it was a pretty simple add on of a extra dry piece of 2x3. Obsolutely without engineering ... more of a pure art form from looking at a few other rudders and comparing how gross the j30 rudder was. I will measure it once they finish the painting, put a tape on it and do a front view. the experiment 23 years ago was just to add it on, and if it was a problem to sawzall off however much. weight was not a consideration.
Nearly all my sailing was off beavertail where the wind is stronger and only in the bay if it was too rough to go out.
I have to admit in light wind when you would normally not mind a bit more of weather helm it may be a touch too neutral, but as the wind kicks up and sail trim doesn't seem to do as much as you would like ... it does help. We haven't been getting a lot of light wind days for the last couple of years here, but when we do i have to concentrate on the woolies, and not so much on feel, on tight haul.
I cut a set of keel templates and will see if any of those precut radius's come close to the leading edge. one of the lower ones might be close.
My keel templates did ok on 505 ... and gave the bottom guy a good idea of how to fair the dent at the bottom from hitting a rock when in Newport. other than that no real need to make changes to the keel for phrf competition down here. this was the first time we templated it since it was new.
Naples is a social racing circuit where low budget programs keep the retired guys active.
