[C320-list] White Rudders

[T. Scott Thompson]

I've heard this theory, but as Rod says, I heard it was about storage on 
the hard.  What's more, the way it was told to me it was only an issue 
in freezing conditions where the dark color might lead to more daytime 
heating and thus more freeze / thaw cycles of water that manages to 
intrude into the rudder.  Some people cover their rudder with white 
plastic to deal with this, but not very many from what I've seen in 
yards here in Maryland.
