This is my rendering of a homemade anchor design. I think the original was made in the TVA pipe shop at Muscle Shoals, AL. THey would use stainless steel pipe and fill with lead to the desired weight. Lots of fishermen used it on the Tennessee River which has rocks, logs and mud on the bottom. It's easy to retrieve when jammed by pulling it to the rear. I have a piece of PVC cut to make a Nucanoe version sometime in the future.
