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.
