It is not often that this blog is used to show bad practice, however in this case some pictures tell a whole story. Ship is compliant by design for rigging a combination. How about the operator(s)?

This movie shows how to create the Characteristic Diagram for Wind effect on ships and limits of steerability under strong wind. It uses the previous demos made with the SAMMON Planning Software on turning tendency of ships on straight track and in turning motion.
