Question 1057Navigation General

70% to pass

The largest waves (heaviest chop) will usually develop where the wind blows _______________.

A in the same direction as the flow of the current
B over slack water
C at right angles to the flow of the current
D against the flow of the current
AI Explanation

The correct answer is D) against the flow of the current. The reasoning behind this is that when the wind blows against the current, it creates the largest and heaviest waves or chop. This is because the wind is working against the flow of the water, causing the waves to build up and become more pronounced. The other answer choices are incorrect because: A) when the wind blows in the same direction as the current, the waves tend to be smaller and less pronounced; B) slack water has minimal current, so the wind's effect on wave formation is reduced; and C) waves at right angles to the current are not as affected by the opposing forces as when the wind blows directly against the current.
