You actually contributed another gotcha: a crude oil cargo runs thin
and expands, so the CofG would go up a little higher while the
freeboard goes down, in the Gulf.

You're right: I wasn't factoring in the nature of the cargo. I wonder
if the viscosity of the oil (and its tendency to slosh in tanks) would
also affect stability in this scenario.

I seem to recall the phrase "surface effect" or some such factor
relating to liquid cargo causing ships to capsize unexpectedly, or at
least before it was theoretically anticipated.
