What can change a route in protected Italian marine areas? Often not the general weather, but areas, boundaries, permitted activities and permissions. 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 look at a simplified map without checking coordinates, legend and version of the regulation.
Second question: What should I do?
The operational response is to associate to each segment of the route the crossed area and its conduct. 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 contact the manager before leaving when a border or activity remains doubtful. 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.
