The size of a rudder typically ranges from 5% to 10% of the ship's overall length, depending on the type and purpose of the vessel. Larger ships, such as tankers and cargo vessels, may have smaller rudder proportions relative to their size due to their streamlined designs, while smaller vessels often feature larger rudders for enhanced maneuverability. Overall, the rudder must be adequately sized to provide effective steering and control without adding excessive drag.
