The following map shows the limits of the 21 Operational NAVAREAs.
Clicking on a NAVAREA title will take you to the NAVAREA Coordinators' website where Navigational Warnings are listed. (Note not all NAVAREA Coordinators publish warnings on the World Wide Web, some only provide Notice to Mariners.)
Click here for a full list of contact details for all NAVAREA Coordinators
NB The availability of Navigational Warnings on the web does not relieve Masters / Captains of the requirement to receive Navigational Warnings via IMO/IHO approved broadcast systems, as websites are not continuously updated and not necessarily monitored for correctness.
