how big is the rudder on an aircraft carrier
Nimitz-class aircraft carrier All ships of the class are powered by two A4W nuclear reactors, housed in separate compartments. They power four propeller shafts and can produce a maximum speed of over 30 knots (56 km/h) and maximum power of 260,000 bhp (190 MW).[4] The reactors produce heat through nuclear fission which heats water. This is then passed through four turbines which are shared by the two reactors. The turbines power the four bronze propellers, each with a diameter of 25 feet (7.6 m) and a weight of 66,000 pounds (30 t). Behind these are the two rudders which are 29 feet (8.8 m) high and 22 feet (6.7 m) long, and each weigh 110,000 pounds (50 metric tons).[22]
Port and starboard The term starboard derives from the Old English steorbord, meaning the side on which the ship is steered. Before ships had rudders on their centrelines, they were steered with a steering oar at the stern of the ship and, because more people are right-handed, on the right-hand side of it.[2] Since the steering oar was on the right side of the boat, it would tie up at the wharf on the other side. Hence the left side was called port.[4]
