A kayak has a front hull portion and a back hull portion. The front hull portion has a front engagement portion. The back hull portion has a back engagement portion that mates in an assembled state with the front engagement portion to form a passenger cockpit. At least one latch is engageable between the front and the back hull portions in the assembled state. A substantial portion of the rotated front hull portion fits within the back hull portion in a stowed state.

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.

The invention relates to a watercraft, particularly a kayak having a battery compartment and motor mount for mounting a motor thereto. The kayak can be propelled either by a motor mounted to the motor mount or by manual paddling by a user of the kayak. The kayak may additionally have a seat mounted onto a track to allow the user to adjust their position as needed in the kayak. The kayak is extra wide to provide stability, while chamfered side walls allow the user to paddle with comfort regardless of the extra width. The kayak may optionally have wheels mounted thereon to facilitate handling and transport by the user.

Folding casing formed of intersecting arches or rings and stretched by inner traction elements.

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 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.
