PURPOSE: A lifeboat for life protection is provided to safely rescue survivors with an on-off rescue gate part and to quickly rescue the survivors by charging a reinforcing member and a material for the lateral side of a lifeboat. CONSTITUTION: A lifeboat for life protection comprises side parts, a W-shaped bottom part(700), and a rescue gate part(300). A foaming agent is charged in the side parts to prevent the outflow of air. The W-shaped bottom part increases the speed of the lifeboat and improves safety. The rescue gate part has an on-off plate at the center of a stem to rescue.
