So, in that picture, are the two guys driving the boat like an airplane (pilot and co-pilot) or is one handling the boat heading and the other handling the depth control?
Do both wheels work independently or in unison like on a plane?

The Ohio class boats have two steering wheels operated by two sailors. One of the steering wheels controls the hydroplanes on the stern and the other steering wheel controls the stern rudder and the horizontal fins at the sail.
The sailors can steer the boat by using the stern rudder to turn starboard or port and the hydroplanes to control the fore-aft angle of the submarine.
