So the general consensous is that a fiberglass boat but with a carbon mast would be a better than a carbon boat with cheaper mast?

Are you sure that 1 layer of fiberglass will be enough? It just seems that it is going to be prone to being hurt, what is normal for factory built boats?

Thank you for all the info Nick, I am sure I will be looking for more as I go on.

I have been working with a CAD program and have the hulls designed, I am sure that I have a long way to go on them but I have the general shape designed?

I read somewhere that people have used masts off old Nacra's to build the beams? What are some other ideas for beams? Could you use an old Hobie mast or are they not stiff enough?

Once you go cat you never go back! Nacra 5.2 (Elsies)#1499, running an inter17 spin!
