Embodiments of the present invention provide foldable boat with at least two shell members, capable of being transformed between a storage configuration and a deployment configuration. The boat comprises an aft shell and a forward shell, coupled together by respective pluralities of interlocking pleats. The storage configuration comprises the two shell members folded together to form an interior storage space for carrying supplies and gear and allows the boat to be transported via a plurality of wheels and an extendable handle. A plurality of handles enables a user to unfold the boat into the deployment configuration, and a locking rod enables the boat to be retained in said configuration while in use on water as a boat or on snow as a sled.

The present invention relates to a winged boat comprising a main body including a passenger space and a closed space at an edge, buoyant wing parts protruding from both sides of the main body, disposed in a front and a rear area of the main body, and each including a wing body protruded from a side of the main body; a buoyant space formed inside the wing body in a closed state; a water storage part disposed in an opposite direction to the main body with respect to the buoyant space and having an opening and closing part at a lower portion and an inlet formed at an upper portion, and a buoyancy control part provided in an opposite direction to the buoyant space with respect to the water storage part and adjusting buoyancy of the wing body by controlling an amount of water stored therein.

Provided is a portable foldable aquaplane, comprising a buoyancy device (9), a handle (2), a pedal board (3) and a seat cushion (5), wherein the buoyancy device (9) comprises a head buoyancy component (1) and a body buoyancy component (13); the head buoyancy component (1) is connected to a front end of the body buoyancy component (13) in a foldable manner; the handle (2) is connected to the head buoyancy component (1) via a first telescopic rod (14); and the seat cushion (5) is connected to the body buoyancy component (13) via a second telescopic rod (15). By adjusting the height of the handle (2) and of the seat cushion (5), the aquaplane is not only capable of satisfying the requirements of riding on water in a standing state, but is also capable of satisfying the requirements of riding on water in a sitting state. The foldable structure of the aquaplane makes it easy to carry and store, and same can also provide sports and entertainment for both individuals and multi-players at the same time by means of a connection hook.

The present invention relates generally to watercraft vehicles, and more particularly, to adjustable pontoon boats. More specifically to adjustable pontoons and a deployment system capable of connecting and altering positions of the adjustable pontoons with respect to a pontoon boat.

A recreational watercraft system of interconnectable, inflatable tubes that can incorporate a configurable frame that may be removably affixed at different vertical heights to attachment brackets that are axially strapped around the inflatable tubes. A plethora of accessories are available to accommodate, oars, paddles, masts, motors and the like, depending on what watercraft shape has been assembled. It can be assembled into a canoe, raft, motorboat, sailboat, fishing float etc.

A multipurpose watercraft has a pair of catamaran pontoons supported by way of a transverse control bar at forward regions thereof. The watercraft may have an arched equipment rack framework extending above rearward regions of the pontoons. The watercraft also has a pair of electric motor thrusters located respectively beneath each pontoon and the control bar comprises a pair of controls operable by hand, each control operable to control a respective thruster forwards or backwards. Alternatively, the thrusters may be remotely controlled. This configuration allows an operator to be pulled behind the control bar horizontally between the pontoons, snorkellers to be pulled behind the watercraft for recreational sightseeing and/or for remote-control rescue operations.

An apparatus and methods according to the present invention provides a human powered catamaran-styled watercraft and methods of configuring and operating the watercraft. The watercraft generally comprises at least one hull in communication with a folding collapsible frame, wherein in the frame comprises a center rack pivotally joining hulls of hull sets to provide for common pivoting of the hulls during articulation of the watercraft, thereby the hulls and frame are in further communication through a at least one pivot pad which provides for slidable pivoting of the hulls during articulation of the watercraft. A method of folding and reversibly extending the watercraft to provide for optimized storage is provided. A method of operation of the watercraft to provide for articulation of the watercraft is provided.

A watercraft includes at least one float, a first frame supported by the at least one float, and a main panel affixed across the first frame. The watercraft further includes a second frame affixed to the first frame rotatably about a first edge and a second panel affixed across the second frame. In an embodiment, the first edge includes a shared frame member belonging to both said the frame and the second frame. In an embodiment, the watercraft includes a third frame affixed to the first frame rotatably about a second edge distinct from the first edge and a third panel affixed across the third frame. In an embodiment, the watercraft includes a shade rotatably affixed to a shade support edge member of the second frame and a shade panel affixed across the shade frame. The shade frame includes a pair of shade frame edge members rotatably affixed to the shade support edge member of the second frame.

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.

A watercraft includes a pair of inflatable pontoons. Releasably affixed atop each of the pontoons and aligned therewith are inner and outer lengthwise frame members. Forward and aft beamwise frame members are affixed to the inner and outer lengthwise frame members. Primary arch members are affixed to the forward and aft beamwise frame members. A main fabric panel is stretched between the pair of primary arch frame members, the forward beamwise frame member, and the aft beamwise frame member. A motor mount is affixed centrally to the aft beamwise frame member, the motor mount being configured to removably support a motor assembly. Aft panel side members are rotatably-lockably affixed to the aft beamwise frame member and joined by an aft panel top member. An aft fabric panel is stretched between the aft panel side members, the aft beamwise frame member, and the aft panel top member.
