Re: Strip: 3.2 oz Questions *PIC*
In Response To: Strip: 3.2 oz Questions ()

: I am about ready to glass the hull on my Night Heron with 3.2 oz
: glass from Thayercraft and I had a couple of questions about the
: layup. I am going for a reasonably lightweight layup, but with
: enough strength to not worry about it. First off, should I do
: two layers of glass inside and out of the hull and deck, or are
: there areas that I can get by with just one layer? Second,
: should I wet out both layers at once, or just one at a time with
: no fill coats in between? Thanks!

I can't tell you how strong it is but I just finished laying up my guillemot a month ago with the same glass. I did two full layers wet out at the same time on the hull and deck outside, one layer on both insides with a second layer where the hatches are on the deck, a second where the seat and feet go, a second on the hull under the two hatch locals, and a third layer at the back of the coaming area.

I can tell you that wetting two layers of the 3.2 at once was a joke without a seal coat! Just take your time to get every wrinkle out of the cloth on both layers before wetting out. The guillemot and night heron are close in size so here is the amount of resin used for two full layers... hull = 27oz, deck = 24oz. I used a single fill coat on the deck and hull brushed on and have sanded into it in areas and not gone through with 80 grit on a orbital total resin used on fill coats... hull 18oz, deck 12oz. The 3.2 is awesome for fill coats due the the tight 40x40 weave, even when I seamed the two halves together, only one fill coat brushed on.

Good luck hope this helps

btw... I can't see the glass at all under the resin it looks as though I just brushed the boat with resin and that is it!
Also as for the strength it feels stiffer than a production current designs boat so good enough for me!
