And what we learn from it ?

High values ​​at station 1 (Truss 1) and Station 2 lead to a flat spot in Heckbeeich.
This is favorable, to move to the Finn in the sliding mode, leads to a horizontal swimming position and to a greater wetted surface.
In displacement mode, the speed of the Finns on
as. 4.5 km / h limit multiplied by the square root of the waterline length.

Smaller values ​​at station 4 and 6 could lead to a narrower waterline and thus lead to more speed. In addition, a sharper bow leads to better behavior in a seaway.
