ABSTRACT:
A buoyant collar is stored in a biased condition around the top outside of a boat hull. Should the boat overturn the buoyancy of the collar will work against the biasing and allow the collar, still attached to the boat, to float to the surface and provide a hand hold for the persons in the water.
