In order to overcome the possible overturning of inflatable life rafts in the process of sea formation, avoid the difficulty of personnel launching and righting the raft, and meet the needs of survival personnel at sea for safety and rapid response, some manufacturers have developed inflatable self-righting life rafts. Once such life rafts are overturned on the sea surface during the deployment process, because the top of the raft is circular, the contact surface with the water can be reduced, and the sum of the weight of the raft body and accessories can make its center of gravity at the bottom of the life raft. After the life raft is inflated and formed, it can be self-righted.

There are two types of deployment of inflatable life rafts, namely, mechanical lifting and throwing. The mechanically suspended raft has been inflated before entering the water; Throwing liferafts are inflated and formed on the sea surface. During the process of inflatable forming, the liferafts may be overturned, so they need to be manually launched and straightened before they can be used for boarding.
