Conventional rudders are placed behind the propeller with the rudder cross section arranged symmetrically with the rudder centre plane. But this arrangement ignores the fact that the propeller induces a strong rotational flow impinging on...
Due to the rotation of the slipstream, conventional rudders constantly operate in an apparent angle of attack. In addition to increasing drag, this also results in cavitation on the rudder blade.

How to choose this product
The ships rudder is an assembly of elements allowing the vessel to be steered. It is mounted aft of the propeller, but is controlled from the bridge.
The rudder pivots to alter the direction of the ship while sailing or maneuvering.
The rudder comprises a series of parts allowing it to pivot, though the term often is used to designate the rudder blade, alone. Usually, the rudder is mounted aft of the propeller. Thus, the propeller's wake flows over the rudder blade. In order for the ship to be controlled effectively, water flow over the rudder must reach a minimum speed, known as steerage way.
How to choose
Rudder blades have many different shapes. Each reacts differently to the water flowing over it. Rudder size should be appropriate for the size of the ship.
