Dave,

He has a MK I G-Cat, the original model was made with one-piece hulls (actually, I believe there is a seem along the keel that is glassed over) and deck-sections for the top. It was the first catamaran to be built this way.

I'm coming to NC Sept. 3rd-6th and could possibly meet up with you. I've found all my G-Cat literature which illustrates how the jibsheets and barber-hauler are routed, how the rigging is attached, etc. However, it's larger than 8.5x11 legal-sized paper, so scanning is a bit of an issue. I can give you copies of everything but the "construction manual", but if you have a way to copy or scan it, I could bring it as well.
