Hi David,
Just a pointer about fibreglass itself. It is strong in tension. So you need it strong on the inside. The football on the outside is mainly for wear and tear. If you sit on the deck you need the strength on the inside. When you hit rocks you also need it on the inside to stop breakage. So wherever you see potential deformation, you need the strength on the side that has to stretch.

: Hello All,
: I am about to order fiberglass for my Outer Island and I have a few questions
: maybe someone can help me with.
: 1) Can I get away with ordering 6 and 4 oz in just the 38" width? Will
: it be wide enough when the 'glass is laid on the hull on the bias?
: 2) In the instructions that came with the plans, it said to put the football
: and stem pieces under the outer layer, while this method seems to be a
: little less work and less mess, does it leave an outline that shows
: through the outer layer and if so will fill coats and a little sanding
: clear that up?
: 3) Has anyone done this with 4 oz under the 6 oz outer layer? Is there much
: durability that I sacrificing over weight savings?
: 4) With the standard 6 oz outer layup on the outside, can I get by with 4 oz
: on the inside of the hull?
: 5) can I use 4 oz on the inside and outside of the deck?
: I am using 3/16" strips and its alot thinner than that in some areas,
: like probably 1/8" so I want to avoid as much oil canning as
: possible. The boat will see some action on the rocky shores of Lake
: Superior.
: Thanks,
: Dave
