Coastal Navigation - The use of position lines to determine ship's position

At appropriate intervals, during a vessel's voyage, the position of the vessel is determined and plotted on the charts. with reliable position fixing techniques, we have a safe means of monitoring a vessel's progress along a planned route. This video looks into the methods of determining the position of the vessel (ship) using position lines obtained from various means.
