▪ ship part
 method of ship propulsion that was once widely employed but is now almost entirely superseded by the screw propeller. Early experiments with steam-driven paddles acting as oars led several inventors, including Robert Fulton, to mount the paddles in a wheel form, either at the stern or at the sides of the vessel.

      The device is highly efficient and is competitive even with modern propellers; it was supplanted by the latter because of the paddle wheel's vulnerability to damage in storms and its emergence from the water when the ship rolled heavily, which made steering difficult. For inland navigation these defects were insignificant, and paddle-wheel steamers long continued to operate on many rivers.
