vary the geometric configurations of the sidewall amidships, in order to evaluate the
effect of the geometric configuration of sidewalls on transverse stability.
The effect of the lines of a bow sidewall is smaller than that of midship lines. If we
assume that the lines of the bow sidewall will be fixed and the line of hard chine is
above the loaded water line, then the main parameters of the sidewall can be defined
as follows:
