I like sailing channels are there are several I watch at least semi-regularly.
SV Delos - Has gone from a party on the sea to a family sailing over the years. Has sailed every ocean and visited many many countries. They like to interact with locals to give a nice feel of where they are. The ultimate show of a cruising lifestyle. They also dive in some amazing spots including with sharks.
La Vagabonde - Riley and Elena from Australia. Like Delos, they have added a child and just recently a 2nd. Don't follow as closely as I used to, but their production is good. Riley does a lot of free diving and spear fishing. Less interaction with the locals, but beautiful locales. Recently have spent a lot of time in the Bahamas.
Sailing Doodles - Entertainment with lots of bikinis on women crew. Bobby is the constant and he beings on different crew from time to time. Always visiting in sunny places and changes boats on occasion. Currently in the Mediterranean.
MJ Sailing - Young couple from Michigan who sold everything and bought a boat (now in their 30s?). Not as exciting a couple or as good of a production (but not bad). They're very relatable. They sold their last boat and are currently doing custom building a catamaran. Lots of boat building footage the last 6 months or so.
There are many others out there.
There are many others... Some are more sailing oriented. Others focused on the boat, maintenance, fixing stuff, etc. Most are focused on sunny places like the Caribbean, but others in Europe/Med, near England/Scotland, etc.
Also watch various wrestling channels, college football and a lot of misc. crap.
Oh, and lately, been watching a few vids on scammers, namely tech people trying to catch them.
Mark Rober is interesting. Former NASA employee who can build cool gadgets. Only does 1 video a month, but they are entertaining and creative. Leading a group to stop/bust scammers, porch pirates, etc.
Jim Browning, Trilogy Media and Scammer Payback are others working against scammers and call centers in India. The combination of Rober, Browning and Trilogy just got a whole call center in India shut down last week, with at least 15 people arrested.
