A collapsible kayak may include a single-piece hull including a plurality of crease lines along which the hull is foldable. A floorboard lines a midship portion of the hull between a bow portion and a stern portion, and the floorboard includes a base and a pair of outboard walls permanently fixed at distal ends to port and starboard gunwales of the hull. The bow, stern, and midship portions are configured as a tri-fold, such that the bow portion and the stern portion of the kayak are foldable toward each other to overlap the midship portion of the hull when collapsed.

An inflatable watercraft of the kayak type including a hull including: a longitudinal bottom comprising a central longitudinal edge and two lateral longitudinal sides, so as to have a V-shaped cross section, the bottom comprising at least one inflatable shell, and a stiffening upper structure comprising two lateral longitudinal inflatable shells and at least one transverse element mounted between the two lateral inflatable shells, each lateral inflatable shell being mounted on one of the lateral longitudinal sides of the longitudinal bottom, in which each of the two lateral inflatable shells comprises two superimposed walls, each of said walls including a textile mat and being connected together by a multitude of connecting threads distributed over the entire surface of said mats while forming a structure suited to be inflated to a pressure capable of stiffening said structure.

A floating motorized picnic table includes a floatation device; a base; benches attached to the base; tabletop supports; a tabletop attached to the tabletop supports; a motor; and a battery electrically connected to the motor. The base frames and rests upon the floatation device. The benches include bench boards attached above and parallel to the floatation device. The tabletop supports are attached between the benches. The tabletop includes top boards. The battery is mounted on the base under the top boards. The motor is mounted at one end with a retractable keel located adjacent to the opposite end.

A watercraft includes a plurality of separable body sections (2101, 2102, 2103, 2104, 2105, 2106) configured for assembly into a single assembled structure (2100) having a first length, and for packing into a packed structure (3000) having a second length smaller than the first length. The single assembled structure may be held together using latching devices, one or more of the latching devices including a latch unit comprising a latch support, a spring mount and a band spring, the band spring having a first spring end and a second spring end, wherein the latch support includes a latch and a first shaft positioned in relationship to the latch, the first shaft configured for rotatably mounting the first spring end of the band spring, and the spring mount includes a second shaft configured for rotatably mounting the second spring end of the band spring.

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.

A kayak having a main body and at least one telescoping extendable insert. The extendable insert can expand out of and collapse into the main body of the kayak, allowing for the kayak to be more compact for storage and transport. The telescoping extendable inserts of the kayak latch into place when the kayak is fully extended. An automatic spring-loaded catch mechanism helps secure the telescoping extendable inserts in place before they are latched together by the user.
