I wonder if "sucking" wash at an angle may reduce the effect of the rudder.
I don't believe the angle affects the walk by itself.... only influences the
wash over the rudder.

Don't the newer cruise ships now use pod screws for better control and

I concur.

Well since none of us are experts in the field it only makes for a venue to
compare alternate viewpoints. It's of interest only to those of us who
consider the problem and wish to explore the situation.
