I'm trying to figure out what the boat will do because it is so different from other boats.
In all other boats I have operated I could count on the the prop walk at low speed before the the speed was sufficient to make the rudder work.

This boat has surprised me on some occasions. Instead of prop-walking to port in reverse as would be expected it has moved starboard.
Sometime port sometimes starboard.

It obviously has a cause it it not magic. I'm thinking that the reason is that the prop-walk effect is overwhelmed by the currents effect on the keel and in one case topside windage.

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.
