Question?

Being a new kid on the block, why the one 20 Oz. or two 10 Oz. Layers of glass on the bottom?  I understand the need for protection from rocks, stumps, etc. as you are moving downriver.    Is this because the faster water & big rocks you would experience in Western Rivers, Colorado, Yellowstone, Snake, etc.

Where I am, in Mchigan we don't have much fast water, gets kinda squirley in the spring runoffs but nothing like I've seen in pic's in magazines, books, etc. I used two layers of 6 oz. on my stripper canoe and have scrapped it over rocks & stuff and seen no damage to the glass to peak of.  But, I have yet to smack any rocks moving too fast.  I would appreciate some insite on this subject.

I would either use 1/2 or a layer of 1/2 with another layer of 1/4 over,  with 21 oz triaxial on the outside and 12 oz or 10 oz s-glass on the inside.  My work boat has a3/4 bottom and its bomb proof.  Look up Raka fiberglass out of florida for the glass.  Some graphite powder in the last two or three coats of fill in epoxy will make it real slick.

I built mine with 1/2" ply, with 3 layers of 10oz glass on the outside, and 2 layers 10oz on the inside.  Might be overbuilt, but have yet to knock a hole in the bottom.

Hello Ryan, 

1/2 in fir plywood with 20oz tri-axel fiberglass or two layers of 10oz glass cloth on the outside is the time proven bottom.  Ray Heater has been using that combo for years.  We do the same. 

Ray, chime in if you are here.  I think Ray and Cyrus also use Z-glass on the inside.  We use Durabak18.
