#2 Actually, Sig's a pretty nice guy (he was a couple years behind me in Shorewood High School, just North of Seattle). Notice a lot of the boats they feature are based out of Seattle. Long-time fishing industry around here, especially strong in Norwegian community.
I haven't been on any of the boats in the show, but I've been on a couple like them (just visiting, not working in AK). It's really amazing how large those boats look when docked in calm waters in Seattle, and how tiny they look when getting battered in bad AK weather and filling up with crab.
