During the voyage of ocean-going vessels, lifeboats and other life-saving types of equipment are the survival of the crews. At present, there is still a lot of room for improvement in the structure of lifeboats, supporting facilities, production materials, ease of operation, etc. The article summarizes the development history of lifeboats and their slip trajectories based on the development of ocean-going vessels. The article summarizes the shortcomings of the lifeboat and its sliding trajectory based on the development history of ocean-going shipborne lifeboats and proposes the use of 3D printing technology to carry out the model printing of the lifeboat and ancillary facilities, and the use of the printed model to carry out experiments repeatedly to explore, and to find a way to make the boat from the high altitude to reach the surface of the water caused by the smallest impact effect of the angle, which greatly reduces the impact of the lifeboat into the water. The impact force of the lifeboat into the water is greatly reduced. The aim is to improve the survivability of ocean-going vessels at sea and increase the chances of survival of the crew.
