While watching a fly fishing program on TV this morning I noticed that the drift boat anchor was a large "knot" of chain instead of the traditional pyramid style anchor. I have seen the spiked cylinder style before but not the chain. Have any of you used this style of anchor? It may have been more like a dozen or more 12" lengths of heavy chain on a "D" ring than a knot attached to the regular anchor system like a traditional pyramid would be. Wonder how something like this would work in the Kenai?
