I really don't want to have a polemic discussion, or a comparaison of this one is better, this one is heavyer ...there's no interest for that. Like i'm professional, after I take volontary exemple on AHPC boats i sell, for nobody outside could be feel ofensed.
there's some facts :
A Taipan haven't be devellop for Spi. Add a spi and few years of experiences on cat design : the shape, volume and stifness of hulls and platform need to be increase. Viper was developed on these bases. Like they haven't the same specifications at the begining, a Taipan and a Viper couldn't made the same weight with similar build, at the end it's evident. So for made a Viper at the weight of Taipan, Viper should be really more expensive than Taipan with an more high tech build. That's all, there's no polemic around that.
The 2 boats are agree with F16 rules, and sail together in F16
The 2 boats like "production boat" haven't the same rating because their data are differents. A rating is calculate only on data, there's no adjustement if it's an old or new design, a bad or a very good design ... so calculator said Viper is slower than Taipan.
All that for me is correct, and need no change.
In A class, build a 75 kg boat with glass hull is possible, no problem, i had an AJ under 75 kg. Why racer buy all carbon hulls ?
In F18 180 kg is a confortable weight. It was easy in the past to have boat at 180 kg or a little under. with new design ...some of them have difficulties for stay at 180 kg, at world boat with weight corrector isn't a lot. Why ?
After for give some numbers ...
(sorry if power ratio isn't the good term in English but i think you'll understand)
power ratio of an A class is 340 kg/m F16 1-up (103 kg) 395 kg/m Viper 1-up 415 kg/m F16 2-up (107 kg) 630 kg/m Viper 2-up (130 kg) 650 kg/m F18 750 kg/m Tornado 800 kg/m
Take an A class like references
for made an F16-1 up power ration increase of 16 % and weight of 37% for a 103 kg boat.
for made an F16 - 2up you increase power ratio of more of 80 % but you increase weight of only 43 % for a 107 kg boat. (73% for a 130 kg boat).
Now take an F18 like references
for made an F16 - 2up you decrease power ratio of only 16 % but you decrease weight of 41 % for a 107 kg boat, (28 % for a 130 kg boat).
for made an F16-1 up power ration decrease of 45 % and weight of 43% for a 103 kg boat.
volontary i don't want give my conclusion about ..
My view is only a 25 or 30 K€ boat full carbon, and full victory should accept with smile by the class ?
