I don't have a stock sail, and cannot hoist it solo on the water. Flipped once when reaching to pulland cleat downhaul. Caught a puff and the boat went over. While righting it, the main came unhooked without the downhaul pressure to hold it. Had to have a friend help me. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
