Canoe and kayak mid-point sponsors attach to the canoe or kayak only at the mid-point of the sponsors, to enable the sponsors to rotate around the midpoint in order to reduce drag in waves and simplify attachment and detachment to the canoe or kayak. They create greater sponsor buoyancy and stability than any other type of sponsor , 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 sponsors can be solid buoyant material, waterproof and airtight stowage bags containing bulk y lightweight items such as sleeping bags, orally inflatable sponsor floats, and gas cartridge inflatable sponsor 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 sponsors are forced to immerse in the water. When not inflated each midpoint sponsor is neatly stow ed in a small and rescue-emergency marked stowage bag or covering that holds sponsors upward from the waterline. Such an arrangement ensures that the sponsors rest sleekly and unobtrusively along the hull side when not deployed.
