Coastal Navigation
นามธรรม
To carry out any activities at sea one needs to know how to fix positions, set a course and measure the distance. In the area of fisheries navigation knowledge is obviously essential. For instance, when a fishing boat is preparing to leave a port for a fishing ground, the planned sea route (course) must be drawn on the charts, and the course in degrees and arrival time at the fishing ground must be decided.
