I've also recently purchased a Ross 830 (Flaming Lips) and have two questions. The First is that the boat came with a square top, the bottom three battens being half length and the top 3 full length. When sailing up wind as soon as any backstay tension is added and even without any backstay at times the main starts to "fold" at the front of the half lenght battens. Does anyone have any suggestions on how best to trim the main to avoid this, or is it a matter of getting full length battens? (we have fractional runners for forestay tension and these are always on going upwind). My second questio
