Navigation Problems USCG Question #494 (Set 14)

You wish to make good a course of 300°T while turning for an engine speed of 11 knots. The set is 350°T, and the drift is 2.1 knots. Which course should you steer?

Official USCG Answer & Rule Citation

Correct Answer: Option B — 292°T

To make good 300°T with a set of 350°T, the vessel must steer to the left of the track. By plotting the vectors on a maneuvering board, the required heading to counteract the 2.1-knot drift is 292°T, effectively neutralizing the current's push to the north.
