[quote=pharlan]I thought I had read where if you filed the trailing edge of the rudder very lightly on just one side at about 40 degrees that it broke up the cavitation of the two flows coming back together and reduced vibration (from this cause). Can anyone help to verify this? Or to privide what the trailing edge should be (blunt, evenly angled, rounded or one sided)?
I have another person with the problem and I remember reading that somewhere regarding cat rudders and would like to verify this.
Thanks. Paul[/quote]
