Mark,
I was halfway joking honestly. You see, I have a fundamental problem with carbon fiber. While I agree that its a wonderful material to build with, a lot of people that produce structural parts don't understand how to implement it properly, leading to many disasterous failures. It is particularly fitting in the sailing industry where my experience has shown that carbon is used to fabricate under-built components that fail slowly over time.
But if you want to take a stab at it:
Theres the front crossbeam.
Notice the deflection of the mast. It is carbon fiber and weights about 30 lbs all rigged. It should NOT be bending like that
