Question 1086Navigation General
70% to passYou are underway on course 050°T and your maximum speed is 10 knots. The eye of a hurricane bears 100°T, 90 miles from your position. The hurricane is moving towards 285°T at 19 knots. Which course should you steer at 10 knots to have the maximum CPA?
A
221°
B
226°
C
233°
D
238°
AI Explanation
The correct answer is B) 226°. To have the maximum closest point of approach (CPA) with the hurricane, you need to steer a course that is perpendicular to the hurricane's track. Given that the hurricane is moving towards 285°T at 19 knots, the perpendicular course would be 226°T. This allows you to maintain the maximum distance from the hurricane's center while still making progress in your desired direction. The other options are incorrect because they do not represent the course that is perpendicular to the hurricane's track. Steering those courses would either bring you closer to the hurricane or fail to maximize the CPA.
