Recently, according to the growth of demand about large container carrier, the studies for cavitation of semi-spade rudder were increased. In spite of many effort to solve, the fundamental solution can not be found. So, the studies for full-spade rudder are increasing to solve. In Pusan national university, the studies for full-spade twisted rudder and full-spade wavy twist rudder were carried out. However, most studies are carried out in numerical analysis and the many studies of experimental comparison between each rudder are not exist. This paper describe design history of full-spade rudder (twist rudder, wavy twist rudder) for KCS (KRISO Container Ship) and compare performance of each designed full-spade rudder about resistance and self-propulsion with conventional rudder (semi-spde rudder). The measurement about designed rudder's rudder force will be performed near future.
