Hopefully you are feeling a sideways motion. They are used three or four minutes on a good day, ten if things are going badly. An onshore or offshore wind can really screw up handling alongside, especially with the sail area on today's cattle boats.
There is nothing magic about the thrusters. It's just a pipe through the ship with a propeller in the middle. You can put them on your 35 footer these days.
I still think shouting orders to be passed in another language to an array of tugs is far more romantic than flipping a toggle switch, even though the ship does seem to go where you want with the toggle switch.
