Set the desired trim with the TRIM command. (You could use the DRAFT command instead)

Set the desired heel with the HEEL command.

Then the HS command (not GHS) will give you hydrostatics at the trim and heel you have set. HS ignores the VCG and lets you roll the boat around anyway you like.

Check the help file for both commands. Pretty good explanation of the difference there.

In reference to tanks: Basically,

The surface of the liquid in a frozen tank does not move as the vessel trims or heels (as if it were frozen).

A spilling tank is similar to a normal tank until the surface of the liquid passes a predefined reference point. At that point the contents "spill" from the tank and the load is decreased. Unlike the real world, tanks 'unspill' if the angle is decreased.

Check help file under TYPE (I believe).
