Question 1088Navigation General70% to pass
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. If you maneuver at 11 knots to avoid the hurricane, what could be the maximum CPA?
AI Explanation
The correct answer is A) 66 miles.
To arrive at this answer, we need to consider the relative motion between the hurricane and your vessel. Given that the hurricane is moving towards 270°T at 19 knots, and you are moving on a course of 050°T at 11 knots, the relative motion between the two is approximately 220°T at 30 knots. This means that the hurricane will pass at a minimum distance of 66 miles from your position, which is the maximum CPA (Closest Point of Approach).
The other options are incorrect because they do not accurately represent the relative motion and the resulting CPA between the hurricane and your vessel.
