I attach mine to the front D ring with about 6 to 8 feet of rope. We simply put it in the water in front of the raft and since the wind is blowing us upstream when we deploy it, the sock drifts downstream away from the raft. Once the rope between the raft and sock begins to tighten, the sock billows open and fills with water. We regulate the amount of rope we have out depending upon the conditions at the time, but it is usually about 6 feet. As I mentioned earlier, we have 1 person manning the rope and drift sock, ready to pull the dump line on the sock if need be. I was pleasantly surprised at how hard the current pulls on the sock and how well it often works. Does not work under every circumstance, but I don't venture out without it tucked away in the boat someplace. A good buddy put me on to this idea. He has a large DRE cataraft and ties one to the bow of each cat tube. Works good for him.
