Abstract: A pedal-powered watercraft comprises a unitary hull having an upper wall extending from a bow portion to a stern portion of the watercraft and a pair of spaced hollow sponsons located on either side of the upper wall. The upper wall together with inner walls of the sponsons form a tunnel that opens generally downwardly and extends from the bow portion to the stern portion of the watercraft. A deck is connected to the hull and includes an elongate opening that defines a cockpit area for receiving an occupant. A seat is located in the cockpit area and a pedal assembly is connected to the hull forwardly of the seat. The pedal assembly includes a pivotal pedal tower and a pair of pedals rotatably mounted on the pedal tower. The pair of pedals are operably connected to drive the propeller during pedal rotation.
