LOOK on the californian forum.* There was a discussion about rudders and sizes on a 34LRC.* You don't mention what model Californian you have.* In the rudder thread it was pretty obvious that some variation exists in rudders between model years and even within the same model year.* My boat is on the hard right now.* I believe by memory mine are 14" high x 10" wide.* I can check that on Wednesday when I'm working on the boat, if you like.* My rudders are somewhat rectangular, others are more rounded.* I have a picture of mine but unfortunately they are in the camera in the boat and not on my computer.* I bring it back Wednesday evening as well.*
Before you spend to have something custom made, look here:* http://www.deepblueyachtsupply.com/m...ering-hardware
I have had no experience yet with these people, but will have by the end of the week if they ship my cuttlass bearings and zincs I ordered this morning from them.
My rudders*are very close or identical to the spade shape model 10r20SS1.2
Others Californian ownershave what* looks like the standard* shape.
I don't know what my shaft size is but you should have the stuffing boxes to measure.
There is a lot of latitude in rudder designs that will work.*
