On Reelfoot, your chain is dragging the bottom, over a few logs, etc. Does it spook a few fish? Probably, but they return rather quickly. I make repeated runs quite often. If I'm in a lake where I'm fishing planted brush piles, I use socks so I don't destroy someone's hard work. I've had chains, mushroom anchors, and window weights behind my boat. It doesn't seem to bother the fish I'm catching.
