A stand-up paddle with a shaft (3) arranged between a paddle blade (1) and a handle (2) is described. In order to design the stand-up paddle in such a way that paddle strokes on stand-up paddle boards can be performed, in particular by inexperienced users, without the risk of loss of balance, it is suggested that the handle part (2) is attached to the end of the shaft (3) opposite the paddle blade (1) by means of a tension-resistant, flexible connecting element (4).

The invention relates to an aquatic shoe consisting of a shoe body (1), a pair of wings (3) and floats (4, 4), characterized in that the wings (3) are symmetrical, glued together, and linked to the shoe body (1), below the shoe, so as to constitute a part of the sole (2) of the shoe, and in that the float (4) is integrated below the wings (3), at the sole (2), so that one of its faces covers the sole (2), and in that the wings (3) are fixed by a pivot connection on both sides of the shoe, so that they descend when the foot ascends into the water and rise when the foot goes down into the water so that they return to their original position. The invention also relates to the use of footwear in the fields of recreational water and/or sport and in the paramedical fields. The shoe according to the invention can be used for the rehabilitation of animals.

The present invention discloses a water skateboard apparatus, including a loading component and a number of skateboard bodies that are pushed forward together, where a number of the skateboard bodies are spaced apart, and the loading component is detachably connected to top surfaces of a number of the skateboard bodies. The water skateboard apparatus of the present invention greatly increases the loading space of the water skateboard apparatus by the loading component having a sufficient loading space. The propulsion power of the water skateboard apparatus is greatly improved by providing power through a number of the skateboard bodies. At the same time, the loading component and a number of the skateboard bodies can be installed and disassembled, which is convenient for transportation, maintenance and replacement.

An elliptical powered watercraft includes a buoyant platform, a paddle wheel, pedals operatively connected to the paddle wheel, and a skeg, a fin, or a rudder operatively connected to a steering device, such as handlebars or a steering wheel. An operator propels the elliptical powered watercraft by balancing on the buoyant platform, generating rotational movement with the pedals to deliver power to the paddle wheel, and steering the elliptical powered watercraft by turning the skeg, the fin, or the rudder with the handlebars or the steering wheel.

A flotation system, including a plurality of flotation shoes to float on a body of water, the plurality of flotation shoes including a first shoe to receive a first foot of a user therein, a second shoe to receive a second foot of a user therein, and a plurality of connecting members removably connected to at least one of the first shoe and the second shoe to bind the first shoe to the second shoe, and a support device to facilitate at least one of walking on a ground surface and movement on the body of water.

A water riding apparatus is provided for moving along the surface of water in cross-country skier type fashion. The water riding apparatus includes a first pontoon having an elongate hull and a second pontoon having an elongate hull. The first and second elongate hulls are connected together for relative parallel longitudinal motion by a gliding mechanism affixed to inner sides of the first and second elongate hollow hulls. The first and second elongate hulls include foot well openings allowing the user to stand on the bottoms of the hulls at a location below the water line of the hulls. The water riding apparatus further includes a personal stabilizer system for supporting a user in a standing position. The first and second elongate hulls can be locked in a parallel, transversely aligned relationship to allow alternative use of the water riding apparatus in a sitting, kayak-type fashion.

The invention relates to water ski (1) having a buoyant ski body (2), to which, in addition to a binding (3), a propelling drive is assigned, which comprises a rotary drive unit with a rotary drive (4) and a screw drive which can be driven thereby, and having a control device (6) for presetting a drive power. In order to create advantageous drive conditions, it is proposed that the water skis (1) of a pair of water skis each comprise a rotary drive unit with at least one drive sensor (7) each, an associated energy storage device and a communication device, which adjusts the rotary drives (4) of both water skis (1) as a function of drive sensor data and preset data of the control device (6).

The disclosed invention is a user-propelled device with no moving parts. The user places a single ski on each foot, the skis being independent from one-another. As the user strides the natural motion of his legs causes the skies to rise and fall with respect to the surface of the water. This rising and falling motion, and the resulting weight shift of the user, engages and disengages a plurality of paddles. Through this natural motion, the paddles are engaged when the foot is moving backward with respect to the user, and disengaged when moving forward with respect to the user. The result is forward motion with a natural gait, with automatic paddle engagement and disengagement.
