I hang up my sails if they aren't going to be used for a while, or if they were put away wet, I like to hang them up in the basement so they are completly dry.
I roll from the bottom up, and still have to pull the top batten. Even removing the 2nd from the top would be nice to get a tighter package.
Its kinda nice having a unfinished basement. I almost don't want to finish it, its nice having a safe, warm, and dry spot for the boat in the winter. Tough to see in the pic, but the main is just behind the spin hanging away from the wall.
