Restarting navigation

When you steer to avoid an obstacle or the vessel drifts, you may go off your intended course (Line 1 in Figure 8-7). Use the steer- ing or highway display to return to course.

Also, if you don’t need to return to the origi- nal course, you can go directly to the waypoint (Line 2 in Figure 8-7) using the restart func- tion as on the next page.
