A portable inflatable diving float that includes an inflatable float body is revealed. The float body consists of a horizontal portion provided with a left folding area formed on the left side and a right folding area formed on the right side. After the left and the right folding area being folded to a middle portion of the float body, a left edge portion of the left folding area and a right edge portion of the right folding area are connected by a first connection member and kept in the folded state. A flat body formed after deflation of the float body becomes a backpack body with smaller area. At least one strap member is connected between the top end and the bottom end on a front side or a back side of the float body so that users can carry the backpack body on their back.

The invention relates to a surfboard having a hull (22) and a jet drive (2) arranged in the hull (22) and a battery arranged in the hull (22) for the jet drive (2), wherein the jet drive (2) is mounted on a carrier (17) and the carrier (17) can be releasably fastened to the hull (22) by fastening means and can be removed from the hull (22) together with the jet drive (2) after the release of the fastening means.

The invention relates to a water board (2) made of a material that can float on water, having a support area (8), on which a user rests at least partially. To reduce the current forces acting on the user while holding on to and being towed behind a motorized watercraft (24), it is proposed that the water board (2) has, at a front-end area, an attachment segment (22) for the articulation of the water board (2) to the watercraft (24).

The present disclosure relates to an inflatable structure transformable between a deflated state and an inflated state, the inflatable structure comprising a drop stitch fabric having a first layer and a second layer tethered by drop stitches. At least one layer of the first and second layers comprises a ridge formed by a folded portion of the one layer, secured by a fixation line. The disclosure also relates to a manufacturing method of an inflatable structure in accordance with the foregoing, and an inflatable seat comprising such an inflatable structure.

A swim platform for attachment to a boat includes a rearwardly tapered inflatable body including a top surface capable of supporting a standing person, an outer perimeter including a forward wall, an aft wall, and a port sidewall and a starboard sidewall extending between the forward wall and aft wall. The forward wall is positionable adjacent the transom. The forward wall is longer than the aft wall and is configured not to extend laterally beyond the starboard and port sides at the transom. The swim platform may be left in the water while the boat is moving and is designed not to interfere with the boat's wake.

A fin mount for an inflatable watercraft is an apparatus used as a universal fin box that connects a variety of fins. The apparatus includes a clamp and a fin. The clamp mounts the fin into a fin box-receiving hole of an inflatable watercraft. The clamp includes a lower press, an upper press, and a length-adjustable fastener. The lower press and the upper press seal the fin box-receiving hole. The lower press and the upper press tighten together with the length-adjustable fastener. The lower press and the upper press tensionably tether to each other by the length-adjustable fastener. The apparatus further includes a fin-attachment mechanism that secures the fin into the lower press. The fin removably attaches into a fin-receiving slot of the lower press. The apparatus further includes a plurality of lower counterforts and a plurality of upper counterforts which structurally reinforce the lower press and the upper press.
