You are underway on course 050°T and your maximum speed is 12 knots. The eye of a hurricane bears 120°T, 110 miles from your position. The hurricane is moving towards 285°T at 25 knots. What course should you steer at 12 knots to have the maximum CPA?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 346°
Per Bowditch relative movement plotting methods, a vessel with a 12-knot maximum speed encountering a hurricane bearing 120°T moving towards 285°T at 25 knots must steer course 346° to achieve the maximum possible Closest Point of Approach (CPA).
