An inflatable watercraft includes an upper wall, a lower wall connected to the upper wall so as to form a bottom main body, an inner wall extended longitudinally, and an outer wall also extended longitudinally. The inner wall, the outer wall and the upper wall are connected to form a tubular body around the bottom main body. Alternatively, the inner wall, the outer wall and the lower wall are connected to form a tubular body around the bottom main body. When deflated, the tubular body collapses due to gravity so that the outer wall is superposed on the inner wall.
