Subjects will include (but not be limited to) advice on PLA procedures and/or requirements and notification of new and updated rules and regulations for navigation.

Some Notices remain effective indefinitely and these are subsequently published as Permanent Notices to Mariners. Click here to view

In addition to the Notices to Mariners below, events are also promulgated here - in the Events Calendar.
