You are underway on course 050°T and your maximum speed is 11 knots. The eye of a hurricane bears 070°T, 80 miles from your position. The hurricane is moving towards 270°T at 19 knots. What course should you steer at 11 knots to have the maximum CPA?

Question

You are underway on course 050&deg;T and your maximum speed is 11 knots. The eye of a hurricane bears 070&deg;T, 80 miles from your position. The hurricane is moving towards 270&deg;T at 19 knots. What course should you steer at 11 knots to have the maximum CPA?

Accepted Answer

Option A: 215&deg;. Navigational triangle solutions for hurricane avoidance dictate steering the course that maximizes the CPA away from the storm track. By plotting the relative motion vector using the storm's velocity and own vessel's 11-knot maximum speed, the optimum heading is 215°T.
