The Chart House was the Navigator’s primary workplace, where the Navigator and Quartermasters stood at the chart table to plot the ship’s location and future track after making observations of celestial bodies such as the sun and stars, using computations and tools such as the parallel motion protractor to plot lines of bearing. The ship’s current position and future track were also maintained on a chart in the Pilot House, or Bridge, and the Navigator tracked course changes during maneuvers with the task force so the battleship could maintain its station in relation to other ships in formation. Four methods were used to determine position in navigation: piloting, dead reckoning, celestial navigation, and LORAN, an early electronic system that received and compared radio signals sent on the same frequency and time from two shore stations. LORAN was installed in 1944 while the battleship was stateside, and Chief Quartermaster Joe Ringhoffer was trained to use it, but he said it was never useful in the Pacific because the stations were so far apart, while the Assistant Navigator found it very inaccurate and useless and preferred the sextant and older methods. Crew memories from the Chart House also recall Don Greene, a Seaman 1/c, learning to type there while assisting the Navigator’s yeoman by typing logs from the Officer of the Deck for officers to sign as the ship’s official deck log, and Navigator Commander Kemp Tilley rigging a leather couch with wire, a spark coil, and a hidden switch to shock smokers and drive them out of the sealed space.
