Have you ever tried this?

Sunday We were fishing the area out from Shell Island and weren't doing that great and looking for more action. It was about 3 pm and the tide still coming in. The wind was from the west/northwest and we had a pretty good chop. I thought we would try our luck drifting eastward over the grass flats starting around the channel at marker R8. As soon as the shrimp hit the water my wife had a strike, it was a yellow tail jack about 2 lbs. After landing that one I ran back upwind and dropped the anchor which put us just outside the channel between marker R8 and R10a in about 7 ft of water. We were fishing with live shrimp on a bobber. Now this was Sunday afternoon and traffic on the channel was really heavy, every time a big boat came by action would really heat up. It seemed that the fish were just waiting for those huge wakes surge out of the channel on to the spoil area so they could ambush their prey. When the boat traffic settled down so did the fishing action. We caught Yellow Tails, Macks, Trout, and Cats.
