Our Canoe Anchor Bag is a heavy sturdy mesh bag with handles. You tie a rope through the handles, fill the bag with rocks, and the handles help hold the rocks in the bag. The Anchor Bag drags on the bottom of the lake or stream. The weight of the rocks keep you from drifting when fishing. Remove the rocks and use for many camp chores. This item is invaluable. Made here on the edge of the Boundary Waters Canoe Area, right here in Ely, Minnesota.
