What scientific reason would explain why I have to cock my head 4 different ways to read each of my 4 Raymarine instruments, or is this just simply a lack of quality control on the part of Raymarine? I get the same results with two different brands of expensive polarized sunglasses.

I can't even begin to give you a scientific reason for the phenomenon, but suggest it's just the way it is with polarized lenses - nothing to do with the instrument maker nor the lens maker.
I think you'll find the same thing happening in your car, if you have some LCD digital readouts.
I think you'll also find the glasses change the appearance of things like windshields and car door windows.
I like what the lenses do to enhance the blue sky and define clouds, but I definitely cannot see hazard markers on the water as well. We sail on a shoal lake and have numerous can and spar buoys marking thin water. The cans are hard enough to see and the spars are almost impossible.
As I mentioned in an earlier post to this thread, I would not buy polarized sunglasses again.
