Choosing to build a high volume hull was a design and marketing decision on Greg’s part. One might say the Viper is, in essence, a length compressed (rather than globally scaled down), modified F18 Capricorn, or a for lack of a better description, a stubby F18. His design path proves to be fast in capable hands (as is the Blade & Falcon). To me this is not a drawback, but one of the beauties of the box rule...it lets Greg or anyone else for that matter, explore the design limits of the F16 within the box rules even if they do not take advantage of maximizing the platform in all areas.
Choosing to make the boat well above the minimum weight and asking for the rules to change is little different than someone making an F16 16.8% longer than the box rule (which is arrived at by dividing 125kg Viper weight by the 107Kg minimum box rule weight, which would translate to 5m X 1.168 or 5.84m /19’-2” length boat) and wanting the rule on length to be increased to accommodate one builder. This, despite the fact that the rest of the boat building community has designed and built F16's to the stated 5m rule. I don’t think anyone in their right mind would propose such a change in length, so why is weight any different?
Greg knew the rules before he designed the Viper and consciously designed outside the optimum parameters, obviously he felt the increase in volume would offset the disadvantage of the increased weight. Only Greg knows his production costs and what he needs to charge to make a profit...it may very well cost him more than an "A" cat (although after listening thru the video twice I didn't hear him put a specific dollar amount on it). That does not change the fact that other builders are building F16 catamarans within the rules that are at, or very close to minimum weight at a reasonable price....some 15K (US dollars) less than the proposed $35K price that is being thrown about. Leave the rules alone!
