Question 1084Navigation 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. If you maneuver at 10 knots to avoid the hurricane, what could be the maximum CPA?
The correct answer is C) 53 miles. To arrive at this answer, we need to calculate the closest point of approach (CPA) between your vessel's position and the hurricane's path. Given the course and speed of both your vessel and the hurricane, we can use basic trigonometry to determine the maximum CPA. With your vessel on a course of 050°T at 10 knots and the hurricane moving towards 285°T at 19 knots, the relative motion between the two puts the hurricane's closest point of approach at 53 miles from your position. This is the maximum CPA you can expect if you maneuver at 10 knots to avoid the hurricane. The other answer choices are incorrect because they do not accurately reflect the maximum CPA based on the provided information and calculations.
