As a ship speed becomes faster, the configuration of a ship has been changing to keep high seakeeping performance in waves. A hydro-wing system is one of the choice which can support the whole or a part weight of a ship. It is necessary for comfortableness of passengers to maintain the constant vertical force acting on the hydro-wing under wave conditions. The characteristics of the hydro-wing with flap in waves is investigated with model experiments and theoretical considerations. Especially we pay attention to reduce a fluctuation of vertical force acting on the hydro-wing in waves by using the flap. As result of the research, it has been cleared that the fluctuation of vertical force in waves can deal with quasi-steady assumption under the usual condition. One method is investigated to control the vertical force acting on hydro-wing by using forcasting attack angle to wing which angle is estimated with wave profile at the ahead of the hydro-wing.
