Anyway, I find the f18 crews generally more aggressive. In my experience there are more skippers there willing to push the rules a little bit to gain any advantage, especially if it is just fouling an irrelevant boat from some other class they are not directly competing against. To make matter worse, due to their minimum weight, those boats are overbuild and build like tanks. A side sweep by one of those is going to cut any F16 in two. I would not take the risk.
