Carl,
JUst as side note.
I was fortunate enough to attenbd a lecture by Meade Geogeon
a few years back when he cam eout to Aust, I was building a 32ft cedar strip cat at the time.
He went thru a lot of the research they performed with NASA when they were designing wind turbines. They found the most superior material when it comes down to cyclic stresses as as experienced by turbine blades (and boat hulls alike)
Is wood laminate with 6% carbon.
This was after they tested all manner of materials both natural and man made.

Regards,
phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
