That depends on what area you are using, like the rubber dinghy I used for 4 years at most.

The reality is gone. The products made in China are much better than before. But there is still much to improve. The military might last a little longer, but it's too heavy... The main factor affecting the life of rubber dinghy is ultraviolet light. Therefore, the main way to extend life is to protect against ultraviolet rays.

One is in the PVC boat production process, PVC material has added uv - resistant material.

Two it is to use in prevent ultraviolet ray, abroad houseboat dock, RIB boat is put dock for a long time, must use prevent ultraviolet ray ship cover, brush regularly prevent ultraviolet maintain oil and so on (take from PVC boat user manual) this kind of circumstance falls, can use 10 years long.

For example, we play speedboat, do not do commercial use, just occasionally enter the water, a year can not add up to a month. Life should be longer if punctures and scratches are excluded.

Of course, it is better to pay attention to maintenance:

Pay attention to the air pressure, do not overcharge the air, gas will heat up cold contraction, exposed to greater air pressure; Air chamber pressure to be balanced;

After playing, wash and dry fresh water to avoid frequent folding because of fatigue at creases.

It can be stored in conditions of 60-70%, which is more advantageous and can prevent the rats from biting.

Avoid contact with corrosive liquid. Clean gasoline and diesel with neutral detergent. This basically still sees you to use circumstance, with maintain circumstance, have again the material that you buy is how, use a few years to be no problem.

Also, the brand and material of rubber dinghy are quite particular. If it is the product of general miscellaneous brands or nameless small factories, it will have a great impact on the life. Therefore, it is suggested to choose some well-known brands.
