Neither - upended against the wall standing on the leech end so you don't make the luff tube go soft which reduces resale value (as it looks more used than it really is)
But I'm sure it really does not matter.........
Make the luff tube go soft...what? I've never seen a sail where the luff tube isn't soft...it is after all like that for a reason. Logic would dictate that if you are going to store your sail vertically you want to store it so the load is most evenly distributed, this means sitting the luff on the floor as it rolls quite uniformly. Conversely if you stand it on the leech end it's more than likely standing simply on the very clew of the sail, poor load distribution and not really a part of the sail you want to bend.
Other than that I can't see how standing it or lying it would make any difference. I always stand the sail i've just used in the garage so all the water runs out of it gravity stylez, then back in the rack it goes.
