where does the captain sit on a ship
Bridge (nautical) The bridge of a ship is the room or platform from which the ship can be commanded. When a ship is underway the bridge is manned by an OOW (officer of the watch) aided usually by an AB (able seaman) acting as lookout. During critical maneuvers the captain will be on the bridge supported, perhaps, by an OOW as an extra set of hands, an AB on the wheel and sometimes a pilot if required.
William McMaster Murdoch Murdoch was the officer in charge at the bridge when at approximately 11.40pm on 14 April 1912 a large iceberg directly in the Titanic's path was sighted. Quartermaster Robert Hichens, who was at the helm, and Fourth Officer Joseph Boxhall, who may or may not have been on the bridge during the collision,[2] both stated that Murdoch gave the order "Hard-a-starboard",[3][4][5] a tiller command which would turn the ship to port (left) by moving the tiller to starboard (right).
