I have a small collection of books on ww2 ships an submarines i found this video enlightening i would like opinions on its authenticity i learned a little i never knew. I was looking for the correct area to post this since i thought it should be under boats but i stand corrected

Here'ya go....
First thing I caught.
At point 0:21.... incorrect rotation displayed
From the rear aspect the right one clockwise and the left one left turning counter-clockwise to neutralize the radial spin momentum.
Otherwise, a very informative link. Thanks.
Russian subs..... well, russian subs.... who knows.
I got that slso with both rotating the same way it would be hard to stear

Not really. Triple-screw ships all rotat the same direction. Put two outboard motors on a boat, and they both go the same way.
Now, if you look at a rotating propeller, as very low RPM, the direction the screw is "rolling" in imparted on the vessel.
So, a single-screw RH prop, will want to "walk" the stern to the right (as observed from behind) when going ahead (this being all at the very edge of forward "bite").
A LH screw will "walk" the other way. As will a RH screw turning in Reverse.
When backing, the blades are significantly less efficient, so the effect can be more pronounced.
This becomes a ship-handling skill for getting off--or on--piers & docks.
