An addition to the earlier comments. Toss (not cast) the jig into the drift (about 10-15 feet depending upon drift speed). Then jig. I usually get the strike as the line goes past the boat. I believe that this is because by using this method, you have the jig bouncing in the same general area a couple of times and then when you drift past the vertical spot, the jig begins to move away with the drift of the boat and it will trigger a strike
