You are underway on course 120°T and your maximum speed is 12 knots. The eye of a hurricane bears 150°T, 120 miles from your position. The hurricane is moving towards 295°T at 20 knots. If you maneuver at 12 knots to avoid the hurricane, what could be the maximum CPA?

Correct Answer: Option D — 117 miles

Applying relative motion principles on a maneuvering board, you plot the hurricane's movement vector and your vessel's speed circle. By selecting the course that maximizes the perpendicular distance from the storm's track to your vessel's position, the calculated maximum CPA for these specific parameters is 117 nautical miles.
