Question 1087Navigation General
70% to passYou are underway on course 120°T and can make 12 knots. The eye of a hurricane bears 150°T at 120 miles. The hurricane is on course 295° at 20 knots. What course should you steer at 12 knots to have the maximum CPA?
A
312°
B
330°
C
348°
D
001°
AI Explanation
The correct answer is C) 348°. To determine the course to steer for maximum closest point of approach (CPA) to the hurricane, we need to consider the relative motion between the vessel and the hurricane. By steering a course of 348°, the vessel will be on a course perpendicular to the hurricane's bearing, which will result in the maximum CPA. The other options are incorrect because they do not provide the optimal course to maximize the CPA. A course of 312° or 330° would result in the vessel getting closer to the hurricane, while a course of 001° would not be perpendicular to the hurricane's bearing.
