How does leeway affect a vessel’s navigation?

Leeway refers to the lateral drift of a vessel caused by wind, currents, and other environmental factors. When navigating, understanding leeway is crucial because it directly influences the vessel's position relative to its intended course.

In practical terms, leeway can cause a vessel to deviate from its planned track, leading to navigational errors if not accounted for. For instance, if a captain is unaware of the amount of leeway affecting their vessel, they may mistakenly believe they are on course when they are actually being pushed sideways, potentially leading to hazards or missed waypoints.

Navigators must calculate and adjust for leeway in their navigational plans, often using corrections to their course to compensate for this drift. Recognizing the importance of leeway helps ensure that the vessel remains on the intended path and increases overall navigational safety.
