You are underway on course 050°T and your maximum speed is 13 knots. The eye of a hurricane bears 120°T, 100 miles from your position. The hurricane is moving towards 265°T at 25 knots. What course should you steer at 13 knots to have the maximum CPA?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 324°T
Using relative motion vector analysis as prescribed by Bowditch for hurricane avoidance, steering course 324°T establishes the maximum Closest Point of Approach (CPA) by maximizing vector separation from the approaching cyclone's track and velocity.
