A paddle wheel yacht includes a ship body (1) and a ship power device that is arranged on the ship body (1) and consists of a propeller driven by a main engine. The propeller consists of two paddle wheels (2). The lower edges of the paddle wheels are lower than the bottom surface (4) of the ship body and are symmetrically arranged on the two sides of the ship body. Paddles (3) are uniformly distributed on the outer edges of the paddle wheels (2) in the radial direction and continuously flap the water surface down-backward at high speed when the paddle wheels (2) rotate at high speed. Only the tail part of the ship body contacts with the water surface and the ship body slides on the water surface, so as to avoid large water resistance and obviously improve the propulsion efficiency to realize the high speed and economical navigation of the ship.
