I was out by that green buoy off of Catawba got 36 nice perch, noticed a boat close by that had his motor running the whole time he was there, they were picking quite a few perch. They eventually pulled up and went in, I don't know if they were running out of fuel, had carbon monoxide poisoning or got their limit but they pulled anchor and left. They seemed to be catching more fish than us, maybe that motor trick does work. I have heard that using two anchors helps a lot to restrict the boat movement(don't know how they keep from sinking their boat with all the wakes and stuff?) this would be safer as long as your motor doesn't smoke too much!
