Glad you are continuing to learn something from me. As we all know, a stiff boat follows the waves due to its significant hull moment, creating poor movement. Perhaps you need to review and learn from my previous posts. But to quote a book written 150 years ago:

A manual of Naval Architechture, 1877

"A stiff ship is... A steady ship on the contrary when exposed to the action of waves keeps nearly upright. the stiffest ships are the least steady."

Paulo.. I have pointed this out before. The characteristics of a rough water boat is it reamains vertical in the presence of waves. This is the characteristic of the IP.
