There are several narrowboaters who record their travels on YT, perhaps the best, certainly one of the first, is "Travels by Narrowboat", with 6 seasons on Prime[1] and the more recent years on YT[2].
Kevins videos have always been great, and from the same generation of “BoatTubers” as myself and my wife and dog (we’re Minimal List), but there were earlier (including the slightly more venerable CruisingTheCut) and a whole slew of great channels that came later, all speaking to different tastes and styles and audiences. My personal favorite as an introduction to narrowboat life has been Robbie Cummings for a while now; he ended up on the BBC as Canal Boat Diaries, so the production quality is just great, and he’s also about the nicest and most affable fellow I’ve met on the canals, which in this community is saying quite a bit.
How interesting that you're on HN. We regularly travel up and down the ship canal to/from Manchester. Give me a shout if you're ever in Manchester again, I think we'd enjoy a beer.
