Question 1646Navigation General

The correct answer is B) A following current of 0.9 knot. To arrive at this answer, we can calculate the speed of the vessel through the water and the distance traveled to determine the current experienced. Given: - Vessel speed: 12 knots - Distance traveled: 30 nautical miles - Time taken: 2 hours 20 minutes (2.33 hours) Using the formula: Speed = Distance / Time, we can calculate the vessel's speed through the water: Speed = 30 nautical miles / 2.33 hours = 12.88 knots Since the vessel traveled 30 nautical miles in 2 hours and 20 minutes, and its speed through the water was 12.88 knots, the current experienced must be a following current of 0.9 knot (12.88 knots - 12 knots = 0.9 knot). The other options are incorrect because: A) A head current of 2.0 knots would result in a lower observed speed than 12 knots. C) A following current of 2.0 knots would result in a higher observed speed than 12.88 knots. D) A head current of 0.9 knot would result in a lower observed speed than 12 knots.
