ABSTRACT:
A self-righting inflatable life raft including a raft body having inflatable sidewalls and an inflatable member extending from the raft body having a buoyant portion sufficient to provide lifting force to move the raft's center of gravity beyond its point of rotation on the surface of water such that the raft will topple by gravity to an upright position. The inflatable member may include a plurality of inflatable tube portions which extend from an upper edge of the raft sidewalls to a first predetermined position upwardly and outboard from the upper edge and which then extend inboard to centrally converge with one another at a second predetermined position above the raft body.
