This may sound like a silly question but have you checked to ensure that your wheel
lock is not partially engaged, or engaging as you turn the wheel
? (I have seen this happen.)
Next, have you checked to see if you have anything hanging up on the rudder itself? A piece of debris, or a line from an old fish
trap or net could be lodged between the underside of the hull and the top of the forward edge of the rudder (I've seen this as well).
Next, check to see if the follower nut on the packing gland
for the rudder tube is intact and not over tightened. If the packing has given up and even a small amount of rust has developed, that can cause binding (although that's pretty unlikely).
If none of these are the matter, check your cables
to see if you might have a couple of broken strands that are hanging up in one of the shieves before the quadrant. Simply looking down on the quadrant from the cockpit
probably won't reveal that. You'll have to either stand on your head
to see under the cockpit deck
or reach under-gingerly-and run a rag along the cables
forward of each sheive--there are four, while an assistant turns the wheel s-l-o-w-l-y. One of the shieves might also be hanging up or you might have gotten something jambed in the cable system forward, near the base of the binnacle, that's getting pulled up into the works there as the wheel is turned.
If none of the foregoing, try loosening the cables entirely, freeing them from the quadrant and connecting your emergency
tiller to see if you can turn the rudder freely without any interference
from the steering system. If so the failure's in the steering and not the rudder and if so, you'll need to remove the compass
to get to the steering gear
beneath for an inspection
. You may have a damaged drive chain or a broken sprocket with a loose gear
tooth sculling around in the works.
The good news is that repair parts
