A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn
balance rudder Not usually a single rudder, but a set of three or four rudders operating together to maneuver a sternwheel steamboat. Placed just forward of the paddlewheels, the effectiveness of the balance rudder is increased by the flow of water generated by the paddles, giving such steamboats a high degree of maneuverability.

The rudder is a fundamental control surface which is typically controlled by pedals rather than at the stick. It is the primary means of controlling yaw—the rotation of an airplane about its vertical axis. The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces.
In larger vessels, the rudder is often linked to a steering wheel via cables, pushrods, or hydraulics.

Like all rudders, the main effect of a Schilling rudder is to deflect the flow of water generated by the propeller.Schilling rudders are most commonly used on ships that are difficult to maneuver, particularly large ships such as container ships and oil tankers, slow-moving ships and boats, longer and narrower ships, or boats with slow-moving propellers.
A rudder command dictates changing the angle of the rudder, which is a single-event action, whereas steering a heading is a comparatively long event and will require ongoing or continuous rudder adjustments. The following are helm orders used in the United States Navy and United States Coast Guard: [2] Rudder. Midships (Bring rudder angle to 0 ...
Rounding-up is a phenomenon that occurs in sailing when the helmsman (or tiller-handler) is no longer able to control the direction of the boat and it heads up (or "rounds up") into the wind, causing the boat to slow down, stall out, or tack.
In sailing, heaving to (to heave to and to be hove to) is a way of slowing a sailing vessel's forward progress, as well as fixing the helm and sail positions so that the vessel does not have to be steered. [1] It is commonly used for a "break"; this may be to wait for the tide before proceeding, or to wait out a strong or contrary wind.
