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.
