A vessel’s role is the Coast Guard’s word for how it was involved, and it is shown exactly as recorded: a vessel “sighted near” an incident is not a striking vessel, and involvement is not fault. Where an investigation records anyone dead, injured or missing, only the
structured fields are shown and the narrative is withheld. Property damage is the total the investigation recorded,
in dollars of the year, never adjusted. Vessel names link to the hull’s page where Maury publishes one;
an unlinked name is a hull Maury holds and does not publish, or one it does not hold.

A count of investigation records that name this structure. It is not a rate: the
Coast Guard’s record of incidents is denser in some years and districts than others
(coverage), and the record for 1991 onward
is the one Maury holds.

One recorded name under one Coast Guard unit. A grouping by name may include more than one structure.
Federal bridge record
Not matched to a federal bridge record. locks are not in the National Bridge Inventory; no federal structure record is loaded for them. Absence of a
match is a fact about the matching rule, not about the structure.
What this page is not
A fact about a structure, not a judgement about it or about anyone who owns it. Maury publishes no
score, rating or ranking for a structure, and no count or comparison for a bridge owner. A structure with no
page has no recorded involvement in the ranges Maury holds; that is not “never struck”.
