Jazz Rock, yes. But there’s something insipid about the label Yacht Rock.
There is something "cool jazzy" or "smooth jazzy" about some of it, and there's some overlap with Kenny G. type music, but doesn't "Jazz Rock" refer more to music like Herbie Hancock's or Chick Corea's? I think of something a little livelier and funkier. I also think, probably wrongly, of Chicago and its brass section.
Yacht rock is kind of a stupid label, and it has cultural associations that would be considered problematic nowadays, but it was probably considered less insulting than "Easy Listening" or "Middle of the Road."
