What does "leeway" refer to in the context of sailing?

In the context of sailing, "leeway" refers specifically to the lateral drift of a vessel caused by wind. When a sailboat is underway, the wind can push it away from its intended course, causing it to move sideways relative to the direction in which the vessel is actually heading. This drift can significantly affect navigation and requires sailors to account for it in their course plotting to maintain their intended track.

Understanding leeway is vital for effective sailing, as it informs how sailors adjust their sails and steering to minimize unwanted drift and to stay on course. It also emphasizes the importance of wind direction and strength, making it a critical concept for anyone handling a sailboat.
