The Forone has not stepped hull.
I have been to some of the races and it amazing to se how they can do so well when being the slowest boat and having the shortest hull in the class.
Flat water is not what they want but they perform really well in the ruff seas.
They have tappered tubes and also built the tubes futher into the boat for having less resistance to wind.
Boat makes 67knots with 2 X 250 XS optimax on flat water.
