So remove the weight limit, let everyone find a compromise between weight, quality, stiffness, performance.. The Viper won't change. I predict the boats will get heavier and stronger and hence faster. Unless your willing to spend real $$$'s.
F16 is a development class, go for it...
I think that the above statement is a very valid one and one that time will prove. With the technologies available the 100 kilo boat is very feasible but to achieve that weight the boat will be smaller in all areas including hull volumes and beams and hence will not be as stiff and will sit lower in the water ( drag ). That balance between stiffness, hull volume and economy of build will be the leveller in performance and for me that is a really good thing as it will allow the heavier boats such as the Viper to compete equally with the more exotically built lighter boats.
As to taking the min weight rule away all together, to thornier subject to even contemplate for a few years I'm afraid.
