Less batten tension. No downhaul at all. If it is going to be light for a while, replace the top 3 or 4 battens with something thinner--you can get pultruded epoxy rods at tap plastic. And here's a tip...in light breeze hold the mainsail clew by hand and pull it toward you on the windward side as far outboard as you can. You want as much twist in the mainsail as you can get. If it is too hard to hold by hand, tie a line to the traveler and pull it up windward as much as you can. If there are others on board have them sit leeward to try to get the boat leaning and help drape the sail using gravity (alternatively, have them jump off and tow the boat).
