      This extra flotation is down low, exactly where you don't want it.

      In the Long Micro, the 532 pounds of 'down low' lead ballast is
      'negated' by 150 lbs of 'down low' air buoyancy, and made less
      effective.

      The flooded keel can be seen as being as water ballast in the Micro designs.
