Fascinating. What does the depth indicator say when the sub is surfaced?
Obviously it would not be zero.
That would depend on how far it surfaced. Did it blow all ballast or is
it just barely surfaced?

It can't blow enough ballast to put the keel on the surface. My point is merely
that if the depth is measured between the surface and the keel, (and I have no
reason to doubt that it is) there could never be a "zero" reading.
Think about it - "zero" is the bottom of the boat. If your boat draws
18 inches of water, then your keel is 18 inches below the surface and
thus that is "zero".
Zero is a fictional number anyway and can mean anything.
