A board suitable for riding a wave is described. The board includes interconnected deck and bottom reinforcing zones.

A kickboard has a non-planar shape and comprises a primary panel with opposite support members laterally outside from the primary panel with a transitional section therebetween. The support members are at a rear longitudinal position and additional support shoulders may extend from a forward end of the primary panel along each lateral side to a respective support member. The rearward end defines an opening with a cavity formed between the primary panel, transitional sections, support shoulders and support members. In use, the kickboard provides substantially improved ergonomics and allows a swimmer to support her elbows on the support members with a portion of her forearms on the support shoulders, with arms in a bent position below the surface of the water. The configuration improves comfort while maintaining a favorable hydrodynamic swimming position and reducing shoulder stress.

The invention relates to a fiber reinforced structural component, which may be used in a surfboard for stand-up paddling, wave riding, wind surfing and the like, comprising a body made of plastic, wherein the body is delimited by a surface, to which a laminate layer made of a fiber mat and a matrix is undetachably connected. The surface has at least one circumferential groove-shaped recess, by means of which a predetermined partial area of the surface is delimited.

A system and method for a stand up paddle board that utilizes a vertical hollow protrusion through the paddle board that supports the propulsion system and is comprised of two assemblies; a motor and propeller assembly, and a battery and control assembly, the location of the hollow protrusion mitigating the negative aspects of propelling the board with a propeller and the extra weight of the motorized system on the board's balance and maneuverability characteristics.

A surfboard having laterally opposed pairs of axial or lengthwise grooves with the pair forming opposed rails of greater stiffness and reduced mass. At least one of the grooves of each pair is at a board edge extremity and the other groove is nearby, preferably near or on the lower side of the surfboard. The grooves may be laid up with epoxy or fiberglass.

The present invention includes a surfboard comprising a laminated frame extending along the side rails of the surfboard, the laminated frame comprising three or more layers of laminates, and wherein the laminated frame has been formed to the shape of the rocker of the surfboard. In various exemplary embodiments, the laminated frame may have one or more lateral members extending between opposing sides of the laminated frame, wherein such lateral members may be circular in cross-section, and may include one or more supports connecting the lateral members to the top surface of the surfboard. In various exemplary embodiments, two or more layers of laminates may form an internal structure extending laterally across the laminated frame from one side to the other.

An apparatus comprising a board such as a surfboard or body board is disclosed. The board comprises a top deck and a bottom. The board comprises a forward end and a rear end. The distance between the forward end and the rear end defines a length of the board. The board further comprises rails provided at side of the board, which defines a width of the board. The rails are provided in a step-like structure to reduce thickness of the rails coming in contact with wave water wall. The board further comprises a cut-section provided at bottom along longitudinal axis of the board to reduce resistance against surface of the water when in motion. The board further comprises a set of fins provided at bottom near the rear end. Further, the board comprises at least one stringer at its center to strengthen the board, reduce deformation, and add stiffness to the board.
