      In report of resistance calculation I found out, that Freude number (Fn) for the same speed is different in Delf series (98) calculation and KAPER calculation. Can somebody explain me, why?

      Delft series uses 70% of the Lwl for determining the Reynolds number. Apparently this 70% is also applied to the calculation of Froude number.
