Jim, To balance the rudder I cut about 1.75 inches out of the front of rudder just around waterline making sure leading edge would slip under hull,I`d have to take a look to remember exactly.This moved Gougens or pintles(which ever)back. I also added about 2 inches to the back slanted top part of rudder to give it the same appearance as before. I didn`t touch leading edge of rudder thereby not altering the foil shape.I think I could have increased the measurement by half inch or so ,this would have put the leading edge just forward of the pins.(terminology is bad)My helm is still heavy off the wind by times and my Autohelm 800 has a hard time keeping course. I think there is a bit of guess work involved . Maybe if you could find a spars rudder to try it and do a bit of experimenting .I`m bad for frigging with my boat, I also put a retractable bow sprit in, All I need are a couple af assy. sails,but my wife thinks the hole in the water has enough money poured in it now.
