The kayak preferably has a topside axial enclosure, which may be rendered watertight and used as a bait tank or other liquid container, and typically at least one additional enclosure positioned transversely to the axial enclosure, which may or may not be watertight. These enclosures are preferably configured with the upper surfaces of their covers at a single level, for use collectively as an extended, relatively flat fishing seat.

A collapsible watercraft is comprised of a single high-strength foldable panel to fold into the form of a kayak with integrally defined keel, hull, sides, and deck. Using a single sheet of high strength panel creased in a predetermined pattern to form living hinges, the panel may be folded and transformed from self-defined compact knocked down package, into a rigid three dimensional tubular manifold in a kayak form that is optimized for performance in the water. Other removable rigid structural members, primarily a cockpit rim, rib, and floorboards help maintain the shape and integrity of the shell.

Canoe and kayak mid-point sponsons attach to the canoe or kayak only at the mid-point of the sponsons, to enable the sponsons to rotate around the midpoint in order to reduce drag in waves and simplify attachment and detachment to the canoe or kayak, while also permitting much greater sponson buoyancy volume than any other type of sponson, without interfering with normal paddling to safety. They are attached to any canoe or kayak by material such as only one adjustable strap and two clips, extending to kayak deck fittings adjacent the cockpit or a canoe middle thwart, in such a manner as to facilitate normal paddling of the stabilized craft in life threatening emergencies. They can be directly attached to both sides of the hull near the waterline. The mid-point sponsons can be solid buoyant material, waterproof and airtight stowage bags containing bulky lightweight items such as sleeping bags, orally inflatable sponson floats, and gas cartridge inflatable sponson floats. A particular feature is permanent or semi-permanent attachment to the hull above the waterline to eliminate drag unless inflated, in which case the inflated sponsons are forced to immerse in the water. When not inflated each midpoint sponson would be neatly stowed in a small and rescue-emergency marked stowage bag or covering that holds sponsons upward from the waterline. Such an arrangement ensures that the sponsons rest sleekly and unobtrusively along the hull side when not deployed.

A seating system for use in a watercraft is disclosed. The seating system comprises a seat pan adapted to be mounted to the watercraft, a pad coupled to the seat pan and adapted to provide a seating surface for the user, and a back rest coupled to the seat pan.

The present invention introduces a small boat (kayak or hybrid kayak-canoe) made in a plurality of nesting sections. It is covered with a waterproof fabric cover, incorporating a stabilizing and flexible keel sewn into it. The boat also has a releasably attachable and flexible coaming.

The invention is a portable collapsible boat comprising one or more rigid cockpit sections, constructed of a material such as fiberglass, attached to a bow section and a stem section, which are constructed of fabric material covering a skeleton of longitudinal stringers and ring frames, and are attached to the rigid cockpit section(s) by means of a belt, buckles, and / or flanges. The hybrid folding boat combines the best features of rigid boats, such as performance and durability, with the best features of existing folding boats, such as transportability, without suffering from the drawbacks of rigid boats (mainly the extensive storage space required) or folding boats (mainly weight). The hybrid folding boat is lighter, easier to transport, more rugged, safer, easier to assemble, and stiffer than previous folding boats, adapts easily to a sailing rig, and facilitates one or more passengers. Manufacture of the boat is simpler than that of conventional folding kayaks because it has fewer parts and less dependence on precision stitching of the fabric covering.

A personal boat carrying apparatus is provided for supporting a kayak or similar boat on a user during a portage to make portaging a kayak easier and less uncomfortable.

Each body end has a support arm which pivots from a closed position to one or more open positions. The pivoting support arm provides multiple open positions to allow the apparatus to support kayaks and similar boats of different widths and configurations. Each support may have a swiveling bracket for engaging the gunwale of the cockpit of the kayak or similar boat. When the support arms are in the closed position, the apparatus may be compactly stored in the boat or elsewhere.

A pedal-powered kayak, the present invention offers a more rounded keel and stem which operates in the water leaving no or little wake in the front or the rear of the boat.

The kayak has a topside axial enclosure, which may be rendered watertight and used as a bait tank or other liquid container, and at least one additional enclosure positioned transversely to the axial enclosure, which may or may not be watertight. In the preferred embodiment, a second additional enclosure is positioned transversely to the axial enclosure on the opposite side from the first additional enclosure. The enclosures are preferably configured with the upper surfaces of their covers at a single level, so that they may be used collectively as an extended, relatively flat fishing seat. Various access and sealing means are selectively provided for the respective enclosures. For example, a removable transparent access port may be included within the cover of the axial enclosure. In some embodiments, a circulation pump is provided to discharge within the axial enclosure. Likewise, the transversely positioned enclosure(s) may be selectively removable. In some embodiments, those enclosures may, upon removal, expose an opening to the kayak's internal cargo hatch.
