There is no genre called "yacht funk," but maybe there should be. It's like a corollary to the widely recognized "yacht rock" subgenre, with breezy, loping time signatures, a languorous disco pace, and maybe a little flicker of guitar, George Benson style. This genre we propose is heavy on jazz funk, true, though it wouldn't be complete without someone doing his best Michael McDonald impression, like George Duke on "Every Little Step I Take," or the Gap Band on "Yearning for Your Love." (We will have to save the "Late 1970s soul singers who wanted to be in The Doobie Brothers" phenomenon for another post.) There are even songs specific to summer sun and sailing, like Benson's "Breezin'," Earth, Wind & Fire's "Sailaway," Kool & the Gang's "Summer Madness" and Donald Byrd's "Wind Parade."
The joke, of course, is that yacht funk is profoundly un-funky. But that's part of its charm. After all, what's funkier than trying to relax on a boat in the middle of the ocean?
