Dear Mary,

I had done MANY VPP works for great multihulls and intensive tank tests, so I'm right on paper, but also over tank tests datas... the ONLY WAY to go faster than 22 kt on small catamarans is to plane at a certain speed...the frictional resistance increases at the square of speed, so at ( 27 ) x ( 27 ) = 729, you have 1,8 eight times the resistance at 20 kt = 400 !!!! and your power stops to raise as soon as you reach the maximum heeling moment, already gets at 20 kt...

I am quite skeptic...

Frenchie
