Kevlar for the hull, carbon fiber for the mast, on a sailboat.

Think you will find carbon is on allocation and it ain't cheap.

Try double bias glass and epoxy.

Yeah, use Kevlar instead of carbon.

Thanks guys,

I've decided against the carbon fiber and to go, instead, with the
glass/epoxy/graphite option instead

Did you look at plywood with a glass-epoxy skin... I'm willing to bet
that in comparable panel strengths as compared to an all fiberglass
hull, this will be lighter and cheaper... LOWES has exterior Luan ply,
5.1mm, for roughly ten bucks a sheet... I just finished building a 7.5
foot dink this way and you can pick it up with one hand...

A thick graphite/epoxy mix, spread liberally on the bottom, is really good.
Put it on as a finish coat, NOT to wet/fill the glass.

Even better, the dories stored on cobble beaches of Grand Manaan Island are
sheathed with UHMW plastic panels. They just slide them down over the
rocks to launch, winch out. The problem is that this stuff doesn't adhere
to anything, and must be mechanically fastened.

A double layer of fiberglass and the volume of epoxy needed to
completely "wet" the fiber is VERY heavy
the luan & epoxy+ graphite would be good and light and wear well
or you could go with (from inside to outside bottom) carbon
fiber,ultra dense foam, kevlar, graphite. very strong, VERY light
wears like armor AND INCREASES FLOATATION

What glass are you describing?

You mean, "dense"?
 >> Stay informed about: Carbon Fiber 

no i ment heavy as in weight. there is not a fiberglass boat that is
light when compared to other composites or even okume(sp) plywood once
the fiberglass has been built up comparable strenght
