Question 1085Navigation General70% to pass
You are underway on course 050°T and your maximum speed is 13 knots. The eye of a hurricane bears 100°T, 120 miles from your position. The hurricane is moving towards 275°T at 25 knots. If you maneuver at 13 knots to avoid the hurricane, what could be the maximum CPA?
AI Explanation
The correct answer is D) 72 miles.
To explain:
1) Given the hurricane's position, direction, and speed, as well as the vessel's course and speed, we can calculate the distance at which the vessel's closest point of approach (CPA) to the hurricane will occur.
2) Using basic trigonometry and vector analysis, the maximum CPA is calculated to be 72 miles, which makes option D the correct answer.
3) The other options are incorrect because they do not accurately reflect the maximum CPA based on the provided information.
4) This type of calculation is essential for navigating safely around hazardous weather conditions, which is a critical skill tested in the US Coast Guard Captain's License Examination.
