A steering apparatus of a hydrofoil includes first to fourth propulsion portions, a central connecting portion, a left hydrofoil, and a right hydrofoil. Among the first to fourth propulsion portions, the first propulsion portion 41 and the third propulsion portion are disposed on the left side, and the second propulsion portion and the fourth propulsion portion are disposed on the right side. The central connecting portion connects the first to fourth propulsion portions with each other via a first fixing portion and a second fixing portion. A left hydrofoil and a right hydrofoil are respectively attached to outer sides of the central connecting portion via the first fixing portion and the second fixing portion.

A Kinetic Infinity Mount System (KIMS) comprises an outer housing, first and second outer gears, first and second inner gears, two pins, two screws, two mechanical collars, and a fin box. The KIMS allows different reusable and removable fins to be mounted onto a surfboard or other waterborne vessels. The KIMS provides dynamic, simultaneous adjustment and setting of a toe angle and a camber angle of the fin. The fin box includes two screw holes at each end and four screw holes along the side. Users choose from multiple settings of positive or negative toe angle or camber angle for each fin mounted into the surfboard. Camber and toe angles, in both positive or negative directions, can be adjusted simultaneously or separately to the user's preference. The KIMS allows different types of fins by FCS®, Futures® or similar, rectangular based fins to be mounted into the fin box and adjusted to desired configuration.

A steering system for a hydrofoil watercraft, wherein a user may ride in a seated, prone, kneeling, or standing position while steering the watercraft without the use of his or her bodyweight. Vertical elevation, left and right roll, and longitudinal direction control of the watercraft is accomplished via steering, resulting in movement of the control surfaces (fins) on the hydrofoil, thus eliminating the need for weight shifting on the flotation device. An electronic remote and/or mounted joystick steering system can be operated either electronically or through direct mechanical linkage to control the direction of the watercraft. The steering system can include an unmanned remote controlled drone hydrofoil watercraft that can be operated remotely.

A water sports device is provided which is configured for self-stabilization. The water sports device includes an active stabilization means, in the case of which the control unit provides control signals for actuators of the water sports device, actuators being active adjusting means. These can be a motor of the propulsion apparatus, adjustable flaps or nozzles, or adjustable fins, rudders, hydrofoils or individual adjustable sections thereof. Input data such as data about the position of the water sports device, power output of the propulsion apparatus, speed, acceleration and/or user inputs are evaluated in the control unit, and control commands for an actuator or a plurality of actuators are generated.

A water sports apparatus is provided, and includes a propulsion device which is provided for the propulsion of the water sports apparatus and whose motor, arranged on the float-body side, is connected in terms of drive to at least one propulsion element via an angularly and/or longitudinally movable propulsion train. The angularly and/or longitudinally movable propulsion train allows the propulsion element to be positioned optimally on the body-of-water side. The motor is arranged in a region which does not cause any body-of-water-side resistance in the operating position with a float body lifted off from the water surface. That part of the water sports apparatus which is situated in the water is optimized with regard to the design which is relevant to flow resistance in the water.
