of Maintenance
Action required: 701 - Prior to carriage of passengers/cargo

The OCMI has reasonable cause that the vessel's survey is deficient and requires an external survey be completed by the next scheduled survey, with the Coast Guard Marine Inspector present.

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.
