A life raft having a flotation platform including a peripheral buoyant member and a flexible floor spanning the buoyant member is provided with a stabilization chamber located beneath the flotation platform which fills with water when the life raft is deployed. A bailing chamber is located between the stabilization chamber and the flotation platform and receives water from the flexible floor and exhausts water from the bailing chamber in response to pressure exerted on the bailing chamber by wave action, so that the life raft is made self bailing by wave action. The raft may have a flexible diaphragm attached to it defining an air pump chamber and connected to a conduit extending upwardly through which air can be drawn into the air pump chamber. A weighted chamber depends from the flexible diaphragm and fills with water when the raft is deployed, to exert a force on the diaphragm increasing the volume of the air pump chamber in response to upward motion of the raft. A check valve allows air to pass from the air pump chamber into the buoyant member in response to submerging motion of the raft. This renders the raft self inflating by wave action. |
