Rudders
Rudders are primary control surfaces used to steer a ship or boat. They are typically flat or curved surfaces mounted on the stern of the vessel, and can be rotated to change the direction of the water flow passing by the hull. Rudders are essential for maneuvering a vessel, and are operated by a steering mechanism such as a wheel or tiller. The size and shape of a rudder depends on the size and type of vessel, as well as the intended use. Modern rudders are often made of metal or composite materials, and may be equipped with additional features such as flaps or bulbs to improve their effectiveness.
