Hey All,
I came accross a method for devising a break away anchor system to prevent the possiblity of being stuck in an undisirable situtation. The system was simple. If you have a folding anchor, turn it upside down and attach the rope to the bottom portion of the anchor(by the forks) with a zip-tie. This does two things 1. The anchor is in a better position to grab the bottom. 2. If you need to pull up an anchor that is stuck, all you have to do is pull hard enough to break the zip-tie to get more slack in the rope at the site of attachment. I personally haven't used this method, but it might be helpful for river or saltwater fishers.
