Why does everyone see it as such a detriment to their class? I think it's clear that if they were to go with an F18 or an A-cat that it would be a SMOD from within that Formula rule that if it didn't evolve might become sort-of irrelevant, or at least semi-distant, to the class as hull shapes and foils evolve elsewhere.
With the Hobie 16 - I don't understand the hesitation...if the class was controlled within the existing (and very unchanging) ruleset as a SMOD - what's the drawback? More high-end competition?
Is it fear of an arms race? How many times have we heard threat of that issue that never came to fruition?
