LOL...OK I see your point Bob, the picture shows a flat-bottom boat. I think we are on the same side of the fence. I look at the rendering as a basic instructional guideline for installation. The rudder post is plumb and the base is to be cut flush to the outer hull. Flush can be 90 degrees as shown...

Re: propellers rake and attitude
On a windy day walking with a flag pole, I place one hand low with the other high, close to the flag. In my mind, the same logic applies to a rudder.

Yes, to avoid rudder ventilation a rudder plate extending out from the transom, or a foil incorporated on top of the rudder seems to be part of the design...I'd think trim tabs could also work.

I believe the issue was the rudders were too far back from the props, I think you want to keep that relationship between the two very similar.
