A rudder is used to steer ships, boats, submarines, aircraft, hovercraft or other vehicles that move through air or water.
History of the rudder[change | change source]
Oars mounted on the side of ships for steering are documented from the 3rd millennium BC in Persia and Ancient Egypt in artwork, wooden models, and even parts of actual boats of that times. An early example of an oar mounted on the stern is found in the Egyptian tomb of Menna (1422-1411 BC).[1] Stern-mounted oars were also quite common in Roman river navigation as proved from reliefs more than a millennium later.
A depiction of a sternpost-mounted rudder can be seen on a pottery model of a Chinese junk dating from the 1st century AD during the Han Dynasty, predating their appearance in the West by a thousand years.[2][3] The technology of stern-mounted rudder in Europe and Islam World, which was introduced by travelers in the Middle Ages, was transferred from China
