Question 879Navigation General
70% to passYou 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?
A
215°
B
227°
C
250°
D
234°
AI Explanation
The correct answer is A) 215°. To have the maximum closest point of approach (CPA) to the hurricane, you want to steer a course that will take you as far away from the hurricane's path as possible. By plotting the hurricane's movement and your own course and speed, the optimal course to steer is 215°, which will maximize the distance between your vessel and the hurricane's track. The other options are incorrect because they do not optimize the CPA - 227° and 250° would take you closer to the hurricane's path, while 234° is not the best course to maximize the distance.
