Navigating the bay depends on boat type. You mentioned a dock, so may we assume you have a large boat? South bend launch at the park. Turn left and hunt. You will be limited to the main channel. Best bet is to go out on low tide and you will see the finger channels that will get you into the marshes. Do not go out on a falling tide, I won't drag you off.You can anchor in the channel, away from traffic lanes, and kayak in. And, hunting from a boat is a waste of time. Best shooting comes from spots absent of all cover.
