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?

Correct Answer: Option B — 007°T

Vector addition of the ship's velocity (000°T at 9.5 knots) and the current (082°T at 1.1 knots) determines the course made good. Using the law of sines or a vector diagram, the resultant track is 007°T, representing the actual path over the ground relative to the water.
