The Becker Flap Rudder with closed linkage system is the solution for the most difficult environmental conditions. Its sophisticated design incorporates the benefits of a flap mechanism, which is protected in a hydrodynamically-shaped top section of the rudder blade with a progressive flap angle ratio.

Rudder blade are classified in three ways. According to the position of the rotation axis: the rudder can be divided into the unbalanced rudder , semi-balanced rudder and balanced rudder . According to the connection type with the hull..
