Using KN Curves to construct a GZ curve - Advanced ship stability for mariners

This video uses a numerical example to explain the procedure of constructing a GZ curve using data from KN curves. Why KN curves are used and their distinct advantage over the cross curves of stability is also explained.

This is video 28 in the series of videos on ship stability.
