Wind causes a straight ratchet strap to vibrate, almost like a reed in certain types of wind instruments. You’ll notice the same thing if you strap something to the roof of your car or in the bed of a pickup and drive it in the highway. It makes for a very noisy ride.
Giving the strap a twist or two, wherever it’s not contacting something, will stop it from vibrating and it will be much quieter.
How does that work if you could explain?
