And here, on the right, we have the rather palatial commanding officer's cabin as seen from the passageway that threads its way the length of the boat. The lucky captain has hardwood to sleep on as opposed to a canvas sling. Not sure that would make it more comfortable.
Other features include a miniscule desk, a couple of drawers, and gauges and instruments so the captain can monitor the boat's progress. The cabin is very handy to the control room, so he can be there within seconds in case of an emergency or other development.
