Gav and I swapped boats for a hour last year, and we both commented then that my rudder gave more feel, and his felt stiffer. (Said with a straight face)
On my new boat I had to push quite firmly to put the rudder on. Once on, you didn't really notice it, but that extra friction must be causing a lack of feel/ feedback. So this is a guide on how to loosen your stiff rudder.
Part 1 Gudgeon vertical alignment
With the rudder off. Take a long straight edge (spirt level works best), and check the vertical alignment of the gudgeons, by placing it against the sides of the top and bottom gudgeons, on both sides. You may find that they don't quite line up. With my level on the starboard side of the top gudgen there was a 1-2mm gap to the bottom one. This tells you they are not vertically lined up correctly.
If you put the rudder back on and look from the side you will see it will rest one of the gudgeons and have a gap to the other. Mine rests on the bottom one, so I would think this takes most of the load. I therefor removed the top one, and with a drill elongated the holes in the gudgeon by about 2mm, so I could now re fix in correct alignment. If your lucky this will be all you need to do so try it. If not move on to part 2
Part 2 vertical angle of gudgeons
Lossen off the top gudgeon, and lossen off the 4 nuts on the bottom Pintel on the rudder stock, wiggle them about a bit to make sure they are nice and free.
Now comes the trial and error bit. With them both loose you should be able to find an angle for them both that you can put the rudder on and off with little friction. ( you may need 3 hands for this bit, so get the wife involved)
Slowly tighten the loose gudgeon, while continuously putting the stock on and off. I found that only when I did the final tighten of the screws the rudder went stiff again. Turns out it was pulling the top of the gudgeon into the top curve of the rudder mount. So I packed the top half of the gudgeon out with Mylar tape to get it to sit at the correct angle.
Then find the correct angle for your bottom pintal and tighten the nuts, and hey presto hopefully your stiff rudder problem is cured.
