If it’s anything like airline pilot training, there’s periodic retraining and evaluation to make sure pilots have the right reactions in case of an emergency.

I wonder if they’re required to keep up training to the degree pilots are. It wouldn’t surprise me if they’re not.

I’ve done some sailing but have no real authority when it comes to vessels like these.

Friends of mine are pilots on the Thames (London) and I seem to recall one of them telling me it was over 10 years training before you could bring a big boat in. Pretty fascinating really - they figure out all the tides and weather and plan the route. On the day they board along with a sensor system that sits in the bridge and gives the position to a high level of accuracy.

Lol you're right, controlling a ship with human inputs is so hard that is was the inspiration for a Russian shipmaster to create PID control

But I believe no big ships use any kind of autopilot while near shore. they only use it in the middle of the ocean.

Nope. The military, aerospace, and medical industries have all refused full automation in life-or-death situations with cause.

Isn’t that interesting when compared with ‘machines don’t make mistakes’ wisdom

You'd have to be either a complete headass fresh out of a coding bootcamp or carting around The Agenda That Ate Calcutta to fall for that line of bullshit. Anyone who's spent the wrong parts of their week debugging ought to intuitively grasp that machines are inherently error-prone.

You are not wrong, but nobody gave the memo to the boss of my boss.

Or you just use the tried a true method of recurrent training and simulator work like in aviation

Part of the emergency reponse they are drilled with in simulators are "memory items" that are literally memorized responses to emergencies, i.e. "reverse engines, drop anchor" this is to prevent freezing or indecision. Of course I guess that can still happen but they are trained to the point where it should be automatic.
