[rudderless22]

I just acquired a Columbia 22 with steering problems. It has a homemade rudder and it doesn't work well, the boat won't tack! Can someone post the dimensions of the original so I can modify it if possible. Or better yet, does anyone have a spare lying around they want to part with? Never had a boat with a motor well , how does this effect steering and what do you do while under sail, and having it in the water has got to slow you down. Pulling it out and stowing sounds like a lot of trouble. I've seen picts with the kicker in back, was this well added? Help!
