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 course should you steer?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 236°T
To maintain a desired track, use the wind/current triangle method. With a desired course of 230°T, set of 180°T, and drift of 1.7 knots, solve for the course to steer. The vector triangle requires a heading of 236°T to compensate for the current's set and drift.
