I wouldn't tie the fenders to the life lines to begin with. If you don't have any other options, tie them to the bottom of the stanchions. On my dock, I've eliminated hanging them off the boat altogether by mounting them horizontally on the dock. I don't have to put them away on the way out, or take them out and hang them on the way in. They can't ride up on the dock, thereby becoming worthless. 100% of the fender contacts the hull and therefore cushions the boat. Vertically, it's 25% max. I find old fenders floating or laying around and use them, and keep the nice ones below. The only downside is that I'm out of the habit of getting fenders out when approaching a guest dock. I can live with that!
