I am pleased that the BOG will change the mainsail materials but the weight restriction of 30# is unsatisfactory. A tape sail will weigh much less and THAT is the whole point of using them. Performance. If as some say there is no real benefit to the light sails then what is the problem with the light materisls. I want to be competitive in PHRF. that is where I sail. I am still buying my next main as LPT Mylar around 25# worth , less if it happens that way.
