@goldensky - I use a drag chain invention for my kayak. I inserted a large linked chain into an old bicycle intertube then wrapped it with some really wide electrical tape.
The chain has to be wrapped good to reduce noise and prevent damage to other things. For the anchor line I used a cheap retractable dog leash.
It's perfect for pulling in and out the line. The leash is attached to the frame of my seat with a small dog collar.
I've only been out with it a few times but it's worked nicely so far. If the water gets too rapid I can just unclip it and move on or if need be, just cut the cord. It's not that expensive or difficult to replace.
