Hi, I’m gonna be starting the course to become a mariner (deck officer) this September and while I was looking up various stuffs about ships on youtube I noticed that on most vessels the captain orders the helmsman to steer the ship.
Why is there a need for this? Can’t the captain just control the vessel like how aviators do? Is it because the ship is too big and the captain constantly has to move around the bridge (when the ship’s inside the harbor)?
Edit: Another question: Why do we need the engineer? Do ships not have an automated engine control system like they do on airplanes, trucks, etc?
