You know you’ve always wanted to ride in a tugboat as it pushes around a huge cargo ship, right? Well, that’s what we do in Episode 3.

Meet a tugboat dispatcher, a skipper, and the first female captain of an American freighter. It’s a case study in how globalization works and our first look at the challenges the port faces.
