The inflatable boat is small in size, and the propeller is added at the stern, which can significantly improve the navigation speed. It is widely used in water recreation, entertainment, fishing, fishing and other water operations. Generally speaking, the inflatable buoyancy tyre of the whole boat is divided into several independent air chambers, with high air tightness. When individual air chambers are damaged, other parts still maintain enough buoyancy. When two or more adjacent air chambers are damaged at the same time, the whole boat still has some buoyancy.
