    Abstract: There is disclosed a watercraft paddle apparatus operable by a user's legs and feet. In an embodiment, the watercraft paddle apparatus comprises a pair of rails positioned side-by-side and mountable to a watercraft, each rail configured to slidably receive a pedal mechanism adapted to slide back and forth along each rail. Each pedal mechanism includes a downwardly extendable paddle adapted to engage a water surface on which the watercraft is floating during a backward stride and to lift from the water surface on a forward stride, whereby a user can operate the pedal mechanism in each rail using an alternating walking or skiing motion. In an embodiment, each pedal mechanism is supported laterally by a front axle with a pair of wheels on either end of the front axle engaging the parallel rails. In another embodiment, each pedal mechanism is attached, via a rotatable joint, to a rear axle with a pair of wheels on either end of the rear axle engaging the same parallel rails as the front axle, whereby, the rotatable joint allows each pedal to be angled through a range of motion in order to support a user's foot throughout a stride.

    Abstract: A vehicle (20) consisting of a frame (22) with a pair of paddles (72) extending longitudinally and rotatably supported by the frame (22) in pendulum fashion for swinging movement between an extended position engaging the surface and a retracted position moved vertically out of engagement with the surface. A pair of foot platforms (74) are operatively connected to the paddles (72). A pair of depressors (84) interconnects the foot platforms (74) and the paddles (72) to rotate the paddles (72) between the extended position and the retracted position. The paddles (72) include a propulsion bar (86) and an oar (88) connected by a lost-motion connection to slide relative to one another between the extended position and the retracted position. The oars (88) have a fin-shape to propel the vehicle (20) over water and include a striker (90) to propel the vehicle (20) over land. The vehicle (20) allows movement over a surface of water and land using an elliptical motion similar to the natural motion of walking.

    Abstract: A personal watercraft includes a floatation member, a thrust assembly, a steering assembly, and a braking assembly. The assemblies may be actuated either mechanically or electrically. The thrust assembly is human powered, solar powered, or electric powered. The thrust, steering, and braking assemblies can be added after-market to an existing stand-up paddle board (SUP), or built into one or a plurality of SUPs during initial manufacturing. When the thrust assembly is human powered, it is leg or arm powered. When the thrust assembly is leg powered, the legs can move backward and forward in a sliding motion, up and down in a stomping fashion, or move in a loop trajectory. When the thrust assembly is arm powered, the arms can move forward/backward together or separately. The thrust assembly includes one or a plurality of paddles or flippers that are positioned to the side or under the SUP.

    Abstract: A human powered watercraft or land vehicle is described herein. A watercraft or land vehicle may have two pedals that reciprocated are in a linear or slightly curved trajectory but not a circular motion. As the two pedals are reciprocated, an output shaft is rotated in either a clockwise or counterclockwise direction when the left pedal is pushed forward or when the right pedal is pushed forward. The output shaft may be connected to a propeller of a watercraft or a land vehicle so as to propel the watercraft or land vehicle forward. The output shaft may receive rotational input through two gears mounted to the output shaft with one-way bearings that enable the output shaft to rotate in the same direction regardless of whether the left pedal or the right pedal is being pushed forward.
