Rescue apparatus for rescuing a person in water has a body with inflatable pontoons interconnected by upper and lower frames to provide an opening between the pontoons to receive the person. Thrusters cooperate with the lower frame below the surface, and receive power and control signals to control movement of the apparatus on the surface. A net enclosure encloses the pontoons and frames and has an opening adjacent one end to receive the person. The upper portion of the apparatus is lighter than the lower portion, preferably by having the upper frames inflatable, to provide a low center of gravity for self-righting if the apparatus becomes inadvertently inverted. The lower frame can include two generally U-shaped frame members which are shaped to fit one within the other to reduce storage volume of the collapsed apparatus when the pontoons are deflated. The apparatus is designed for storage within a helicopter, and can be retrieved from the water by a helicopter with a lifting line positioned so as to permit relatively easy unloading of the person from the apparatus into the helicopter. The apparatus can be used also from ships, oil drilling rigs etc.
