To provide an emergency/life boat capable of easily performing action/activity for emergency/life/rescue in a flood accident or the like in a swimming beach, river, lake or the like.

In the emergency/life boat, left and right floats are low floors and avoid a wind pressure. A bottom part is a flat surface and avoids a tidal current. The float of an oar part is removed, a water pressure is weakened and the oar part is sunk in water. A flood victim is easily pulled up to the boat and is fastened and protected with an emergency/life belt. A wave guard and a wind guard are installed on the head of the flood victim. A rotary screw is provided on a boat bottom and it is activated, rotated and operated by manual operation of a life server. Kicking force of an attached fin worn by a life saver ranger member is added to accelerate returning to the port. Further, a wave cutting part of the bow is automatically raised for preventing water-intrusion at towing by the other boat to enable smooth towing.
