Neil:
There is probably no one simple answer to your question with water
intrusion in a rudder....a hole or two drilled into the bottom of the
rudder is always a good place to start.
In my case, my rudder was rebuilt by the original owner just before I
acquired the boat. Nevertheless, there were several voids in the rudder
that didn't get filled in the rebuild.....water intrusion is from the
rudder post as it enters the rudder.....so with a moisture meter we
located the voids (there were 3, 2 on the starboard side and 1 on the
port side of the rudder).....by taping the side of the rudder with a
small brass hammer, we could fairly accurately figure out the location
of the void inside......I then drilled one hole into the side of the
rudder where I thought the bottom of the void was.....if right, water
would appear.....it did in all 3 cases.....drilled the bottom holes
upwards approx. 40 degrees......then drilled 3 holes to what I thought
was the top of the respective voids.....down on 40 degree angle.
Water drained from all 3 bottom holes.....let the sun hit the rudder for
a few days to dry everything.....no sign of any water weeping from the
bottom holes....plugged the bottom holes with thick wax and then poured
or rather injected West System resin down the top holes until the voids
were filled with resin......faired both holes with thickened resin.
Every 3 years I drill a hole in the bottom of the rudder to check for
water......dry after filling the voids and annually prepping the rudder
post to rudder with 4200.

One of the items in our new C&C 35, Mark III was that there was
moisture in the rudder and the surveyor suggested drilling drainage
holes. Anyone want to suggest the location to drill? We hauled out
last night and I am going up to the boat to disconnect batteries on
Wednesday. I assume that the drainage holes will be in the lower
quadrant of the rudder. Should they be in the side or in the bottom
surface (or does it really matter.
I never had to do this on my Redwing 35 so this is new to us.
