Dratz - i have not come up a weedless surf rudder but the places I surf the weeds are not a huge issue. I like your idea of a rudder with a notch in the front. I imagine DK could make one. Of course then you might need to place a weedguard on the hull to protect the new rudder gap. Do you have any idea what the pros were using for rudders in the doctor?
