There is a wrong explanation of the bank effect at 1:18. The bow sheers away from the closer shore not because of being pushed by bow pressure zone as explained in the video, but due to suction force acting somewhere abaft the amidships which is equivalent to a force acting aft of COG which also creates turning moment, deflecting the ships head away from the bank. This is called bank effect.

You need all these forces to successfully pass and meet in narrow channels.
