So if the story that it was on autopilot is true, that is a major no-no.
I can not imagine a case where auto-pilot would be 'on' when approaching a pier ..... however I'd be careful about semantics ....
what I'd call 'autopilot' was traditionally a device that when set to a particular compass course, kept the ship steering that course ... it steered but was not 'smart' wrt navigation; the course was adjusted when navigation revealed a drift from desired course due to wind current etc. Today's bridge has an integrated system where the 'autopilot' is talked to by a computer with GPS inputs and a set of 'way points' programmed by the navigator and this system detects where the ship is and can adjust the autopilot and often speed to ensure the ship is on track and on time. These are normally used for open water sailing. Once a ship gets into 'pilot waters' it is my experience that hand steering will be used ESPECIALLY during docking/mooring.
but wait, there's more:
old designs had a helm controlling the rudder, throttle(s) controlling the engines and similar throttles controlling bow/stern side thrusters and all of this was controlled manually. TODAY all of this is often tied together by a computer and the 'conn' turns a dial to tell the computer which way the bow should point, and a joystick is used to command the direction of motion and a computer controls all the parts to make this happen. Not what I'd call 'autopilot' in a traditional sense but probably MORE in terms of what it does. This system would almost certainly be 'in use'. Can things go wrong? ABSOLUTELY ......
