<P>PROBLEM TO BE SOLVED: To provide a contra pod propulsion device capable of reducing resistance component against the propulsion of a vessel and providing a part of a thrust. <P>SOLUTION: In this contra pod propulsion device, a plurality of blades are disposed on the pod part of the contra pod propulsion device so as to have the predetermined attack angle relative to propeller water flow therearound. A lift is generated by the blades to produce a propulsion force in the forward movement direction of the vessel. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
