In that other post (Lil Bigfoot
I mentioned the drama of trying to get that triangular shade cloth tied taut in all three directions.
Before he left for the lake, super smart hubby achieved one great tie off by draping rope over the top of his van, and then simply securing in the rope cleat on the boat (which was on the other side).
The cleats look like this, and, and you can pull your rope tight and the cleat holds it tight. No knot tying... totally cool!
Thinking about this later I am totally tempted to install two marine type cleats on the streetside of Lil Bigfoot
just for this kind of use. But probably with a different shape of shade cloth.
