SCHRS for example mercilessly penalises light boats ( such as the A's and single handed F16's ) where I feel most of the future classes are being established from. Any boat that is both light, single handed and has a jib has absolutely no chance to be able to perform to its handicap. The F16 class is a point in case under SCHRS with the single hander having a faster handicap than both F18 or Hurricane 5.9 which in reality is never going to be the case on the water.

On the other hand if your boats are heavy ( such as the F18 and Hurricane 5.9 ) by class rules, but have well developed modern high aspect sails with bouyant hulls to match then you are onto a winner and SCHRS is your baby.
