A seat made of drop stitch material has a back panel, a bottom panel, and a support panel, where the back and bottom panels are adjustably and detachably connected to each other at a substantially orthogonal orientation, and the support portion tilts or reclines the seat into a recumbent position which is advantageous for paddling while sitting on the upper surface of a watercraft.

A board attachment mounting assembly for mounting various attachments to a board. The assembly can allow multiple attachments to mount to a board. Further, the assembly may allow for attachments to be removed from a board (via releasing an attachment from the board attachment mounting assembly) while keeping the board attachment mounting assembly locked in place on or within a board or affixed to a board. Also, the board attachment mounting assembly may lock in place on or within a board or become affixed to a board regardless as to if an attachment has been attached to a board (via the board attachment mounting assembly). The board attachment mounting assembly can comprise a t-nut with at least one through-hole and at least one receiver, at least one flexible rod, and at least one extended t-nut with a least one through-opening, at least one angled through-opening, and at least one receptacle.

A watercraft drinking vessel holder and method for retaining a drinking vessel on a watercraft is configured to contain a can, cup, or water bottle for easy access during paddle boarding. The vessel holder attaches to a flat watercraft through multiple crisscrossing stretch cords that pass through elongated slots forming through the longitudinal of the vessel holder. The crisscrossing stretches cords retain the vessel holder substantially upright on the watercraft. The vessel holder has a flat base designed to sit flush against the surface of watercraft. A sidewall projects upwardly from the base. The sidewall receives drinking vessel, and substantially encapsulates drinking vessel. The sidewall defines multiple slots extending along the longitudinal in a spaced-apart, parallel relationship. The slots enable passage of elastic cords that crisscross therethrough. The cords are pulled down towards the base end of the sidewalls to firmly secure the vessel holder to the watercraft.

An apparatus, including: a main body (302) including at least one passage (320A, 320B) configured to pass a first cord section and an adjacent second cord section therethrough; and at least one cord lock (322A, 322B). When neither the first cord section nor the second cord section is disposed in the at least one cord lock, the main body is free to move along the first cord section and the second cord section which are disposed in the at least one passage. When the first cord section and the second cord section are disposed in the at least one cord lock the main body is not free to move along the first cord section and the second cord section. The first cord section and the second cord section can be selective moved into an out of the at least one cord lock.

A seat made of drop stitch material has a back panel, a bottom panel, and a support panel, where the back and bottom panels are adjustably and detachably connected to each other at a substantially orthogonal orientation, and the support portion tilts or reclines the seat into a recumbent position which is advantageous for paddling while sitting on the upper surface of a watercraft.

Disclosed is an electric surfboard that can determine whether or not a user is on board while the surfboard is working, and if not, can stop operation of the surfboard, and that can naturally cool heat generated from a control unit and a motor unit. The electric surfboard includes a surfboard housing, foot bindings which are put on a user, a step-out detecting unit for creating a magnetic field and attracted to the housing by a magnetic force, as well as being physically coupled to an ankle strap, in which if the user steps out of the surfboard, the step-out detecting unit being detached from the housing, thereby detecting step-out of the user, and a control unit receiving a step-out detecting signal outputted from the step-out detecting unit to send a signal for stopping operation of the surfboard.
