Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2020-12-25.

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. It reveals insight on the regions of windward and leeward turning tendency using these diagram as well as for the importance of wind-to-ship speed ratio on the limits of steerability in certain regions of wind encounter angle to the ships course.
