What does "crosswind" mean in sailing?

"Crosswind" refers to the wind that blows perpendicular to the heading of the vessel. This means that if a boat is sailing straight ahead, a crosswind would come from the side. This type of wind is significant for sailors because it affects the boat's stability and course, requiring careful management of sails and rudder. Adjustments may need to be made to maintain the desired direction and to ensure the boat is balanced, as a strong crosswind can push the vessel off course or create a heeling effect. Understanding this concept is crucial for effective sailing maneuvers and safety on the water.
