Qué cubre este vídeo
The center of lateral resistance (centro di deriva) represents the geometric point on the hull, keel, and rudder where water pressure counteracts leeway.0:49 The center of effort (centro velico) acts as the geometric center of the sail plan where wind force is concentrated.1:40 When these two points align on the same vertical axis, the boat maintains a neutral helm and travels in a straight line.3:14 If the center of effort sits aft of the center of lateral resistance, the boat develops a weather helm (orziera) and tends to turn into the wind.2:59 Conversely, if the center of effort sits forward of the center of lateral resistance, the boat develops a lee helm (poggiera) and turns away from the wind.3:08 Lateral weight distribution also influences these tendencies; shifting crew weight to leeward increases weather helm, while shifting weight to windward promotes a lee helm.4:14 Because most boat designs intentionally favor one tendency, the helmsman must use the rudder to maintain a straight course without creating excessive drag.3:07
