A personal water craft propelled on the water's surface by the user pedaling a pedal crank that in turn rotates a propeller thrusting the craft in a forward or rearward direction. Steering is accomplished by an operator-controlled rudder at the aft of the craft. The craft is of unique design lending to persons who desire to snorkel observing undersea life in a comfortable prone position of appropriate pedal posture while enjoying the ease of navigating by pedal propulsion with less expenditure of effort than swimming.
