Abstract
This float comprises a fuselage ( ) analogous to classic floats, but which here is topped by a leg ( ) such that the fuselage ( ) is completely submerged. This arrangement, combined with others that are secondary, makes it possible to reduce the vertical oscillations of the float produced by the sea swell while still ensuring good directional stability and satisfactory stability relative to other disturbances. Thus, a structure ( ) suspended from the float ( ) and which is part of a line ( ) towed by a ship remains at a constant depth. This invention can be applied, for example, to seismic tests at sea.
