I am having a place diverter installed and would like to know if any of you would suggest installing the rudder? I have no experience in this matter. The current configuration does have a rudder but I don't know how much it contributes as I have never been without it and am unable to compare. Any feedback would be much apreciated. Thanks. FYI-1977 Challenger 19' and do 99% of my boating at the river near Oxbow/Destiny's Riviera. Thanks...
