The rescue system includes a mobile trailer on which are mounted telescoping hydraulic arms and a winch. A net is connected to the winch and passes over a roller mounted at the outer ends of the hydraulic arms which are vertically and horizontally movable to position the net over the body of water. The net hangs downwardly from the roller into the body of water. A ballast is attached at the lower end of the net so that the net is vertically oriented in the water. A rope connected to the lower end of the net and a set of pulleys enable the lower end of the net to be lifted to envelope a person therein. When the person is enveloped in the net, the winch is actuated via an electric motor to reel in the net and lift the net and the person out of the body of water and to a place of safety.
