Setting the Heading Line and Angle Markers
The heading line is an extension drawn on the map from the bow of the boat in the direction of travel. Angle markers indicate relative position from the heading or course over ground, which are helpful for casting or finding reference points.
You can show the heading line and the course over ground (COG) line on the chart.
COG is your direction of movement. Heading is the direction the bow of the boat is pointed, when a heading sensor is connected.
