ABSTRACT:
A rescue raft that includes a buoyant, elongated floor and a pair of parallel air chambers or pontoons on each side thereof is disclosed. Together, the floor and the parallel flotation members possess sufficient buoyancy to prevent the raft and a victim thereon from sinking. The raft also includes series of graspable members, extending across the floor and distributed sequentially along its longitudinal extent, that facilitate a victim's entry onto the raft and, when oriented vertically, form a ladder that assists entry onto a rescue boat. In a first embodiment, the graspable members are a series of cut-out windows through the raft floor. In a second embodiment, similar windows are formed by transverse inflatable rungs secured to the parallel air chambers. In a third embodiment, the windows are replaced with buoyant segments or cushions that project from the floor. And in a fourth embodiment, the graspable members are straps that extend transversely across the floor, at least some of which may be drawn around the victim.
