The invention discloses an overwater fast life-saving system. The system comprises an overwater fast life-saving device, multiple signal receivers, a controller and multiple automatic life-saving equipment releasing devices, wherein the overwater fast life-saving device is worn on the body of a person on a boat and used for transmitting wireless signals through a wireless signal transmitter in the device when the wearer falls into water; the multiple signal receivers are distributed around a boat body and used for receiving the wireless signals respectively, acquiring corresponding RSSI (received signal strength indication) values and transmitting the values to the controller; the controller is used for acquiring the value of the distance between the overwater fast life-saving device and each signal receiver according to the corresponding RSSI value so as to acquire the direction of the person falling into water, acquire the automatic life-saving equipment releasing device nearest to the person falling into water and transmits a control signal to the nearest automatic life-saving equipment releasing device; the multiple automatic life-saving equipment releasing devices are distributed around the boat body and used for releasing life-saving equipment in the automatic life-saving equipment releasing devices into water according to control signals. With the adoption of the system, the direction of the person falling into water can be acquired rapidly, and the life-saving equipment can be released rapidly, so that the person falling into water can be saved timely.
