Hi Haventbeensolucky,
Welcome to fishingreminder.
I am sure someone with local knowledge will be able and willing to give you some tips for rigs and lures.
I am interested in this boat channel. 9 feet is not very deep. If it is even slightly busy with boat movements, then there is a good chance there simply are no fish. Have you tried areas where there is few or no boats? Even a small boat is going to sit 18 inches maybe 2 foot in the water which puts it 7 feet from the bottom. A fish swims past at say mid level and that puts the boat only 3 to 4 foot away. No fish is going to stay within a few feet of a boat motoring along.
