We are proud of our boats and fenders.  We back them with a 5-year warranty for any manufacturing defects.  We use common sense for our warranty.  What does that mean?  Things like tying an inflatable to a dock with 1 line in a hurricane is not supported by common sense. 

A note about boats and the tube fabric options.  PVC does not hold up well in the intense tropical sun of southern climates and the life of the tubes will be much shorter than you would have in a northern climate.  We do not warranty the PVC tubes in southern climates.  We carry Hypalon fabric tubes for those climates and those tubes come with a 10-year warranty for any climate.
