Abstract
The invention relates to a seacraft characterised by buoyancy ensured by liquid stored up within the seacrafts arrangement and presenting special weight lower than that of the environment. The control and propulsion forces are exclusively applied to the part A located at the terminal front section. None kind of flow arrangement or propulsion unit is configurated or adapted to the external surface of the part B which is confined between the part A and the rear end of the seacraft. The parts A and B can be independent and interconnected in such a way that their relative rotation around the symmetry shaft can be feasible so that, since the section B is by rotation symmetrical in shape and its gravity centre coincide with its symmetry axle, its rotation about the rotation shaft can be possible independently from the part A; in this way the orientation of the systems which are unbreakably adapted to the part B is achieved around the symmetry axle without repercutions involved for the seacrafts navigation data.
