This hydrodynamic body is welded to rudder or to main propeller axis; it transfers part of rotational momentum of wake into axial momentum thereby reduces cone vortex and increases overall thrust of propulsive system; theory and design of device; trial test arrangement and results obtained on operating ships; effect of device on propeller noise, and on intensity and persistence of wakes.
