The three Laser rigs are NOT raced as one design. No attempt is made to balance the weight for single-class racing.
Of course not, because they are racing one-design within each class, which is already balanced out for weight by having the same sails in each weight class.
When you get up to the full-sail Laser rig, then the sailors themselves balance out their own weight. I can tell you that the top sailors keep themselves on very strict diet and exercise regimes to stay within the optimum weight for success.
How many catamaran sailors want to be that self-disciplined just for fun? Those Olympic Laser guys live on stuff that looks a lot like dog food.
