Existing amphibious boats cannot pass smoothly when they reach the junction of the ice and snow road surface and the water surface (floating ice area); 3. The overall weight of the existing amphibious boats is relatively large, which makes them have great resistance and slow speed when traveling in water. Summary of the invention
