Starlink is indeed an interesting technical solution to the problem of connecting sailors to their families. I've only been on short cruises, and I found those to be incredibly isolating. The experience was completely unlike camping, for example. At least there, you're under your own power, and returning to civilization is a matter of walking back in the direction from which you came. At sea, on a big ship, you are stuck in the middle of nowhere, powerless to go anywhere, an empty expanse of fathomless water in every direction. I found the experience simultaneously intense and depressing, and I can't imagine how sailors manage it even in the digital age.

It has also been suggested that at strategic locations you could have swimming ground stations in order to cover a pretty large area.
Eventually however it will cover everything as the satellites will communicate directly between each other with lasers.
