As a kid in the late 70’s to early 80’s we used to buy some old land yachts. We’d yank the engines, re-cam them, replace the rings, in essence give them some serious performance boosts.
But the cars were always what we referred to as boats. They looked like boats, they handled like boats, you get the general idea. Most of what we played with was 60’s and early 70’s vintage. But I found these shots of a true land yacht.
