I have had success with this method, although I agree it is difficult to see it in the picture. I think what George is saying is that sometimes the pennant off the mooring ball is pretty long, so as he suggests, I bring the pennant on board and hitch to the cleat on either the port or starboard side of the bow, so that the mooring ball can only reach half-way to the opposite hull. Then feed a dock line through the actual mooring ball eye and back to the same cleat (you might have to pull the mooring ball up out of the water to reach it). And finally cleat the dock line so that the mooring ball is secured between the two hulls in a way that it can't reach either one. This way the boat can only swing around the mooring ball, not swing from the end of the pennant, plus can't bang the hull of your boat.
