A large part of the Skimmer's action is caused on the ending movement of each zig or zag as the tail-weighted back end of the ima Skimmer stirs the water wildly causing a large boil. So every time that the Skimmer zigs or zags left or right, the final movement of the weighted tail stirs the surface into a large boil, and the Skimmer slips out barely ahead of the boil, just like a desperate baitfish narrowly escaping a bass's lunge. The Skimmer's action then becomes a non-stop series of ever-widening boils emanating behind it. It's like having a school of surface-feeding bass on the scene, all boiling the surface behind the ima Skimmer's tail. If there's ever anything that gets a non-committal bass to bite, it is other bass feeding in front of it - and that's the competitive feeding cue that the Skimmer's tail-stirring movement sends out to all bass within range of sensing the surface-feeding boils trailing out behind the Skimmer.
