I've got a pre-1972 sunfish rudder that I'll sell for $65. I'm in Raleigh, and could send it with a friend to Lake Gaston (he goes there every weekend). Call me if you're interested.
New style (post '72) rudder and daggerboard for sale. Good condition, probably need some varnish. $150 for the set
I also have a trailer that will work well for a sunfish. It was used for a little bit bigger boat, but will work for a sunfish. Galvanized wheels, good tires, and bearing buddies...
