Sorry Stuart, I was never invited to give any input when the class was being developed and I doupt Macca was also. I am also sure the other class's you mentioned above would also share simular views on the subjects we raised. They have elected to be very development driven class's and accept the costs assosiated with it. The F16 class wants to be a formula class, very open to development but does not accept this would drive the boats up dramatically in price if the class becomes competitive enough and stakes high enough to warrant.
