As a first time builder and glaee-epoxy-using-virgin, I very apprehensive about screwing up this phase.

I'm looking for the specific trade offs of different cloth weights.

Nick's book has a light weight (all 4oz cloth) and a standard layup (6oz). I have recieved emails from fellow BBS members suggesting a mix. specifically, 6oz on outside of hull and 4oz on the other 3 surfaces. I guess any layup would include additional layers in 'key' spots.

My question is....All things kept the same, how much heavier would a standard (6oz) layup be then a lightweight (4oz). There is the obvious '2oz per yard' weight gain (about two and a half lbs for 20 yards), how much more epoxy (again, first time builder) will the heavier cloth require...any thoughs on its weight?

Is 3.75 oz cloth concidered 4oz? Raka sells 3.75 not 4.

Is 3.75 on and under the deck, with extra layers behind the cockpit sufficent?
