A while back I stumbled upon a youtube channel[1] dedicated to just solo sailing trips. I'm not sure how much is him/his video composition vs. just the subject matter of filming one's seemingly minuscule progress across the vast reaches of ocean, but I became entranced by just the calm plodding-ness of his days. Did a great job of breaking down trips and prep in some of his videos.

Can't speak to his latest stuff, so YMMV, but for a while it worked for me as incredible background. I imagine there's more and more content like this on YT, what with more powerful technology becoming more ubiquitous.
