The video tutorial explains how to use vectors to determine the speed and direction of a boat affected by a current. It covers the basics of bearings, vector representation, and the calculation of resultant vectors. The tutorial demonstrates how to convert bearings to angles, perform vector addition, and calculate the magnitude and direction of the resultant vector. The process involves using trigonometric functions and understanding the impact of currents on navigation.
