It depends on what area you use, like the rubber boat I used for up to four years.

　　The reality is gone. The products made in China are much stronger than before. But there is still room for improvement. Military use lasts longer, but it's too heavy... The main factor affecting the life of rubber boats is ultraviolet radiation. Therefore, the main way to prolong life is to prevent ultraviolet radiation.

　　First, in the production process of PVC boats, PVC materials are added with ultraviolet resistant materials.

　　Second, the use of UV protection, foreign yacht wharf, RIB boat long-term dock, must be covered with UV shield, regular brushing of UV protection maintenance oil (extracted from the PVC boat user manual) in this case, can be used for 10 years.

　　For example, when we play stormboat, we don't use it for commercial purposes, but occasionally go into the water. Together, we can't play for a month in a year. If punctures and scratches are excluded, life expectancy should be longer.

　　Of course, it is better to pay attention to maintenance at ordinary times:

　　Pay attention to the air pressure, do not inflate too much, the gas will heat up and shrink, the air pressure will be higher after exposure; the air chamber pressure should be balanced;

　　After playing, freshwater is washed and dried to avoid folding frequently, because the creases will be fatigued.

　　Conditionally inflated 60-70% storage, inflated storage benefits, but also anti-rat bite;

　　Avoid contact with corrosive liquids. Clean gasoline and diesel with neutral detergent. This mainly depends on your use and maintenance, and what kind of material you buy, it's OK to use it for a few years.

　　There are also rubber boat brand and material is also very particular, if it is general miscellaneous brand manufacturers or nameless small factory products will have a great impact on life, so it is recommended to choose some well-known brands, although the price is more expensive, but durability and safety are guaranteed.
