Re: principal on stability calculation in delftship

That’s correct. The “Include shift of COG” setting indicates that the actual cog for liquids is used in the calculations which is the most accurate setting. In fact it reflects exactly what happens with the fluids in practice. By disabling the setting you downgrade to the conventional method which only approximates what happens. The calculated righting levers can be either too high or too low depending on the tank configuration that you are using.
