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.

One embodiment of this invention provides a body sure article providing a planing device having an inclined shape behind a leading edge, forming a planking effect when in use and an overall size and shape that allows a specific position relative to a user's arms and/or elbows. A material is used having a density sufficient to be slightly buoyant relative to water, but is easily submerged under waves momentarily without substantial opposition force to a user duck diving.

A flexible surfboard is provided in an embodiment. The surfboard includes a foam body having a length, width, and thickness. The surfboard includes a flexible structural component tapered in at least one dimension, and disposed within the foam body. The flexible structural component has as dimensions a length, width, and thickness, and is configured to flex under induced forces during use. The flex characteristics of the flexible surfboard are primarily dependent on flex characteristics of the flexible structural component. The tapered flexible structural component is oriented within the foam body such that the length, width, and thickness of the tapered flexible structural component align with the length, width, and thickness of the foam body, respectively. The thickness of the soft body is less than the width of the soft body, and the width of the soft body is less than the length of the soft body. The thickness of the tapered flexible structural component is less than the width of the tapered flexible structural component, and the width of the flexible structural component is less than the length of the tapered flexible structural component. The length of the tapered flexible structural component is 6 to 12 inches shorter than the length of the foam body.

The present invention discloses a water skateboard apparatus, including a loading component and a number of skateboard bodies that are pushed forward together, where a number of the skateboard bodies are spaced apart, and the loading component is detachably connected to top surfaces of a number of the skateboard bodies. The water skateboard apparatus of the present invention greatly increases the loading space of the water skateboard apparatus by the loading component having a sufficient loading space. The propulsion power of the water skateboard apparatus is greatly improved by providing power through a number of the skateboard bodies. At the same time, the loading component and a number of the skateboard bodies can be installed and disassembled, which is convenient for transportation, maintenance and replacement.

A wave riding hoard is provided herein that has a body including a top, a bottom, a right edge, a left edge, a front, a rear and a length defined from the front to the rear. The bottom of the body includes one or more steps. A first channel is defined at least partially between the one or more steps. The first channel extends along at least a portion of the length of the body. At least one of the one or more steps extends at least partially around the left edge or the right edge of the body.

A wake tower assembly for use with a watercraft, including an arch portion extending across a width of the watercraft, first and second pivoting structures coupled to first and second ends of the arch portion, the first and second pivoting structures configured to attach to port and starboard portions of the watercraft to facilitate rotational movement of the arch portion between a lowered position and an upright position, and a first locking mechanism provided to the first pivoting structure including a biased pin member configured to engage an opening of the first end such that when the arch portion is rotated from the lowered position to the upright position, a biasing force of the biased pin member causes the biased pin member to engage the opening to mechanically lock the arch portion in the upright position.

Conventional surfboards enable a rider to catch a wave and ride towards the shoreline while utilizing the power of the ocean to enjoy the ocean waves uniquely. A low-profile motorized surfboard has been developed to assist riders who may have a disability or struggle to get into the position necessary to begin riding the waves. The surfboard may comprise at least one propeller and electromechanical motor, which may provide propulsion for the rider. The surfboard may have an internal power system and supporting circuitry for safe and reliable propulsion. The motorized surfboard may have a low-profile system that is collapsible and allows for the rider to enjoy the surf as if the surfboard were a conventional system. The system may also function to return the rider to the shoreline.

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.
