Hi, I'm a heavy sailor, weigh 20lb. I know it is difficult for heavy sailer to sail laser faster than light weight sailors of 15lb or so, if skill level is same. I just want to do everything I can do, parallely reducing weight. I could catch up with light sailors in downwind. ( I'm not sure why). But in upwind I found my boat speed is rather slow in light air. My upwind set in light air (1 to 5 knots) and smooth water is, Vang : loose, outhaul loose (distance between boom cleat to sail foot : 30cm), mainsheet : distance between blocks: 30 to 40 cm, Cunningham : completely loose, Sit position : on mainsheet cleat. I will aprreciate your any advice, specially from heavy sailors.TKS
