(a) On a chart, to find the true course and distance be- tween two points; given compass error, to find magnetic and compass course and vice versa: to keep the Dead Reckoning on a chart: to lay off courses, allowing for current.
(b). On a chart, to fix the ship by simultaneous cross bear- ings, bearing and range, or by wireless cross bearings, apply- ine the necessary corrections. To fix by the bearings of one or more objects with run between, allowing for current: to find the distance at which the ship will pass a given point
(e) To avoid dangers and to use clearing marks. To use horizontal and vertical danger angles.
(d) To interpret from a chart the information it gives, particularly about buoys, lights, depths and nature of bottom. tides and tial currents. Recognition of the coast. The in- telligent use of Sailing Directions.
