Partially submersible float comprising a module made up of a tightly closing container provided with ballast, and arrangements to vary the ballast. A frame arrangement is arranged on the container and is partially submersible during use. A horizontal tyre is supported by the upper portion of the frame arrangement. The lower part of the float, which is formed by the closed container, has the shape of a body of rotation provided with a central opening. The container which has been sealed in a water- tight manner is provided with partition walls arranged therein and forming several corresponding tanks 19, 20. Some of the partition walls form torus-shaped spaces, coaxial with the axis of rotation, thereby delimiting a plurality of annular spaces. <IMAGE> |
