Turn on Vessel Offset
Vessel Offset allows you to see more of the Chart View based on the speed of the boat. Vessel Offset works with Offset Speed. When
the boat is moving below the Offset Speed setting, the boat icon will be displayed in the center of the view. When the boat is moving
at or above the Offset Speed setting, the boat icon will move to the edge of the view so more of the Chart View is shown.
