Strategy and limitations 1

If you are in a busy shipping lane, mark you exact position, if possible, on the chart, note the positions and courses of other vessels.
Alter your course immediately to get clear of the lane and other ships as soon as you can, sailing to more shallow waters.
Use your engine if necessary.
When you navigate near the coast, pay attention to the sound signals emitted from the buoys and lighthouses.
The type of signals they emit is marked on the chart, or you can find them in the relevant pilot books.
When you are using the engine during fog, shut it down at regular intervals and listen for sound signals, either from vessels or buoys and lighthouses.
