A good friend of mine (wheelchair bound)asked me to help him store his Hobie 16 for the winter. We have no choice but to leave the hulls and tramp. outside and he told me that that trampoline has to be slackened a bit for the winter but he doesn't know how much. I'm sure that this would allow for contraction of the material in the cold weather so I'd like to know "How much slack should I give to the trampoline?"

Thanks for your help.
