2091. A twin-screw vessel is easier to maneuver than a single-screw vessel because the twin-screw vessel has which advantage?

Twin-screw vessels maneuver by generating opposing thrust from their propellers, enabling turns without rudder use. This contrasts with single-screw vessels, which rely on rudder deflection for turning, particularly at low speeds. Increased power or rudder speed are not the primary advantages, and diverting water from the rudder would impair maneuverability.
