ABSTRACT:
A pedal boat mainly includes a hull equipped with a transmission mechanism and a steering mechanism. A tubular member is connected behind a lower rear end of the hull. The transmission mechanism includes a driving chain wheel, a gearbox, and a propeller connected to the gearbox via a shaft and located in the tubular member. The driving chain wheel can be rotated by use of two pedals connected thereto. Power generated by the rotating chain wheel is transmitted to the propeller via the gearbox at a high transmission gear ratio, so that the propeller rotates at high speed and expels water from the tubular member to move the pedal boat quickly in directions controlled by the steering mechanism. The propeller is located under water and would not splash water about to wet a user of the boat when it works. The pedal boat is manhandled by pedaling but capable of moving at high speed and is therefore an interesting water sport means.
