The invention relates to a hydrofoil for small vessels (1), comprising a front foil set (3) formed by a wing (32), with marked negative dihedral, which is attached to the vessel (1) by means of two struts (31), of circular or quasi-circular section, and a rear foil set (2) formed by a wing (22) that is flat or with minimal dihedral, attached to the vessel (1) by means of two struts (21); the front (3) and rear (2) foil sets being positioned longitudinally forward and aft, respectively, of the overall centre of gravity of the vessel, including also the pilot and/or crew.

A mount for removably installing a fin to a board used in water sports such as a surf board, wake board, windsurfing board and stand-up paddle board is provided. The mount is secured within the deck of the board and has a pivoting member pivoting between a locked position, to lock a fin to the board, to an unlocked position where the fin can be removed from the board, under hand pressure. As shown in drawing the pivoting member pivots about a pivot pin. In the unlocked position lug can be disengaged from its complementary recess (such as a notch) in the front end of the base of fin and the fin can be removed from the mount. In the locked operation the fin is fitted into channel and the pivoting member pivoted by hand pressure on a plate to cause lug to engage with notch.

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.

The invention relates to a method for constructing and/or manufacturing a water sports device (2) which has a modular structure comprising a floating body (4). The modules can be connected together via interfaces and are connected during operation. In particular, the invention relates to a method for constructing and/or manufacturing a foilboard or driver propulsion vehicle, wherein a server device is provided, and a program-controlled input interface is provided for user-defined inputs on a terminal (5), in particular a mobile terminal, which is arranged at a distance from the server device in particular. The modules are imaged in a computer program of the server device and/or of the terminal (5), and at least one outer contour of the floating body (4) of the water sports device (2) can be, in particular, freely defined by the user. On the basis of the outer contour of the floating body (4) defined in the program, automated manufacturing information is produced, and the floating body (4) manufactured according to the production information can be combined with another module, in particular multiple other modules, to produce the water sports device (2). The invention also

A holding apparatus is provided by way of which a hydrofoil surface apparatus can be retracted and extended and/or folded, out of a rest and/or starting position into its operating position and/or out of the operating position into the rest and/or starting position. Such actuation can take place manually by way of a person operating the water sports device, with the advantage of simpler transportability of the water sports device. The water sports device can already be placed in water close to the bank or beach, and can be guided or moved from there in the direction of deeper water. As soon as sufficiently deep water is reached, the hydrofoil surface apparatus can be transferred via the holding apparatus into the operating position.
