535. You wish to make good a course of 230°T while turning for an engine speed of 12.5 knots. The set is 180°T, and the drift is 1.7 knots. What speed will you make good along the track line?

The speed made good along the track is the sum of the ship's speed and the current's forward component. The current's angle relative to the track determines this component, resulting in a speed made good of 13.6 knots.
