: Brad,

: Paul's analogy works well here - as long as we are just talking about
: hydrostatic/hydrodynamic loading. If we introduce localized loading, like
: stepping into the boat while on-the-hard, or banging into stuff, the
: stress state can quickly change to a case more glass on the outside would
: be better. But since you don't feel sacrificial layers are important on
: the outside, we could ignore those types of localized loadings. In that
: case, the only extra glass that I might add is a patch inside each cockpit
: where the distributed local load from the paddler's seat causes bending,
: and associated compression on the inside.

Hi, all-I'm getting ready to build my first stripper and need some input regarding glass layup. Ain't getting any younger, as the back and joints occasionally remind me, so light weight is a major consideration, but would like the boat to be sturdy. I'll be using 3/16" strips, northern white cedar; my question is: assuming an efficient use of resin, should I use one layer of 6 oz. glass, or two layers of 4 oz. glass (inside and out)? How do the two compare regarding weight, strength and abrasion resistance? Thanks in advance, Greg
