OK - but I wonder if these issues are necessary limitations?  In other words, why couldn't more
effective pontoons be used just fin instead?  And the proportions varied somewhat?

Sure, from a surface-vessel point of view, it would be less than optimal because of all the
displacement in the wings, vs in the central hull, but that's a compromise - not a showstopper,
yeah?

No... I didn't realize that at all.  Please explain.  If a "regular" sub could "sail" underwater,
that would be a fascinating technique and quite the fuel-saver.
