Question

When not in use should a inflatable boat be inflated or not.?

Answer 1

I would deflate it to reduce stress on the boat and prevent the material from springing leaks.

Answer 2

I am getting a 3 metre plus inflatable. I intend to store it inflated but not to full pressure. Not sure if this is the commonly accepted way but to my mind it will keep its shape and avoid unecessary creases which may otherwise occur if stored deflated. Not having it at full pressure will eliminate undue stresses on seams and fittings.
