Two things stick out to me. One, that is an awful clean deer to start with, with no bloody hole in the rib cage, leaking blood. Two, we got no picture of the carcass to see how much hair was sticking to it from the tarp. miles
The processor I use does it similar except it's done while hanging. They have a winch that lifts the deer, and another winch that has a cable through a block anchored to the ground under the deer. Very quick way to do it.
Heard a story once of a redneck that tried this while a deer was hanging in an old barn. He pulled the whole barn down
I've skinned deer that way when I hunted Kodiak Island on a commercial fishing boat. We used the boom to lift the deer and tied the hide to the rail. It worked very well but you had to make a few cuts, in a few places, to prevent the flesh from tearing away.
I've done it that way too, though used a rock instead of a golf ball. Tied deer to trunk of a good sized oak because the hide is on pretty tight. It works way better if the deer is warm. I also have done it before gutting.
I did my first one that way in about 1972. I have done it a few times since over the years when we were in a hurry. My younger daughter does all of hers that way. She likes the method, and she has an electric winch and I-beam frame on her carport that is hell for stout.
I got a nice Muley in 1980. We used this method (kinda) with a tree, a rock and an electric winch. Worked fine but skinning a Deer isn't a big deal to me and I don't remember using this method again.
