This invention relates to a leash, an adjustable wrist attachment, and attachment features for serving as a carrying and transport device for a body board or sledding device. The connection of the leash to the body board in many embodiments is comprised of plugs in the board near the top and bottom of the board, an elastic band or cord, hook and ladder wrist connections, a loop at the top of the leash, and securing the wrist band at an opposite end of the leash to a wearer while swimming, body surfing, or sledding activities.

A swimming board having a buoyant board body having an upper surface defining, with a continuous body sidewall, a channel recessed into the board body and disposed proximal to the second end of the board body and having a strap fastening assembly coupled to the board body and with a groin strap and a waist strap that define apertures for receiving a user's legs and retaining the user to the board body.

A surfboard fin assembly for the flush incorporation into a surfboard body that allows for adjusting the depth the fin extends below the surfboard. It has a biasing means that maintains the fin in the down position yet allows upward movement upon the application of upward force such as when the fin is struck from below. The fin is perpendicularly affixed to a hinge body that is pivotally housed in an open ended fin box that is integrated into the volume of the surfboard body. A means for tensioning is releasably attached at a distal end to the hinge body and at a proximal end to the surfer's ankle. The height of the fin is adjustable through the means for tensioning and sets the performance of the surfboard to the surfer's desired level of directional control depending on their type of surfing. The fin or fin and hinge body are interchangeable with other design of fins.

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.

A bottle holder for a water sports board is disclosed. The bottle holder includes a female portion arranged for attachment to a water sports board, the female portion having sloped annular receiving surfaces surrounding a permanent magnet. A male portion is arranged to be fixed to a water bottle. The male portion has sloped annular projections arranged to engage with the female portions, enabling the bottle to be held in position by threaded engagement and by magnetic attraction simultaneously.

Cuff assemblies for sports board leashes, where the cuff assembly includes a central section that having a precurved molded insert that is configured to connect to a cord of the sports board leash, a first wing attached to a first side of the central section, and a second wing attached to a second side of the central section. The maximum width of the central section of the cuff assembly is greater than the maximum width of either of the first wing or second wing, and the first wing and second wing are configured to overlap and fasten to each other in order to secure the cuff assembly around a person's limb portion.

A tension device for securing a floating structure includes an elastic member, first and second end members, and an inelastic member. The elastic member is stretchable under tension from an unstretched length to a stretched length. The first and second end members are carried at first and second ends of the elastic member, respectively. The inelastic member is secured to the first and second end member and limits the stretched length of the elastic member.

The invention is directed toward a Rail saver with a handle. The rail saver has a handle the extends laterally away from the rail saver, creating a loop which the user can grab to maintain control over a water sports vehicle such as a long board, SUP, foil board, sail board, body board and other water sports vehicles. The rail saver with a handle is designed to add the functionality of being able to grab and control a free-floating board while in water. Grabbing and controlling an SUP board is also difficult while holding a paddle. This new functionality provides an opportunity to control a board with one hand whether or not you are holding a paddle. By holding and using the handle, the board rider avoids injury to his fingers or hands from grasping at a leash cord that is not designed to be grabbed.
