Every vessel has a pivot point or center where it turns the best. The stern of a vessel would be hard to control if the rudder was at the bow. When docking, if the rudder was at the bow, you would never be able to get the stern of the vessel to the dock. Once you got the bow to the dock or pier, there would be no way to control the stern to make it swing. Once the bow is at the dock, with the rudder at the stern, the force of water passing across it from the propeller will push the stern into or away from the dock relative to the angle of the rudder.

What is a better phrase the rudder of a ship or the rudder on a ship?
Of the ship
What are the elements for steering the ship?
A ship is normally steered using its rudder. Dependent on vessel type this may be a single rudder or twin. The rudder is normally positioned behind the propeller. A rudder is shaped as a foil, and when the rudder is turned with water flowing over it, the rudder acts much like the wing of an aircraft and provides lift (in this case axially). the lift is a force which acts through the rudder stock and "pintle" bearings which transfer that force to the aft end of the ship, moving it. As the vessel is moving forward and the hull is shaped to pass through the water in a hydrodynamic fashion, the ship will turn. The force to turn the rudder is supplied via the steering gear. This is normally in the form of a hydraulic ram (or rams) coupled to a tiller keyed in on the top of the rudder. The hydraulic rams get a signal from the ships wheelhouse (or bridge) normally via electric solenoids. The hydraulic fluid under pressure is then admitted to the relevant cylinder, driving the rudder over. A feedback is provided to the input. The input is normally a small wheel, joystick or autopilot. The days of a large wooden ships wheel are no more! Cruise ships may have an "azipod". They would not be fitted with a rudder, but the propeller is fitted to a rotating "pod" fitted under the hull. As the pod rotates the thrust from the propeller moves the hull around.
What basic motion should a ship have in order that the rudder will be effective in turning the ship?
It should be moving forwards or backwards.

How do you turn a ship?
With a rudder
How the weight of the rudder is supported by the rudder carrier?
It helps stear, the size of the rudder depends on the size of the ship
Why was the ship's rudder invented?
to be able to steer a ship with complete control. without ship rudder many people would tip over when there on a boat.
What Device used to change direction on a ship?
magnetic compass
What is rudder trunk?
Rudder trunk is a space between carrier bearing and bush of the rudder stock of a ship's and the space is located just above rudder.
What is the process of rudder in a ship?
A rudder is a blade at the back of a boat or ship that is used to change directions. In other words, it's used to steer!
