A propulsion system utilized primarily in watercraft, particularly kayaks and fishing boats, this mechanism allows for hands-free movement through the water. The operator uses their legs to turn pedals, which in turn rotate a propeller or fins located beneath the hull. This system offers an alternative to traditional paddling. An example application would be a kayak specifically designed with this system integrated into its construction, enabling the user to cover greater distances with less upper body fatigue.
The significance of this approach lies in its ability to improve efficiency and endurance during water activities. Benefits include increased speed, the freeing up of hands for fishing or photography, and reduced strain on arms and shoulders. Historically, similar pedal-powered systems have been employed in bicycles and other land vehicles, but their adaptation to watercraft represents a significant advancement in personal watercraft technology and accessibility.
