Navigation Problems USCG Question #490 (Set 14)

You are underway on course 000°T at 9.5 knots. The current is 082°T at 1.1 knots. What is the course being made good?

Official USCG Answer & Rule Citation

Correct Answer: Option A — 007°T

Vector addition of the ship's motion (000°T at 9.5 knots) and the current (082°T at 1.1 knots) determines the resultant track. Using the Law of Sines or a maneuvering board, the set pushes the vessel to the east, resulting in a course made good of 007°T.
