I want to talk a little bit about quick response. Back in the day, when they set sail on boats like this, or probably much bigger and that, crossing the ocean, they sailed for a day, they could aim for the stars. If there was a night where they could see the stars, they could then change the directions and so. So they could go a lot of that sideways type of sailing, before they could respond to a problem with the tools they had. Nowadays they have GPS, or satellite tracking or something like that, so they will go more straight on. Take that thinking back to an operational system, in a workplace somewhere. If you would try to correct to your deviations….check the video for more.
