The present invention involves an inflatable life raft for use in an aircraft. The life raft comprises an air providing device, a floor, a buoyancy tube, and a canopy. The buoyancy tube is disposed about the floor. The canopy protects survivors located on the floor, and includes a cover and an inflatable support having at least three inflatable legs attached to the buoyancy tube. The air providing device inflates the buoyancy tube and the inflatable support. The canopy cover may be positioned in at least three arrangements: a closed position, a sailing position, and a convertible position. The two layered canopy cover includes two zippered doors allowing for ingress and egress, and has a plurality of radar reflective portions. The floor has a generally round shape or a polygonal shape with at least ten sides. A second buoyancy tube is disposed on the first buoyancy tube, and both have approximately the same size. The floor comprises an insulated double floor, and is attached to a plurality of ballast bags disposed around to the outer under perimeter of the floor for stabilizing the life raft in water. A sea anchor is coupled to the lower buoyancy tube by an adjustable swiveled line. A grab handle is attached to the buoyancy tube. The floor comprises an upper floor, a lower floor, and a plurality of reeds defining a buoyancy chamber. A righting line with hand grips is mounted on the underside of the floor so that when the life raft is inflated upside down in the water, a survivor may grasp the righting line and right the life raft.
