GZ and Righting Moment Spreadsheet?

GZ and Righting Moment Spreadsheet

Edit:
.xls file attached on the next thread.
Copy "Cross Curves of Stability" data, obtained from Archimedes MB or (maybe?) Freeship+ and Paste into this .xls
Output: GZ arm curve and Righting Moment curve of your hull, for big heel angles.
You can do small changes to VCG (also called KG) to match the stability curve you want for your vessel. (For big changes, you should modify original hull, displacements and VCG...)

 

Attached another one with 3D graphics to show 3D stability mesh. New stability image.

You might look at this thread I started way back. It references Freeship, but the info might be useful.

Thanks LP. So my thougts about KN in Archimedes were right. All this confusing thing about K, N, H, M etc. could be much more clear with a simple graphic beside formulas, just as you did at your post.

 

This is my own image...

 

here's another one, may be better to understand Archimedes KN value
