Notices to Mariners

Notices to Mariners contains safety-related information for mariners and corrections to the latest editions of the charts.

There is also a Chart Updating Service available, containing the corrections to each chart.

A new searchable NtM Online service is under development. Using the new service, it is possible to issue urgent Notices to Mariners online, without delay.
