Re: Build Fiberglass Rudder
It looks like RudderCraft (used to be IdaSailor) sells a kick-up rudder for this boat for $599, including a tiller.
They CNC their rudders out of HDPE plastic. Splitting is never an issue and they are fairly light and have a nice profile.
If you don't need the kickup feature it would be worth asking them for a price quote on a fixed rudder. I'm guessing it would get inexpensive enough that I personally would look for other projects (but I don't especially like working with fiberglass).
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
