how can i use cheel 0~60 data to get the result in green line

[yuyewuyuconan]

when cheel the ship's vcb>vcb0 ,so vcb in this table is distance from B to ro 10deg base line ？

Calculation of righting lever:

For cross-curves based on KG=0, called KN curves:

GZ (righting lever)= KN - KG*sin(heel)

where in this case:
KN = PN
KG = KMT

The draught is calculated based on the load case. Based on the load case a certain trim and displacement can be calculated using the hydrostatic tables. Based on this data the appropriate cross curves are selected for calculation of the stability curve.



google cross curves or kn curves for more information.

thank you !IT is not easy to make a stability software.

well that's why others do it....
