Your right the heavier crews do well in that stuff, but once again the single handed guys are greatly hindered in that wind. I bleieve those rules are similar to the A cat rules and make a lot of sense. It gives the PRO something to go by if the conditions are iffy. If the tornados have a rule for upper wind and those are 20 foot long 10 feet wide boats with some of the best sailors in the world, should we not take heed and follow somwewhat adjusting for the difference in boats.
