Snow....We sell a 100% Chromemoly Rudder designed for the Flatbottom that we have been putting under our boats for quite some time. It is a smaller version of the wedge rudder and we have put them under River Boats up to 170mph Top Alcohol Flats. If you need any more info please E Mail and I will help you as best I can. Maybe some of the people on the boards that have purchased this rudder can tell you what they think.
Thanks Dan
