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

An enhanced kiteboarding system is disclosed, combining at least a footboard and a kiteboard. The footboard has a protruding ridge incorporated therein, and also has one or more BTLE-grain(s) embedded therein. The footboard may also have a safety beacon embedded therein. The user operating the kiteboard system can be equipped with a variety of body-wearable mechanisms, such as wrist-wearable(s), body-wearable(s), and ankle-wearable(s) that communicate with the BTLE grains, as well as other communication products. The BTLE-grains can be located near to the protruding ridge within the footboard, or in a separate location within the footboard. A method of manufacture and method of testing are also disclosed.

Methods for providing a slip-resistant, water-resistant, and antibacterial surface to a piece of sporting equipment include receiving a substrate printed with an image. The image is printed with ultraviolet curable ink and the substrate is non-silicone and includes a top printable layer printed with the image, a middle adhesive layer, and a bottom removable layer. The method includes aligning the substrate to a surface of the piece of sporting equipment, removing the bottom removable layer of the substrate, and contacting the middle adhesive layer that is exposed against the surface of the piece of sporting equipment. The method further includes smoothing the top printable layer printed with the image against the piece of sporting equipment. The substrate and the image printed with ultraviolet curable ink conforms to the shape of the piece of sporting equipment and provides the slip-resistant, water-resistant, and antibacterial surface.

Methods of tracing a lengthwise half of a board sports board and applying a substrate film cutout onto the board having the steps of centering a centerline of a tracing scale onto a center of the board, the tracing scale having an off-centerline on both sides of the centerline; aligning a centerline mark of the film with the off-centerline of the tracing scale; flipping the board over such that the board is on top of the film; tracing a trace outline of half of the board onto the film, such that the half of the trace outline is incrementally larger or smaller than the half of the board; removing a release liner from the trace outline to expose an adhesive in the film; wetting the adhesive with a solution of water and liquid soap; flattening the wetted film onto the board with a spreader; and wiping with a wiping cloth.
