There was an effort a few years back (I looked it up, and it was 2001, oops) to market this, a perpetual cruise ship for retired people. "MS The World". I suspect it didn't do all that great, since there weren't a lot of copycats, but it took until covid to strand the project. Now apparently there's a second ship trying the same business model, "Villa Vie Odyssey". Predictably, the marketing suggests it's the first one ever of its kind.
