Stewart,
I'm probably telling you what you already know but the Glass/foam Paper Tigers come in at min weight without the use of carbon. That is complete platform weighing 50kg.
Ready to race would be around 70kg.= around 150lb

A couple of years back all carbon/kevlar platform cost $4,500 Aus . That may have gone up a bit but still a finished boat would be nothing like $15,000 US.

Hell, I've got a Paper Tiger mould and there is 4.5sq metres of surface area per hull. Anyone out there wanting a $15,000US PT should give me a call. But it may be in their interest to do the numbers first.

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!
