Thanks Jim, I think the "bite" is the reduced turbulence from a few things such as covering up of the rudder stock gap and also the fairing of the top of the rudder to the bottom of the stern.
Yes, I remember some poster saying to "just get another boat"...it was not a really hard project
, maybe a bit longer than 1 week. Just took a bit of thinking ahead of time.
I did not notice the steering to become any heavier after adding the 2" to the trailing edge. Instead, the boat can turn in a much tighter circle/turns than before. Also quicker response from rudder under sail.
