The device comprises a plurality of deflector members (1) having a submerged lower face (2), called first face, generally fitting into the extension of the hull bottom (FC) of the ship, toward the rear thereof, while forming an angle (.alpha.) in relation to a general plane (.DELTA.) tangent to this bottom (FC), characterized by the fact that these deflector members (1) are articulated to the hull and are juxtaposed side by side, over all, or practically all, the width of the stem, control means (4) making it possible to cause it to pivot in one direction or the other in order to vary said angle (.alpha.), these means being housed in part in a protective case.
