Boat enthusiast here, I'm afraid even that'll be a struggle! I'm planning to move onto a sailing yacht fairly soon and carry on my job as a backend web developer, mobile internet is good enough to make this viable and things like Starlink will make it even easier in the coming years.
I suppose you can still turn off the telescreen if you want to though, if you sail out of range of mobile towers and turn everything off you can hide from the world pretty effectively.
