You might consider placing your motors lower on the body.
The drive motors should be on the horizontal plane of your cross sectional center
of pressure (CP) and aligned with respect to the center of gravity/buoyancy so
that your sub does not pitch while under power. The motors on the top of
the sub should be lower so that they are in the water on the surface and thus
effective for making turns.
Don’t have the book handy to pull out as reference, but
your VBTs are probably excessive in size. While Ray’s comments
concerning free surface effects of a partially flooded VBT are correct, baffle plates
will not help much with an excessive angle with long, thin VBTs. You will
be either pitched up or down and having venting issues.
