Grounding Alarm
The chart plotter is provided with a function that, by querying the map's data, verifies potential danger
to navigation due to shallow water, land, rocks, obstructions and shoreline constructions. The maps
are scanned periodically (every 10 seconds). When the Grounding Alarm is active, the chart plotter
scans an area in front of the boat. This area is identified by a triangle drawn in front of the boat icon
whose direction is determined by the current boat heading. The length of the triangle is user selectable
and its angle is 30 degrees. If any of the above objects are found, the chart plotter notifies the danger on
a dedicated warning message box in the Grounding Alarm Report page. The Grounding Alarm is
switched Off by default after a Master Reset. Once the Grounding Alarm has been activated, a warning
message is shown.
