Half of Auckland mentions they used to sail a D28 and ask me which rudder I have when they hear I sail one. The popular take is that there were multiple variations made to improve the original rudder, many of these being DIY efforts. From what I hear many were extending the leading edge forward to give it some balance as the design I have is pretty much in line with the pivot point.
I can't find much trace of the Davidson 28 association as it seems to have faded away before I acquired mine. Does anyone have any info on what people were doing with rudders? Drawing, patterns, moulds, etc?
Any other knowledge about the class is appreciated too!
