Self righting inflatable life raft is an advanced marine life-saving equipment. It has the function of automatic centering after inflation and expansion. When a life raft capsizes in water due to factors such as wind and waves, it can rely on its own design and structural characteristics to automatically return to a positive floating state in a relatively short period of time. The principle is mainly achieved through reasonable weight distribution and raft shape design. The bottom of the raft usually has heavy ballast or special buoyancy compartments distributed, which can generate a moment that causes the raft to flip back to the upright position after overturning due to the interaction between the center of gravity and the center of buoyancy.
