Yes, it will. For that reason there are
lifting lugs on the underside as well as on top. But in addition to rolling
over, as the drop weight is under the bow it will raise the bow above water
allowing an emergency exit. OK, a dicey one as the sub will probably flood in
seconds.

Sub "SOLO" Stability
Interesting design, so I have a
question. If you were to drop the emergency weight (like in an
emergency), wouldn't the sub become unbalanced (top heavy) and roll over?

Shawn,
Because Solo is intended as a "flying" sub, it's designed to have a
very small self-righting moment. One of the heavier weights is an
emergency drop-weight under the bow. To counteract the "lowness" of
the drop weight, internal items are mounted as high as possible inside the
cabin. So the batteries, for example, are "suspended" from the cabin
ceiling rather than sitting on the floor. This is exactly the opposite of what
you would shoot for in a conventional design, which is to carry the batteries
as low as possible in order to make the boat more stable. If Solo had
conventional stability, she could never roll or fly inverted.
Given the batteries are snug against the hull "ceiling", I can't
reach the lugs to connect the cables unless they are upside down. Plus, I don't
want the lugs shorting out against the hull. If they cannot go upside
down, I'll probably have to lower everything by about 3". Plus, all the
cables will now be a few inches too short.
