A reinforced sports board comprises a foam core, a deck, and a bottom board. The deck is entirely bonded to the entire top surface of the foam core. The deck includes a first top foam skin, a second top foam skin, and a non-foamed plastic layer positioned between them, with the first top foam skin situated between the non-foamed plastic layer and the foam core. The bottom board is entirely bonded to the entire bottom surface of the foam core.

A watercraft has a hull which, in the area of the deck has a support on which parts of the upper body of a user can rest and where the user can hold on to handles. A flow channel is defined on the hull and a propelling screw is disposed in the flow channel. The flow channel has an intake port and downstream of the propelling screw a jet outlet in the stern area. A support body is disposed on the stern area in such a way that the support body extends the support by means of its support surface. In such a watercraft, a considerable increase in traveling speed can be achieved if provision is made for at least one sliding surface to be provided on the underside of the support body and for the support body to be rigidly connected to the hull.

An inflatable paddle board includes a main body including two body layers, and a peripheral enclosing strip which is integrated with the two body layers by thermal bonding to form an inflation chamber between the two body layers and the peripheral enclosing strip, the peripheral enclosing strip comprises one or more strip parts which are wrapped around edges of the two body layers.

A wave pool surfboard has a complex but effective method of manufacture. An EPS blank is molded to the approximate shape, then sanded to a final shape. A variety of strengthening materials, including ABS and several types of fiberglass, are laid down upon the top, bottom, and rails (sides) of the board, then attached to the blank with epoxy foam, which is applied with a spray gun. Special protection is given to the nose, tail, and rails of the surfboard, as these are the most commonly damaged parts in a wave pool environment. Fin boxes are installed, and then the surfboard is placed into a vacuum mold where it is fused to a pre-thermoformed ABS sheet (by heat and vacuum) which becomes the protective surface of the board. The surfboard is removed from the mold, trimmed, rail laminated, rail puttied and sanded, painted, pin-lined and finished with a UV-stable clearcoat.

An inflatable paddle board includes a main body and a side sealing strip which is adhered to two body layers of the main body to form an inflation chamber, wherein the side sealing strip includes two surface layers and a mesh layer between the two surface layers, each mesh layer comprises a plurality of first yarns and a plurality of second yarns which are perpendicular to each other, wherein the plurality of first yarns and the plurality of second yarns of at least a portion of the side sealing strip are respectively inclined with respect to a length direction of the side sealing strip.
