Like FLAME said above, store them on sawhorses. I have some old fold-up plastic Stanley saw horses.
However, after the first season, I found my canoe and my jon boat both floating right-side-up on the other side of the pond after an overnight thunderstorm. I installed four dog-leash anchors near where I put the saw horses.
I screwed them into the ground so that there is well less than an inch sticking above the grass -- otherwise they have a way of dulling my lawnmower blades.
I bought some cheap cargo straps to go over the boat or canoe that I connect to the dog anchors to keep them from flying off during high winds.
When I figure my jon boat isn't going to be used for several weeks or more, like during the winter, I get somebody to help me turn it upside down on its trailer.
Right now, it is time to go hook the jon boat and trailer to the truck and take it to a local lake that re-stocked with trout yesterday for the last time this season, and where there is a good crappie bite reported.
