I'm usually a lurker here, but there's been some things in past AYRS journals re rudder ventilation that might be worth checking.
One is a few horizonal fences on the rudder near the static water waterline. The other is to sweep the rudder forward a few degrees, this could be tricky rearranging pivot points for balance etc. but worthwhile if it keeps your rudder unventilated.
Have really enjoyed your posting of real experiences.
cheers,
