It depends on the area you're in, like the rubber boat I used for four years at most.

　　The reality is not. The products made in China are much stronger than before. But there is much to improve. Military ones last longer, but they're too heavy... The main factor affecting the life of rubber boats is ultraviolet light. Therefore, the main means of extending life is to prevent ultraviolet radiation.

　　One is in the production process of PVC boats, PVC materials have added ultraviolet resistant materials.

　　The second is the use of uv protection, foreign yacht wharf, RIB boat long-term put wharf, must use uv protection cover cover, regular brush anti-uv maintenance oil and so on (extracted from the PVC boat user's manual) this case, can be used for 10 years.

　　Like we play speedboat, do not do commercial purposes, only occasionally into the water, a year added up to play less than a month. Life should be longer if piercings and scratches are excluded.

　　Of course, usually pay attention to maintenance is better:

　　Pay attention to the air pressure, do not inflate too much, the gas will heat up and cool down, after exposure to the sun more pressure; Chamber pressure must be balanced;

　　After playing, fresh water washed and dried, to avoid frequent folding, because the crease will fatigue;

　　Conditional inflation 60-70% storage, inflation storage benefits, but also can prevent rat bite;

　　Avoid contact with corrosive liquids, gasoline and diesel with neutral detergent cleaning. This basically still depends on your use circumstance, with maintain a circumstance, have even if the material that you buy is qualitative how, with a few years no problem.

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