To provide a stability maintenance device of a gliding ship capable of suppressing the side-to-side rocking and the rapid rise of a bow elevation angle of a high-speed ship gliding at high speed on the sea surface.SOLUTION: A frame 10 protruding to the rear of a hull and a plate 11 attached to the tip thereof are provided as means and device to suppress the increase in an elevation angle above a certain level when a gliding ship suddenly rises due to high waves and so on. The frame 10 projects horizontally on a deck about half length of a total ship hull length.
