A rescue net characterized by a base ring, a rail ring, netting covering the base ring and extending between the base ring and rail ring, a hoist assembly, and a number of shroud lines coupling the rail ring to the hoist assembly. The base ring and the rail ring are provided with a number of holes so that they flood and sink upon contact with the water. This allows boating accident victims and the like to be scooped out of the water by lowering the net from a helicopter and dragging the net below the surface of the water towards the victim.
