Which term best describes the point where a vessel is affected by both wind and current?

Leeway is the term that best describes the point at which a vessel is affected by both wind and current. When a vessel is in motion, the forces of wind and water can push it off its intended path. Leeway specifically refers to the sideways drift of a vessel caused by the wind, but it's important to note that in practice, this drift is also influenced by current.

Understanding leeway is crucial for navigation and seamanship because it helps mariners compensate for these forces when determining a vessel's actual path versus its intended course. Mariners must account for leeway to ensure they reach their destination effectively, especially in conditions where both wind and current are significant.

The other terms relate to different aspects of seamanship. Draft refers to the vertical distance between the waterline and the bottom of the hull (keel), which helps determine how deep a vessel sits in the water. Course is the intended path of a vessel through the water, while heading is the direction in which the vessel's bow points. Neither course nor heading directly addresses the impact of wind and current as leeway does.
