No gouging. You use a Pinless Moisture Meter like this: http://answers.canadiantire.ca/answers/9045/product/0574572P/mastercraft-mastercraft-pinless-moisture-detector-questions-answers/questions.htm
Or these: http://www.electrophysics.on.ca/e_index.htm You don't use the meter for an absolute value, instead you use the meter to compare an area you know is dry to one that is questionable. I don't know anything about the construction of the rudder on the 24 but I'll assume it is a fibreglass shell with a foam core and a structural web inside welded to the rudder shaft. Me, I'd drill a 1/8"hole straight up through the bottom edge of the rudder, using a long bit so you can get several inches up into the foam core and see if water comes out. If there is water and it comes out clear you shouldn't have too much to worry about except what damage may already have been done through freezing. If it comes out rusty and black I'd be concerned about the condition of the internal structure. Plug the hole whit epoxy before you launch the boat. Re drill the hole in the fall when you haul so the water can't freeze in there. Ken H.
