Abstract
Embodiments of the disclosure include a flotation device or watercraft propelled through the water using a (ever powered propulsion system. The lever powered propulsion system includes human powered actuating levers operably connected to a reciprocating propulsion device. As a rider powers the levers up and down, that motion translates to the propulsion device, which cycles through a high drag propulsion phase and low drag recovery phase.
