well since you have been using the floating lights at the dock, with no luck, and now your going to fish from a boat, I would say use the same lights, and see if they work for you, way back when I did a little night fishing we only had floating lights or coleman laterns hanging from a rod over the water and it always worked, try it, and if possible try to fish with someone who has been on the lake where you want to fish, if they can not be found, please be carefull....
