True.
It's also true that lighter boats are a hell of a lot more 1) practical and more importantly 2) handle that much better. That's why I'd tend to go for the Falcon over the heavier Viper (speed is not an issue between the two designs as AHPC has proven that the heavier boat can keep up).
So from a purely business standpoint it makes since that AHPC would want to raise the class minimum weight as they lack two important selling points over their competitors.
Also interesting to me how the Aussies have moved production overseas while the Americans and Europeans seem to still be able to manufacture lighter boats and be competitive. Funny but somehow I assumed that cost of production was actually lower in AUS then it was in let's say the US or Europe so I do really need to update my economic reference points for these new modern times..
