It doesn't matter how they are made, whatever their shape, colour or configuration is, all of that is superfluous. The only "real" comparison is how well they perform against each other around the race course. Nothing else really amounts to a "hill of beans", and to offer up “reasons” sounds instead, more like “sour grapes” and excuses.
P.S. We have beaten every A class cat that we have sailed against over the line in 3 out of every 4 races that we have had with them over the last 12 months on a (lowly) F14. Does that make us the most technologically advanced and fastest single handed cat in the world today???
