Panorama pic of where
USS Harry S. Truman is supposed to be anchored. The sailing ship to the left is 70 m long (water line) 500 meters away and the cruise ship to the right is probably about 200 m long.
But it would be cool in Mutant. A bit like the Statue of Liberty in Planet of the Apes, or the crashed Star Destroyers in the recent Star Wars movies. But in a game that's supposed to be based in reality? Not so cool.
