I don't know - I actually put that suggestion about the factory to Greg in an email a while back and he was very clear that that was not the issue at all. You've pointed out elsewhere yourself that the hulls are only 3kg more than the Blade and clearly there has to be a hit for the extra volume.

The reply Bob got also highlighted the significance of the target crew weight in the overall design. If it's true that this is part of the justification for greater volume, I think he may be more concerned about putting some market separation between the Viper and the Capricorn.
