The present invention relates to a novel water sports device that allows a user to perform water skiing and other activities while sitting on the device. The device includes a toboggan style structure positioned atop a pair of water skis. The pair of skis are secured to the underside of the toboggan using a plurality of panels or supports so that the skis partially overlap and extend beyond the edges of the toboggan. Each of the pair of skis comprise a binding which is sized and configured to accommodate a foot of the user while sitting on the toboggan. The device provides enhanced balance, buoyancy, and floating capability, and also comprises a backrest for supporting the back of the user while enjoying the device on the water.

Provided is a water track marker (1) for marking a sports track, such as a water ski track, on a water surface (20). The water track marker comprises at least a first marker ejector (11) configured to eject marker projectiles (2) towards the water for creating an instant marking (3) on the water surface (20) upon impact with the water surface (20). Provided is also a method for marking a sports track and a towing boat comprising said water track marker.

A water ski ramp that can be selectively adjusted to provide a variety of launch heights for a jumper is provided. The water ski ramp includes a floating dock comprising a first dock portion and a second dock portion operatively connected to the first dock portion, in which the first dock portion and the second dock portion define an obtuse angle ‘α’ therebetween. The water ski ramp also includes a jumping platform operatively connected to the second dock portion via a dock-to-surface hinge. The water ski ramp may also include an adjustable lift including a first end operatively connected to the first dock portion and a second end operatively connected to the jumping platform, in which the adjustable lift and the first dock portion define an acute angle ‘β’ therebetween.

A water ski system includes an elongate ski body member having an aft end portion with a mounting face. Interchangeable tail members having an engagement face are configured to be selectively mounted to the ski body such that the engagement face of the tail member abut the mounting face of the ski body member. Attachment hardware removably fixes the selected tail member to the ski body member. The interchangeable tail members may have a variety of shapes and lengths, allowing a skier to customize the water ski to accommodate differing water ski styles, water, conditions, and skill levels.

A motorized board similar to a surf board is presented for use on a water surface. The motorized board includes a base board having a front end and a back end, a foot pedal on the base board, wherein the foot pedal is rotatable on the base board, and a motor coupled to the base board and connected to a propeller at the back end, the motor being controlled by the foot pedal. A user can stand on the board and turn the motor on with his foot, as well as control the speed with his foot to ride on a water surface with or without waves.

The invention relates to floating devices for leisure and sports, and more particularly to water skis equipped with hydrofoils. The technical result is as follows: using claimed device, the user can travel not only on the water surface, but also on land without removing skis, as well as glide on hydrofoils or in a conventional water ski mode, and perform acrobatic maneuvers. The present device for the practice of a water sport comprises a pair of water skis. Each ski is comprised of a nose part and a tail part. The nose part is connected to the tail part by means of hinged fastenings. Water skis are equipped with a hydrofoil that can be flush with the bottom surface of the water ski.

A personal bipedal watercraft includes a pair of skis. Each ski of the pair of skis includes a floating hull. A deck is secured to the hull. A binding on each deck is configured to receive a foot of a user. A plurality of paddle assemblies are moveably secured to an underside of the floating hull. The paddle assemblies each include a blade and a fin.
