917. 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?

The maximum closest point of approach (CPA) is 72 miles. This is determined by the relative motion of the ship and the hurricane, considering the ship's speed and the hurricane's speed and direction. A course of approximately 335T at 13 knots yields the greatest possible CPA, limited by the ship's maneuvering speed.
