Brian,
What's the approximate total weight of the sub projected to be?

It's about 21' long, it goes from about 6' wide ( not including the
wings) in the aft section, and then tapers to the nose to about 2' .
Pressure hull is 30" x 10'

How big is the sub overall?

I have a lot of ballast volume, I think around 150 cu ft. . I was
planning on flooding my ballast tank completely and then be neutral
buoyant, but I think I'm going to be a little bit heavy. I won't
really know until I do some tests. If I am heavy there are some
options I can explore to remedy the situation. In any event if I am
too heavy I could simply not vent any more air out. However,
if I did vent out all my air I may be way too negative an that
could be problematic.
On riding the bubble, I always though that is was very difficult to
maintain a constant depth because you're always fighting your upward or
downward momentum, and with a changing volume of air it was hard to keep
things level.

Lots. Aquarius, for instance, has a small tank forward
of the fwd. MBT which is utilized for trim. No hard tanks or internal
VBTs. Gamma uses a small bubble in the mains, too, also with no VBT. The
Nektons have done lots and lots of dives that way.

Hi All,
Does anyone have experience with trying to control a sub with primarily a
soft ballast tank. I know there is a point where the air becomes
compressed to a point where one starts to lose buoyancy and then
you're headed to the bottom but can it be controlled if you stay slightly
positive and then use your trusters to keep you down?
