I have recently purchased a 1979 Catalina 25 fin keel. The tiller has been snapped off, I am in the process in making an order for various other stuff and want to order a new tiller. I looked at the ones here, but have no idea which one to order. I haven't been out to the boat with a tape measure yet, so I was hoping you guys could help. I am looking at the C and D models. Any help would be appreciated. I will be sailing in Missouri lakes and want the most cockpit space so I'm leaning towards the D model. Again thanks for the help and wish me luck.
