If you fish with a buddy then swap turns fishing or operating the trolling motor. If you fish alone, in a 30mph wind I'd stay away from shallow water or any kind of rock. Regarding the sock; I've used a sock in saltwater and they only work if you don't mind going whatever direction the wind is blowing. They do just fine if you're 20 miles offshore. On a lake they could easily make it impossible for you to avoid obstacles or other boaters while you're drifting. Keep in mind, at Kentucky if the dam operators are pulling water you will have current underwater and the sock will try to go with the current. And good luck getting your boat back on the trailer if you have a 30mph crosswind at the ramp.
