The CO keeps station generally on the bridge. When not on the
bridge,
the CO would usually be in his sea cabin nearby. By my recollection,
on every USN ship I have been on either as a midshipman or during four
years of active duty (two as ship's navigator) this was the case.
Also, navigation work was generally performed on the bridge where
there was a chart table, communications with bearing takers at
peloruses, etc. CIC might function as a backup, however I never saw a
CIC really equipped for navigation: a chart table with a chart on it,
etc. Ships I was on also had a chart room near the bridge for use by
the navigator and quartermasters. Equipment like the chronometers,
Loran set, fathometer, publications, etc., would be kept in the chart
room as would charts not actually in use. Sight reductions would
generally be done in the chart room.

Not sure what the current US Navy practice is,
but during my time aboard ship (USS Nashville, mid-70s) all of the people in my
area (OE Division - Electronics Techs) were also qualified as CIC watchstanders.
Besides maintaining various other watches
(surface and air radar, maneuvering board, electronic intelligence-gathering,
etc.), we also functioned as what I'd call a "hot backup" to the bridge
navigation. I remember the bridge
frequently consulting with CIC about a navigation issue, and hearing "CIC
concurs" on the squawk box. One of the CIC
watchstanders was assigned to keeping a current plot on a paper chart, and we
also had a functioning DRT (Dead-Reckoning Table) that was fired up on occasion
(I think mostly for the benefit of those who hadn't ever used one
before).
