Thanks for the reply. I guess I didn't state my first question with enough background, so let me explain that I have a homebuilt boat, (I picked it up from someone else) and the rudders were originally mounted at about a 30 degree angle off of the waterline. I have repositioned them to approximately 90 degrees from the waterline, but have yet to sail it as changed. So, I am assuming that I need to get the rudder rake situated first to an optimized "feel" then think about adding T-foils. Basically, the addition of the T-foil does not affect the weather/lee helm characteristics of the boat does it, or does that bring in a whole new rudder rake set-up?

Secondly, should the T-foil be at a right angle to the foil, when viewed from the end, or should it be placed parrallel to the rear beam in the case of canted hulls?


Many thanks,

Rich
