Question 1142Navigation General70% to pass
The apparent wind is zero when the true wind is _______________.
AI Explanation
The correct answer is B) the true wind is from astern and equal to the ship's speed.
When the true wind is from astern and equal to the ship's speed, the apparent wind will be zero. This is because the ship's movement cancels out the true wind, resulting in no relative wind being experienced on the ship.
The other options are incorrect because:
A) If the true wind is zero, the apparent wind will also be zero.
C) If the true wind is from astern and twice the ship's speed, the apparent wind will be in the opposite direction (from ahead) and equal to the ship's speed.
D) If the true wind is from ahead and equal to the ship's speed, the apparent wind will be from ahead and twice the ship's speed.
