Abstract: An aquastabilized survival raft comprising a buoyant inflatable structure circumscribing a floor. A stabilizing chamber is attached to the underside of the buoyant structure. The chamber comprises at least one orifice in the lower portion thereof and a plurality of apertures in spaced locations around the upper periphery extending from the interior of the chamber to the atmosphere. When placed upon a body of water, water rapidly fills the stabilizing chamber by entering the orifice and expelling air through the apertures. The water-filled chamber stabilizes the survival raft so as to minimize pitching and rolling in rough water. An inflatable water-tight hemispherical shelter having suitable openings therein is attached to the top of the buoyant structure and when inflated protects survivors against the elements.
