> The Olson 30 class adopted an eliptical rudder back in the 1990's or so.  The change was made to provide more control on a tight reach.  The surface area of the rudder was the same as the old one in an attempt to alleviate concerns with PHRF.  There was no difference in speed upwind/ downwind.  Boats with old rudders won Nationals against new rudders.  Didn't make a difference, PHRF knocked us 6 sec if we made the change.  Luckily we did not have to race PHRF at that time.

Much better to take the rudder to Driscoll in  San Diego and have them template and fair it.   If you are really seriious have them do your entire boat.  I tried to buy one I think they did, but I was to late.  It won the around Catalina Island race and it was totally tricked out. Don't remember the name.  Maybe someone on this list has the info.
