Boundaries
Boundaries mark an area that you want to avoid or areas you do not want your
boat to cross. An alarm will sound when the boat or its predictor line crosses over a
boundary if you have turned on the alarm feature. Types of boundaries are: Circle
Boundaries, Closed Boundaries and Line Boundaries.
The chart will scroll if a route or boundary border extends beyond the chart window
pane. An adjacent chart will open as needed. This creates routes and boundaries
without interruption. Use the
+ and - keys to zoom in or out on the Chart window
pane when creating a Route or Boundary.
