Never heard of it.
There is actually a CD available titled ‘Yacht Rock’, I own it.
There is a user on Spotify who has a personal playlist called “Yacht Rock” with some of the same songs that you listed. That’s the first that I’ve ever heard the term “Yacht Rock” used.
We don’t get that kind of polished popcraft today, crafted by studio musicians, mixed and remixed, infused with saxophones and other “smooth” sounding instruments.
We don’t get that kind of music today because none of the current bunch are musicians. They are pin up models whose voice is run through a computer 30 times. Same computer makes the music because none of them play an instrument.
When this “yacht music” (which I don’t agree with, sounds like it came from someone not alive when this music was made) musicians were signed for making music, not being pretty. Examples; Boz Scaggs, Donald Fagen (Steely Dan), David Gates (Bread), David Pack (Ambrosia), all outstanding musicians but ugly as homemade sin.
Even Elton. He’s nothing to look at as a guy or girl, but he and Bernie Taupin are absolute musical geniuses.
We own a ‘yacht’ and have been boaters for many many years. Have never heard of yacht rock........and any man dressed like that would have been laughed off the dock of anywhere we’ve ever been. Lol
Closest to that I’ve ever seen is on a Green Turtle Cay in the Bahamas that has a hotel where every one docks. It is British and you have to ‘dress’ for dinner. By dress they mean a shirt with a collar and no shorts. Lol
I really don’t think Rocky Burnette belongs on that list.
“Moonlight Feels Right” by Starbuck (1976), which is about sailing the Chesapeake Bay, would fit into this genre.
