good point. but when it comes to slow reaction times, if the guide is giving the wrong order, by the time the captain can counteract that it may be to late. but you are right. we'll just have to wait until we know more about what really happened
Not sure if reaction time plays any role when talking about ship this size. It takes time for it to respond for any command, e.g. course change.
But by your logic, couldn't one argue that reaction time plays a rather large role? If you are navigating a narrow canal with thin margins for error, wouldn't you need good timing to start a manuever at a certain point so that the ship is able to respond by the time that you need to truly adjust it's position? If some sort of weather event/anomaly caused an unexpected change of course, wouldn't reaction time be even more critical because you have less time to make a correction if you don't act immediately?
