Abstract

An inflatable life raft which forms a passenger receptacle, has a removable canopy for covering the passenger receptacle and is formed from a flexible walled housing which includes inner and outer walls, with a plurality of chambers being formed between the walls. A bleeder mechanism, in the form of a plurality of cords disposed in the chambers keep substantially all of the areas of the chambers in communication with each other so that inflation and more especially deflation, can be readily accomplished without forming air pockets caused by the inner and outer chamber walls sticking together precluding the free flow of air.
