What Maury does not do

No page carries a score, a rating, a grade, a colour, or an opinion about any vessel's condition or seaworthiness. Every figure on a vessel page is a count of records the Coast Guard wrote, or a date it recorded. A computed status was built once, tested against forty years of records, and deleted, because it was wrong too often to publish.

A vessel with few inspections, or none, may simply not have been inspected, or may have been inspected under a class this site does not cover. 61.7% of inspection records carry no inspection type at all, three date ranges are missing because the Coast Guard's export failed, and a hull absent from the record for years is a hull absent from the record. Nothing more is implied.

“No resolution recorded” means the record holds no resolution date. Many deficiencies are corrected on the spot and never written up again. Maury shows the blank and does not fill it either way. The same holds for an operational control with no removal date: the record has no date on which it was lifted, and that is all it says.

Maury is built by Thalor Technologies and is not affiliated with or endorsed by the US Coast Guard. The source of record is the Coast Guard's Port State Information Exchange and its incident reports; vessel documentation is held by the National Vessel Documentation Center. A correction made there is authoritative; a correction made here is an annotation shown beside the record. How to correct a record.

The site publishes every hull with a Coast Guard inspection record in a commercial class. Recreational vessels are never published, at any version of the rule: they are private boats owned by private individuals. Hulls the Coast Guard filed with no class are held and not published, for now. Commercial hulls that appear only in the documentation file, with no inspection record, have a documentation-record page that says so. The record runs from 1972 for every class, and is thin before 1985. Every inspection on record, every class back to 1972; a vessel page states the year its class's record begins beside the data vintage. 31.1% of the records come from a single Coast Guard district, so this is predominantly a record of the Mississippi–Ohio inland river system. Coverage and known gaps.

An operator page records which hulls a company filed, and never how those hulls fared. No casualty, deficiency or control figure is published for a named operator, and populations are published only where no single company's record could be read out of them.

This copy of the record runs through 13 September 2026 and was retrieved 18 September 2026. Anything recorded after that date is not here yet. A page can be accurate and still be behind.
