 Does this mean that there is something wrong with our (A30) rudder design 
 that Carl corrected with later designs? What is the fault?

Hey,
I think the advantage of the squared off bottom rudder is to get more square 
inches of rudder surface down deep as possible, to get turning surface as far 
awy from surface trubulance as possible.  The disadvantage is that if you 
ground, the rudder is more susceptible to damage.  Personaly, on a cruising 
boat, I prefer the rudder protection of the round trailing edge design
