The spreader height(single spreader rig) is too low for the long foot of the sail. I played around with different locations on the boom but moving the pad eyes aft decreases the angle. There simply isn't any way to contain the aft 4-5 feet of the sail and lower batten. The only solution is to go up to increase the angle effectively while moving the aft strap eye out. I don't see any downside, yet.
