Just saw your post and that no one had bothered to give you some info.
First off, working with glass, carbon, kevlar and resins is both
expensive and really toxic. I would figure unless your folks are
people who build stuff themselves, they won't be into your project.
If that doesn't frighten you, a place to find out about these
materials, including books, is Fibre Glast Corp.: 800 821 3283. Again,
don't think this is easy.
My suggestion for your summer, something I wish I had learned, is to
make your own garments for on and off the river. The money you'll save
can go into boats and helmets. A company that sells patterns and
materials for everything from bunny suits to bivy sacks is Rainshed,
541 753 8900.
