But I must add that the accusation of the conspiracy was a bit tongue in cheek.
The reasons for the weight difference between Viper and other boats is purely economical in my opinion and having a 120 kg (homebuild) F16 myself I know how competitive you can still be at that weight. The F16 don't appear to be very weight sensitive.
