How the wind effects hull movement is a function of wind and water on the hull - the "grip" of the bow and stern on the water,and the push of the wind on these parts,and their distance from the center of lateral resistance.Add deck cargo aft and the bow will have more tendency to point into the wind. Drop the rudder, more lateral resistance aft,and the bow will fall off
