No there were a handful of PC releases, a couple mobile, and a browser game release too, if I remember right.
I just saw there was a 2019 released mobile game Daikoukai Jidai VI (Uncharted Waters 6) but almost all of the games were Japanese, Chinese, and/or Korean language releases only.
I think this is it: https://play.google.com/store/apps/details?id=com.joycity.oceansandempires
I'd love to find a more modern version of that kind of game, too. In the meantime you could emulate the original. It works just fine with snes9x. In the meantime, there's Oceans & Empires which I haven't played yet but it looks interesting and has decent reviews.
Edit: After some more searching, I found this, which looks decent, but has a steep price tag. There's a demo to try, limited to sailing around. I quite like the controls, but as one of the reviewers mentioned, the UI needs work, buttons too small, etc.
