Description

Technical Field

[0001] The utility model relates to the technical field of ship engineering, in particular to a lifeboat. Background Art

[0002] Existing small lifeboats mainly include rubber boats and assault boats. The main disadvantages of rubber boats include poor stability, poor wind and wave resistance, poor rollover resistance, insufficient load capacity, easy puncture and difficulty in maneuvering. The material and design features of rubber boats determine some of their limitations in water activities. Rubber boats are usually lightweight and easy to carry and install, but this lightness also brings the problem of poor stability. Because rubber boats have a shallow draft, most of the hull floats on the water surface, with a large wind-exposed area, and can easily be blown away from the shore. Especially in the face of strong winds and waves, their wind and wave resistance and rollover resistance are relatively weak, and their safety is not high. In addition, due to the material, the load capacity of rubber boats is limited, making them unsuitable for carrying heavy cargo or multiple people. Easy puncture is also a significant disadvantage of rubber boats, especially when facing sharp objects. The weak material is easily punctured, which affects their use. The difficulty in maneuvering is because the rubber boat may produce irregular movements in the water due to the influence of the water flow. For beginners, it may be difficult to control such a boat.

[0003] Fiberglass assault boats are sturdy, but relatively large and heavy, making them inconvenient to carry, transport, and get on and off the water. Due to their weight, fiberglass assault boats must be equipped with larger outboard motors, which increases costs. Furthermore, their heavy weight requires a more powerful engine, which indirectly increases operating costs. They are not maneuverable enough: Fiberglass assault boats are heavy and bulky, making them less maneuverable and difficult to load, unload, and store. They lack folding wheels, paddles, or life ladders, and therefore have fewer features. Consequently, they are heavy, costly, and lack maneuverability and functionality. Utility Model Content
