Recently the ship equipped scilling rudder is on increase. Generally, the scilling rudder is the fishshape section with end-plates and provides high lift performance. The scilling rudder displays higher handling performance than the normal one, especially in berthing controls. In the model experiment the rudder of fish-shape section with end plates provide high-capacity lift. However, the mechanism bringing strong lift force even in large rudder angle is not entirely studied yet. To know the above mechanism will give useful suggestion and information to navigator, shipbuilder and marine engineer. In this paper, as the basic research clearing up this mechanism, we examined computationally the relation between the shape of fishlike rudder section and hydrodynamic forces.
