A recreational assembly includes a body, the body defining an aperture extending through the thickness of the body from the upper surface to the lower surface, and two lumens extending within the body. The assembly also includes two or more stringers removably insertable into the lumens, respectively, and a plug removably insertable into the aperture of the body. The plug includes upper and lower plates configured to be secured within the aperture. Each of the upper and lower plates includes an anchor on one side configured to connect with an end of one of the stringers.

Embodiments are disclosed of a standup paddle (SUP) board comprising a substantially rectangular shape in outline and having a length dimension that is a whole number multiple of its width dimension. A plurality of link members are disposed at spaced-apart locations along the periphery of the board's deck. Each link member can function, in a first configuration, as a handle for the board; and, in a second configuration, as a linkup for connecting the board in abutting relation to one or more other adjacently located, similarly configured standup paddle boards. With a plurality of such boards connected proximate one another in a desired configuration via such links, an extended upper surface is provided that can serve as a substantially stable platform upon which one or more persons can engage in desired activities.

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 smart clothing and backpack system enables a user to perform many actions. The smart clothing includes circuitry and/or is made of a conductive material enclosed in an insulation material. The smart clothing includes a set of sensors configured to detect body information. The smart clothing includes multiple electromagnets configured to adjust a size of the smart clothing. The electromagnets are configured to have an increased attraction to make the smart clothing tighter on the body of the user. The system includes a smart backpack to communicate with the smart clothing. The smart backpack includes a Radio Frequency IDentification (RFID) reader configured to detect RFID tags on or in items within the smart backpack. Many other features are able to be implemented with the smart clothing and backpack system. The smart clothing is able to include a wetsuit configured to communicate with a surfboard and/or a backpack.

This disclosure extends to systems, apparatus, and methods for sports board hydrofoil masts and mast-to-fuselage connection assemblies for hydrofoil sports boards. In one exemplary system, a hydrofoil mast formed as an elongated member may include a securing structure disposed in a lower region and a fuselage may include a recess into which the mast is inserted. A securing assembly may be disposed in the fuselage for actuation to secure the mast to the fuselage by interacting with the securing structure on the mast. The securing assembly may include a cam member or locking member and an actuating member. Unique hydrofoil masts constructed from composite materials having reinforcing metal members are disclosed and may be useful in the connection assemblies
