I see your point in that instance. I just don't think it is a realisitic situation out here and having to use 30ft of chain day to day would clearly outweigh any rare instances I might find myself wanting to anchore up like that. Most shore spot anchoring is done in just a few feet of water in protected waters. Maybe if I were to get into Scuba or more serious snorkling but in that instance you really should have a lookout on the boat anyway. Not sure of the dimensions of my chain but I have yet to come loose in a fishing situation yet. Not to mention fly fisherman tend to drift more as well.
