Anyway, duct tape... take ~3 feet of duct tape. It's a two-lane road. Trust me... mentally, draw a lane line down the middle of it, sticky side up.
In one lane of your duct tape road, lay the first three feet of winch rope (drum end), on the sticky side.
Stick the tip of the rope against the drum flange, tape towards the other flange, on the drum.
Overwind the tape and rope, so that you have tape on the drum, and rope on the tape, for the first three feet, as you flatwrap it onto the drum.
Enjoy that your rope will now only ever come off the drum again when you want it to.
