OK so what your telling me is that nacra put a rudder system on all of their cats that is not functional? Somehow I dont think that they would do that. the U-joints that you are speaking of are not actually u-joints, but are welded together solid. Is it possible that I have something flipped the wrong way? The adjuster on the crossbar is on the port side, is that corect? The way it is set up now it seems to center the rudders when I let go of the tiller. I dont think I could turn the rudders all the way to the side. At least not without breaking something.

As far as the small block on the haulyard, I get what your saying about it helping to tighten whatever, but where does it attach, etc. I guess maby i'll have to set up the boat in my driveway this weekend and figure it out myself.

How do the bungees attach through the tiller tube? what size? I have some thick bungee but it wont fit through the tiller tube. How are the attachments made at the front of the tubes?
