Here is what I have, the Deck Mate 25 by power winch. Very good unit but a little pricy.

Is a free fall so you would want to let it out a little before you were at your anchor spot. And you have to wind it in just a little to reengage the gears. Lost a anchor and rope year before last. Rope wasn't properly attached to drum and didn't get it engaged. Was dragging to slow drift. It unrolled and went byby.
