I am not sure that "argument within the class" between solo sailors and crewed boats will cause problems Matt, healthy competition within a class like that is most time good for the class and gets more sailors out on the water to "compete" against each other in both configurations, BUT when it becomes an argument outside the "class" due to unjustifiable or ambiguous ratings, thats a differnt ball game. (United we stand against the world - even though we may fight like cats and dogs within the family, what happens at home should stay at home)
