Hey guys...just stumbled onto this thread a little late...scooby, I was wondering what's bad about the shape of the rudders in the Cirrus Evo shape shown in the picture above?

I'm asking because I often sail in the local shallow mud pit and am trying to learn techniques to make foils which work as well as possible with shallow draft...and that shape would seem attractive to my inexperienced eye. Not the daggers, though, which seem perfect for oil drilling.

Also, do people prefer the lighter moments on those foils with the pintles roughly in line with the quarter-chord? Or are more forward pivots, encouraging better trim steering, preferred? (Yes, these questions are being asked by a reforming dinghbat...)
