I'm not trying to make a point here, just an amusing story about anchors. When I was a kid, every lake fisherman worth his salt had a couple of anchors, usually just cement filled coffee cans with an eye bolt or a heavy wire loop to attach the rope. My father came across a source of free lead and poured a couple of one-pound coffee can anchors which seemed like a good idea at the time. After anchoring up on the inaugural trip and fishing for a couple of hours, it came time to weigh anchor. Those two lead anchors had settled so far down into the lake-bottom ooze that it took a long, long time and much rocking of the boat to pull them up and out of the mud. We quickly went back to the concrete-filled cans. I don't recall how much those lead anchors weighed but they were much, much heavier than a comparably-sized concrete anchor and just kept sinking slowly into the deep mud of the lake bottom. I made anchors for my float tube from a couple heavy ball sinkers. I carried them around for a while but never did use them. I've always found it easier and more convenient to hold the float tube in position with the fins and found a definite advantage in being able to turn the tube quickly around, and not having a couple of anchor ropes out there to entangle the line and the fish during the fight.
