The high-speed submersible vehicle with wings, called HSV here, consists of a main hull, wings and superstructure. HSV submerges by the downward lift force of the main wing when it moves while the superstructure remains above the water level. In the previous report, the possibility to submerge by the wing is confirmed experimentally and its resistance characteristics were studied. Here, the motion under the three-freedom, surging, heaving and pitching, is studied. A careful consideration is made in the arrangement of the main and tail wings to realize a stable condition by balancing all the moments. Numerical simulation of motions is carried out to find out the condition by solving the motion equation. Forces and motions are measured among the head waves and the effects of the waves are discussed. It is found that the averaged forces and the motions are slightly differ from those in the still water and that the amplitude of the fluctuations is much less than the conventional ships. The resonant wave length is so large that the seakeeping quality of HSV may be less important. The active control of the motion is expected by changing the attack angle of wings while it is operating.
