Topping lift is eased and slack so boom is loaded by sail and main sheet only. The jib sheets run through blocks that are on track slides so I can adjust sheet angle. I have made adjustments of the block slide with no real change of the flapping. Also changing jib sheet tension cannot get rid of the flapping. Even with the jib reefed and sheeted in tight I still get a flapping.
