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.

An adjustable buoyancy system for attachment to a kayak having a cockpit comprising: a pair of tapered buoyancy tubes extending along the waterline, one on each side of said kayak, said buoyancy tubes having a length approximately the length of said cockpit of said kayak, a first connecting means extending between said pair of buoyancy tubes adapted to extend under said kayak, a second connecting means extending between said buoyancy tubes and adapted to extend over said kayak, said second connecting means including attachment means to facilitate attachment and removal of said buoyancy tubes from said kayak, and a pair of inflation tubes, one attached to each of said buoyancy tubes, said inflation tubes having a length sufficient to reach the user seated in said cockpit to allow the user to inflate said buoyancy tubes from a non-inflated condition with said buoyancy tubes lying flat against said kayak, to an inflated condition to stabilize said kayak.
