This subject popped up in the thread about my updated SLN profile, but this forum seems more appropriate for it so I've copied it here:
There are a ton of narrow boat videos on YouTube, including a few about the history and restoration of England's canal system.
This is a rather nice primer of life on a canal boat. I love his accent and I double love the cookie jar next to his stove. https://www.youtube.com/watch?v=yMKJR5n4gLw
This is one of my favorite series: https://www.youtube.com/c/floatingourboat They're a very natural down-to-earth couple and there's a lot of variety in their video's. To me, watching their videos is like getting a video-letter from an overseas aunt and uncle.
The closest thing to a narrow boat in America is living on a houseboat on a river, but that's a whole different animal for a variety of reasons. Still I do get some tiny-house notions and inspirations from small-houseboat floorplans and videos. And this shanty boat video is interesting. https://www.youtube.com/watch?v=OttgPFvGQYI It gives a bit of history and talks about the riverbanks becoming gentrified and the shanty boat people being displaced by condos, marinas, and touristy riverwalk shopping areas.
Shanty Boat.jpg <<-- This is the shanty boat in the video.
It has an outboard motor and a registration number on the bow which means the powers that be have inspected it and OKed it for use on public waterways, even though it's totally homebuilt.
