Quite a while back someone from Oz described how they finished the keels and
skegs of their kayaks with epoxy laden with Silicon Carbide, the stuff one
grinds telescope mirrors with. I quote "The ramp doesn't mark our boats.
Our boats mark the ramp."

Thanks guys,

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

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.

What glass are you describing?

You mean, "dense"?
