Maybe he'll believe
you Tony!
Andy, they exist for the people running raceboats at 70/80mph plus, generally set up for racing only, not big heavy rings set up for pleasure doing 60 with the tide behind them! It'll be a great way to loose a couple of grand though, to save you the hassle of getting the gearbox, just give the 2k to me to fund my racing next year!
You could gain 5mph by learning to drive it better. I took my gf's dad out in my last cat, he used to race 3c very successfully over here. In a straight line, in any conditions, he could get at least 7mph more than me every time, usually more if it was rough.
Or is all this about wanting a nice pretty rooster?
