Hey Faster, Thanks for your post.
Yes, it's stiff / resistant at the dock. By heavy I mean it's not light and free and to move and it takes more force than I would expect to get it to move. (It's hard to describe the amount effort required, I guess a 2 year old child couldn't move it, but a 3 year old could). I've been on an other Catalina 27 and the tiller moved freely.
Would love the problem to be a tiller lock... alas we don't have one!
Your post made me wonder if there is some homemade / oversize / incorrect bushings down in the rudder post sleeve.
Sounds like it would be job for the tidal dock to investigate, in the mean time I think I'll order the proper washer / bushing from Catalina direct.

Unless you can suggest a Canadian source?
