What can change a route in Italian coastal navigation? Often not the general weather, but radio listening and management of security messages. This is why the control should be carried out on the single route and not in a generic way.
First question: where is the notice?
Coordinates, date, time and categories of units determine the application of the arrangement. The problem to prevent is to keep the device on with volume or bad regulated squelch, believing that it is still listening.
Second question: What should I do?
The operational response is to test the VHF before departure and assign control to a trained person. If you can't bring it back to the navigation plan, reading is not yet complete.
Third question: where can I deviate?
It is sensible to have a second appropriate means of communication without considering the phone always available. Also check publications of the Hydrographic Institute, Orders of the Coast Guard and communications of the competent local authority. Effective prudence arrives before the emergency: change program in advance keeps options, autonomy and clarity.
