Minor Update:
A couple nights ago I finally managed to do a Hog Islander, something I'd wanted to accomplish but I'd just never gotten quite right. It will be assigned to both US and UK shippers in the initial release (later releases (hopefully) will add versions for the USSR, Panama and maybe Brazil).
By now, almost all of the major US dry cargo companies are represented. American Export Lines, Alcoa, and so on.
It's late & I'm too tired to post anymore.
