[Public-list] mast compression

[Mike Lehman]

That is the right spelling George. It would be great deck core material, as 
you and I have already found out. To learn more about this stuff see:

Patty,

It sounds like you're talking about deck compression.  I was thinking
about this, and think that Coosa board (Is that how it's spelled, Mike?)
would be a good core material under the mast step.  It's a
foam-and-glass plywood replacement--light and rigid.
