Question:

I am running several damaged conditions but I am confused about the
displacement in the Status command.  Why is there a displacement much greater
than the total weight initially set?  There are no loaded tanks.


Answer:

The STATUS report shows weight in the first section and displacement in the
second section.  If the vessel is in equilibrium, the two totals are the same
(or very close).  In case of damage you will see the flooded tanks deducting
from the overall displacement of the hull.  You have to compare total weight
with total displacement.  With flooding you loose displacement in certain
spaces of your hull.  The STATUS report shows first the displacement of the
intact hull envelope, then the deductions for the lost buoyancy in the flooded
spaces.  If this would be confusing to the reader, you could "turn off" this
detail by means of the TOTAL subparameter:

  STATUS WEIGHT, DISPL:TOTAL

which would show only the total displacement.  (Of course our total is less
than the HULL displacement because we are adding negatives to it.)
