I agree with Robert about bows and anti dive plates. 

My Elementarry rudders don't ventilate at 18 knots, I suspect that Doug's problem is more shaping and fairing than inherent.  However, the Farriers and the 18' skiffs both use small plates on the leading edge to prevent it, so if they still do it when faired and shaped (NACA 0012), then add them.  Another solution is to rake the blades forward slightly.
