The present invention provides a leisure boat for watersports that can arouse fun and interests of passengers and reduce a size and a volume of a driving device. The leisure boat comprises: a boat body to float on water; and a driving device installed on a rear of the boat body to rotate a propeller to generate propulsion. The boat body comprises: a pair of side tubes installed in a longitudinal direction to be parallel to each other and separated from each other; a floor member connecting a pair of the side tubes and having a transparent glass installed thereon; a rear side member connected to the floor member to connect rear ends of a pair of the side tubes; and a plurality of support members installed to connect a pair of the side tubes. The driving device comprises: a first case formed in a T shape; a second case having a cylindrical shape to rotatably mount a vertical portion of the first case therein; a fixing vice installed and fixed on the second case; a propulsion shaft rotatably installed on a horizontal portion of the first case; a driving pulley installed on the propulsion shaft to rotate with the propulsion shaft; a driven shaft rotatably installed on a lower end of the first case in a parallel direction to the propulsion shaft; a driven pulley installed on the driven shaft to rotate with the driven shaft; a chain belt installed between the driving pulley and the driven pulley to transfer a rotational force; a propeller installed on an end of the driven shaft and on the outside of the first case; and a propulsion handle installed on an end of the propulsion shaft and formed in a crank shape. |
