We all know that the manufacturers could build their boats at 165kg if they really wanted to, but profit margins reign.
Hi Marcus
I don't believe it has anything to do with profit margins. The Formula was born from the Hawk and Tiger, both built at 180 kg. Builders today could build them lighter, very easily but they have a sucessfull class going at the moment and would put that at serious risk if they decided to knock 15 to 20kg off them.
The A class also can be built with ease now, down to 70kg..... But the class also does not wish to damage their sucessfull fleet. It would be a hell of a lot easier and less damaging too introduce it into the A Class, than the F18.
