Progressive Yacht Rock?

Fair enough. But I'm going to keep it loose in classifying the "prog world." And I'm going to go ahead and answer my own question anyway at the risk of being ignored. I can still keep myself entertained.

I say Supertramp is the prog equivalent to yacht rock, particularly with albums like Crisis?... through Famous Last Words. The production is sleak, there's an art rock focus on arrangements, and there's an element of jazziness, but it's very accessible music and occasionally somewhat cheesy (which isn't a bad thing, doesn't always have to be). To be clear, Supertramp is NOT Yacht Rock. But I think Supertramp is to prog as Christopher Cross is to mainstream/classic rock.
