You are underway on course 050°T and your maximum speed is 12 knots. The eye of a hurricane bears 080°T, 100 miles from your position. The hurricane is moving towards 265°T at 22 knots. What course should you steer at 12 knots to have the maximum CPA?

Question

You are underway on course 050&deg;T and your maximum speed is 12 knots. The eye of a hurricane bears 080&deg;T, 100 miles from your position. The hurricane is moving towards 265&deg;T at 22 knots. What course should you steer at 12 knots to have the maximum CPA?

Accepted Answer

Option D: 208&deg;. Executing a maximum CPA maneuver relative to a tropical cyclone requires vector triangle resolution using relative movement. Plotting the storm's course and speed against own ship's maximum speed yields a collision-avoidance course of 208°T according to Bowditch.
