Kev, in Australia the Skipper seat is pretty easy to get a hold of - any chandlery would be able to access them, and they're not overly expensive. I imagine they'd be easy to find in the states.
I have since come up with a more secure way to mount it in position. I haven't changed the turnbuckle system at the back of it (that works great) but I have changed the fast-release buckle system for a cord & cleat system, which holds the seat in position better. I'll update this post with some photos of that when I get a chance.
Glad y'all enjoyed the video. The next one will go into more detail on kit - safety, nav, 1st aid, rods, reels and my favourite lures (and why). That and of course whatever worthy fishing action I shoot in between now and then
