I'm planning on moving onto a liveaboard boat next year and was really excited about Starlink until the price was revealed to be way out of reach for yachtsmen who aren't in the super-rich bracket. People assume boat owners have lots of money but the very fact of owning a boat means they often don't!
I've been tempted to try RV Starlink as an alternative but I don't think having my livelihood reliant on 'Elon Musk might think I'm taking the piss and cut off my internet' is a great idea. Realistically 4G and 5G coverage is good enough where I'm intending to go that it's not a huge issue.
