Abstract: A kayak safety buoyancy stirrup consisting of an adjustable stirrup and an inflatable buoyancy bag flexibly attached to the deck of a kayak: carried on the deck of the kayak and permitting immediate deployment by a kayaker in the water, on either side of the kayak. The buoyancy stirrup has sufficient buoyancy to allow a disabled kayaker to step out of the water immediately to prevent hypothermia and lie across the device and the kayak deck in extreme emergencies, a foot in the stirrup and hands and arms entwined in kayak deck rigging, preventing the kayaker from falling into cold water again. The inflatable buoyancy bag has an air-tight closure mechanism to permit stow-age of bulky, lightweight items. Pouches containing safety equipment such as kayak safety sponsons may be attached to the bag to organize and prevent forgetting of vital safety equipment.

Abstract: Kayak safety sponsons having two parallel inflatable tubes along the waterline on each side of the kayak adjacent the cockpit. These tubes join together below the waterline by means of material such as straps and above the waterline at both ends by a fastener such as a strap with a quick-release buckle, at each end of the cockpit. They can be attached and inflated by the kayaker seated in the cockpit while using a paddle. Deflated, the sponsons are flat and tightly drawn against the hull by the two fasteners for minimal water resistance. Inflated, the sponsons taper toward both ends for minimal water resistance, increasing maximum waterline beam of the kayak adjacent to the cockpit area but not affecting foreward and aft lines of the craft, permitting normal handling due to minimal change in underwaterlines and minimal increase in water resistance.

Abstract: Folding kayak cover provides storage access to the full length of the kayak interior by means of the same fasteners attached to the cover which stretch the cover transversely and longitudinally over the assembled, non-expanding frame, which has a deck ridge. These fasteners, comprising lengths of material such as straps with buckles or lacing, are spaced in two sets, along the full length of the deck where the cover overlaps, sandwiching a compressible gasket at the deck ridge and making a watertight seal. One set of fasteners release the overlapping part of the cover along the full length of the deck to expose for storage the openings between the fasteners of the other set which connect the underlying edge of the cover, on the deck ridge, to the non-overlapping part of the cover next to the nearest gunwale.
