Comfort Zone. That's something that I never could get my dad to change. He knew a few spots on KY lake that he had fished for 30 years and I never could get him to fish new spots. I liked to experiment when I was younger. As you get older you get more settled in your ways. But one needs to try new things to remain young at heart.

Deep water fishing is so much different that casting a crank bait at visible brush along the shoreline. It takes knowledge of where the fish will be and then it takes CONFIDENCE in your method. 20ft is not much deeper than your boat is long? It's only twice the length of my fishing poles. I crappie fish these days but in my younger days I started deep water fishing. I was back trolling deep water in Canada for walleyes and huge Northern Pike. I can remember fishing in 35 ft deep water at Patoka Lake when it first opened. I fished with the shad shaped plastic grubs with the swim tail. I used a heavy 1/4oz jig head and caught fish in deep water. It took me a long time to learn to fish worms for bass. I guess I fished the wrong spots as I never caught bass for the longest time on plastic worms. Then I discovered Dr. Juice and my catch rate sky rocketed. My last fishing trip at Barkley Lake with my Dad I was catching bass left and right and dad was almost skunked. I had confidence as I caught fish. I had finally learned to feel the bite and to tell the difference between a bite and a rock on the bottom. Once you get the feel and grow your confidence the deep water fishing becomes more comfortable. This is even more true in very clear water lakes. In Canada fishing on the Canadian shield the water in those lakes is crystal clear. You can see 50ft down into the water. Ive never fished Bookville Lake but I would image it's somewhat like fishing the clear water lakes of Canada.

Time out on the water will help instill more confidence in your fishing ablities. And nothing instills confidence in your fishing like catching a mess of fish.
