DANG ! This is interesting for a number of reasons:
A. You experienced propwalk with a Kort nozzle.
B. You experience it at depth but not at the surface.


A: Which leads me to believe that the force, while limited, is also due
to the precessional force created by a rotating mass, perhaps excited by
pitching forces resulting from hull shape in the case of a submersible.

Possibilities .....
Problem is we would have to wonder if we could fairly compare the two
hull types and environments .... still, interesting.

B: There are far more stronger forces acting on a submersible on the
surface.

G True, you're generally not playing with these in calm waters.
