And the bottom weight body 2 is composed. The pontoons 13 are arranged in point symmetry according to the central axis 12, thereby forming a polygonal pattern structure. In the embodiment of the present invention, the pontoons 13 are designed in a cross-shaped arrangement, and the purpose is to pursue stability. After the same amount of water is injected into the pontoons 13 respectively, the floating body 1 can be placed on the cross.
