Interesting video on Titanic steering. The engineering was surprisingly sophisticated really, including the hydraulics to the bridge.
These days, many cruise ships rely on thruster pods which push or pull the ship along and and move it in any direction.
Back in the 60s I watched the Cunard Queens sailing from Southampton and several tugs were needed to position the ships to facing down Southampton Water. In 2011 I was aboard Queen Mary 2 in the same Ocean Dock and the ship just moved quietly away from the quay sideways using bow thrusters and pods, backed out into Southampton Water, turned to seawards and was away with not a tug to be seen!
In contrast, the video I just posted of the carrier HMS Queen Elizabeth proceeding to sea from Portsmouth included several tugs as warships are not usually fitted with low speed directionsl means of propulsion. In fact the process was very similar to what I remembered from the 60s in Southampton!
