It depends on how you use an inflatable boat. A boat that’s used once a year won’t hold up as well as one that’s being used multiple times every summer. Most manufacturers suggest that inflatable boats be cleaned and inspected before each use, which will extend their lifespan even further. If an inflatable is maintained correctly, it can last for years with little to no wear and tear.
While some materials naturally degrade over time (like PVC or rubber), most inflatables have been treated with UV inhibitors to extend their lives outdoors. Of course, there are exceptions—an inflatable may begin losing air slowly because of a puncture wound, but overall, inflatables are incredibly durable!
Just remember: if your vessel starts developing slow leaks, do not patch them yourself mediately. Better to contact your manufacturer so they can guide you on how to replace any parts that are damaged beyond repair.
Average 10-15 years, but it’s all about conditions. For example, If used almost daily for things like water skiing, wakeboarding, and other sports activities, it will go less up to 10 years and can be less. It will lose air slowly through punctures and damage, but that is normal and expected for most inflatables, even new ones. Cheaper models are lighter weight fabric with minimal thickness—around half-inch thick—and they aren’t meant to be for a long service without tearing or stretching out of shape.
