Of side note: I haven't watched the show but the Deadliest Catch boat is often moored right next to an on-the-docks Seattle fish restaurant I frequent. After fish and chips, we usually mill around the docks looking at the fishing boats and yachts and I've walked by the Deadliest Catch boat numerous times. And, if you want, you can buy fish directly from fishing boats there.
