Hi,
i'm the French AHPC dealer, and could say that weight of the Viper is around 130 kg.
You could look on AHPC website or my one, weight is write at 129 kg.

It is certains, if it'll be possible to made the same boat but only 107 kg, it'll be faster. A lot ? I think not, but it'll be faster.

Only for build a Viper as stiff than now but with a weight of 107 kg, it must be full carbon, and it cost perraps 25 000 €.

My view is are we agree for F16 will be expensive boats or not ?

If yes, all is agree, if not without change we take a risk.
