Abstract
Ship hull with helicoidal channel driving to the propeller in the aft area, whose hull presents on its underside a channel of spiral or helical shape that serves as conduction to said propeller and ends in front of it and whose turns go in the contrary to the direction of rotation of said helix, which is characterized by the fact that the channel is formed and dimensioned so that the components produced by it gives the circumferential speed of the water stream entering the circuit the propeller, are directed in the opposite direction of the direction of movement of the blades of the corresponding propeller for at least two thirds of the complete revolution of the same, existing, due to these components of the circumferential speed, a ratio less than 2 between the maximum and minimum values of the thrust exerted by a pallet of the corresponding propeller on the axis of the thrust during a complete turn when the vessel is marching n speed of service, and because the outer faces of the hull that are not part of the helical channel and are below the waterline, have a shape, asymmetric with respect to the median plane of the ship.
