I pulled the rudder off Rhapsody and brought it home for the winter to see if it was wet, and dry it out. I drilled two 1/4 inch holes about 4 inches into the core from the bottom. All I got was dry balsa sawdust once I got through the fiberglass. There is no sign of the rudder splitting or cracking anywhere.

I assume this means I have a dry rudder, can fill the holes now and won't gain anything by letting it air out until I'm ready to launch in the spring. Can anyone with experience in this area confirm this?
