COASTAL NAVIGATIONAL WARNINGS

IMPORTANT :

This information is only updated during working hours 0730 -1600 Mon - Fri.

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.
