The Canadian Coast Guard publishes and continuously updates a set of Navigational Warnings (NAVWARNs) containing information about changes to navigational aids and current marine activities or hazards that may impact the safety of navigation.

With Aqua Map, you can display Canadian NAVWARNs on the map and access all their information. Additionally, Aqua Map updates the data daily with the published NAVWARNs.
NOTE: An active Master subscription is required to access Canadian Coast Guard data.

Coast Guard Settings

From the general Settings page, you can open the Coast Guard data settings page, where you can manage the feature.

Please note that on this page, you can manage data from different Coast Guard countries, currently including the United States and Canada.

From the top, there is first a common section to manage the database:

• Download Coast Guard DB: to enable the download and update of the Coast Guard database. Remember the label says, this information is available only in the US & Canada.
• Update now: to immediately download the latest available database.
• Automatic update: you can choose the automatic update logic: "Never" will never update the database automatically (you will need to manually press the "Update now" button), "WiFi" will do an automatic daily update each time the app is active and connected to a WiFi network, and "Always" will update the database daily with any type of data connection (even cellular connection). NOTE: with the "Always" option, you may incur extra costs depending on your mobile contract.

This data is also available in the United States provided by the USCG (see USCG Data).

• Enable Canadian Coast Guard NAVWARNs on map: to display the data on the map.
• Icon size on Map: to select the preferred icon size on the map.

As soon as you enable the data, you will see points, lines, and areas on the map, each representing a specific NAVWARN (the icon used to represent the NAVWARNs is ).

Like with all objects on the map (see Map Information page for more info), tap on the object (point, line, or area) to access the content of the NAVWARN.
