Who knows? We've certainly seen a lot of classes come and go - but have we seen a class explode like F18 in the past? My point is that the rule seems to fit the bill for a lot of people. I don't have any trouble moving my boat around on shore and speed, for me, is relative. Hell, I REALLY enjoy racing Waves as long as there is a tough fleet (if you haven't tried it - you should!). F18HT's were light and probably faster (?) but that didn't shake out real well. Class health is not necessarily measured by boat weight and overall speed.
