The present disclosure relates generally to knee braces for boats. The knee braces described herein are particularly suitable for use with lightweight, inflatable rafts and kayaks, for example packrafts used in backcountry boating. The knee braces include a fabric body and a plurality of adjustable straps configured to attach the fabric body to a side wall of the boat.

An inflatable carrying device of watercraft by a single human carrier comprising one or more inflatables having a shape to enable it to be secured to one or both shoulders of the carrier, and a shear and tensile strength to support at least in part the watercraft. Various embodiments of the inflatables include an incurvate side about 240-300 degrees to secure to the shoulders, a length extending at least transversely across the seating area of the watercraft, a length about the width of one shoulder of the carrier, and a height to provide forward visibility for the carrier to avoid obstacles. The device makes possible single human transport of watercraft which lack a design structure for solo transport such as a kayak having a cockpit and a sit-on-top kayak.

An inflatable dinghy includes a drop stitch inflatable floor made of high pressure drop stitch material; port and starboard drop stitch inflatable sides made of high-pressure drop stitch material attached at outside edges of the drop stitch inflatable floor, respectively; a rigid bow mold attached to the drop stitch inflatable floor and drop stitch inflatable sides; and a rigid stern transom attached to the drop stitch inflatable floor and drop stitch inflatable sides. The inflatable dinghy includes only three separate air compartments including the drop stitch inflatable floor and the drop stitch inflatable sides.

A pedal assembly and steering assembly are disclosed for converting an inflatable, drop stitch paddle watercraft into a pedal watercraft. The pedal assembly includes a mounting plate and mounting bracket for supporting a geared drive shaft in an opening extending through the floor of the watercraft. The steering assembly includes a rudder connected to a tiller through push pull cables.

An inflatable raft, having: a base, a sidewall, front and back ends, first and second opposite sides; a first tubular member extending between the sides to define a first arch; and a second tubular member extending from the back end to the first tubular member at a weld joint to define a second arch, at the weld joint the first tubular member has a first diameter, the second tubular member has, end to end, a second diameter that is smaller than the first diameter, and adjacent to the weld joint, the first tubular member has a third diameter that is the same as the second diameter.

A double-chambers inflatable kayak, including an upper chamber and a lower chamber which are fixedly connected to each other by a connecting portion and between which a cavity is formed, wherein the upper chamber includes a cockpit hole and a first air valve provided on the surface, the cockpit hole being in communication with the cavity, and the first air valve being used to inflate and deflate the upper chamber, and wherein the lower chamber includes a second air valve which is used to inflate and deflate the lower chamber.

An inflatable kayak constructed of drop-stitch material. When inflated, the drop-stitch members form a rigid, planar structure. To form a non-planar contour in one of the surfaces of a drop-stitch member, the opposing surface is folded over onto itself and a strip of glue along the fold adheres the opposing surface along the glue strip, thereby forming a V-fold extending into the interior of the drop-stitch member. When the member is inflated, the V-fold will alter the profile of the opposing surface and cause the first surface to project away along that profile. The V-fold can be augmented by use of a V-tape or contour member within the V-fold. Using a contour member in the V-fold creates profiles that a fold alone cannot produce.

An inflatable kayak is provided with a floor formed of a first drop-stitch inflatable chamber. A port side is formed of a second drop-stitch inflatable chamber and a starboard side formed of a third drop-stitch inflatable chamber. A flexible fabric hull panel covers an outboard bottom of the floor, and at least a portion of an outboard surface of the port and starboard side. A hull portion is flexible and may be attached to the flexible fabric hull at a forward portion to form a bow contour with a sloping ridge. The front hull portion does not extend below a bottom surface defined by the floor. A rigid skeg attached to the flexible fabric hull at a rear portion and configured to be removable.
