+Fishing boats and oil derricks let you exploit sea resources.
+Navigating them back and forth between harbor and fishery / offshore
+oil field is rather tedious.  Autonavigation lets you automate this.
+.s1
+It is more commonly used for fishing boats than for oil derricks,
+because oil fields are commonly configured to deplete quickly, and are
+often too far from harbors for the slow oil derricks to make
+autonavigation effective.
+.s1
+This is an example of how to set up a fleet of fishing boats
+so they will take their food produced each update and drop it off
+at the harbor of your choice.  Oil derricks work exactly the same.
