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?
AI Explanation
The correct answer is D) 208°.
To explain:
1) The key is to steer a course that maximizes the closest point of approach (CPA) between your vessel and the hurricane. This means you want to steer a course that takes you as far away from the path of the hurricane as possible.
2) By calculating the relative motion between your vessel and the hurricane, the optimal course to steer is 208°, which puts you on a perpendicular course to the hurricane's track and maximizes the CPA.
3) The other options, while potentially taking you away from the hurricane, do not maximize the CPA and are therefore not the optimal course.
4) In summary, the correct answer of 208° is the course that provides the maximum CPA between your vessel and the approaching hurricane based on the given information.
