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?

Question

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

Accepted Answer

Option C: 13.6 knots. Determine the speed made good by calculating the resultant vector of the ship's heading and the current. With a desired course of 230°T, engine speed of 12.5 knots, and current set of 180°T at 1.7 knots, the vector sum along the track line results in a speed of 13.6 knots.
