Here in the great white north the concern is the water freezing and splitting the rudder.  The surveyor concurred with that reasoning.  Good old fresh water has it advantages but cold weather has its own items to be concerned with.  We haul, winterize and cover but we don't have to worry about Hurricanes and electrolysis (at least as much as salt water).  My shaft zincs are pretty much only a shaft stop.

Thanks for all of the input on drain holes.  I think I have my game plan.

When we bought ours the surveyor gave cautionary guidance that water in the rudder was bad since it could cause the metal web inside to rust.  Eventually this could result in the rudder twisting freely on the post or even falling off.  His guidance was that the only good way to fix the problem was to have the rudder rebuilt.  He told stories of some people drilling drain holes but wasn't convinced that all the water ever made it out.  Imagine trying to dry your laundry by just draining the tank and opening the lid of the washing machine. We were sufficiently scared by the possible consequences and had the rudder rebuilt the following winter.  In conclusion the steel web and welds were perfect and draining may have been sufficient - but for how long is anyone's guess.  Some people have a hard time sleeping on the hook.  Instead I have nightmares about killing people when the rudder, mast, or keel fail.

Here are the pictures that the fiberglass guy took during the rebuild.  They should help you when determining the internal structure of your rudder and where to drill holes.

    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.
