Have you heard of Marine-Tex?
How about building up the rudder at one point so that it is tight in the frame when down? This would be a mound about the size of a quarter.
Oh yeah!
LOTS of Marine-Tex on these hulls and rudders to smooth out all the dings and rash. Good idea. Thanks! <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
