Steering arrow
Map Page showing boat cruising Puget Sound, Washington (left) with Overlay Data turned on. This example shows Depth, Ground Speed and the Steering Arrow. Note that the Steering Arrow always points directly to the destination you are navigating toward. In this case, the boater is headed on a northwesterly course of 275º. Since the helms- man is on course, the Steering Arrow is pointing straight ahead. If the boat veered off course, the arrow would show which direction to steer to get back on course. Sonar Page with Overlay Data turned on (right), showing Depth, Ground Speed and the Track the boat is following.
