Chris,
I am finishing a GE right now. Seaming it as we speak. I would recommend using the glassing schedule of:
4 oz on the top
4 oz on both interiors (hull and deck)
6 on the hull bottom only
I got 37 inch width. And it worked fine. The extra turns into bias. Go a little over the length of the boat on each swath. I went 3 feet over length. As it forms over the
curve you need a bit extra and what is left will get used in other places. (bias)
If I read you right, You are thinking about about using 6 oz only. After doing a similar schedule, I would suggest against it.
Using 4 rather then 6 will cut a good deal of weight out of your final project weight. More then you might think. However, more importantly, it will make mating the
seams a whole lot easier.
From the lessons learned file: I use a boat hard, (I like playing in the shoals and get my share of surf landings) So I decided to trade up on weight for a little extra
strength. Good thinking but life is in the details.
Thus, Against sage advise, {You can always tell a Norwegian you just can't tell them very much } I did 4 top/6&6/6bottom and a set of ribs under some fancy
work that needed a bit more support. Result: I have been having some trouble seaming the boat. I have had to resort to load tie downs in some places to pull it to
trim. Its going to come out righteous, but it surely is not something I will do again. If I had gone with the suggested 4 inside and the set of ribs I would have had a
much easier time pulling her back together.
I would suggest going with the 4 oz on 3 surfaces and leave the 6 oz for the bottom. If you use a boat really!! hard, and want a little extra strength put an extra
swatch of 6 oz under your seat and keel, but my lesson learned is keep those second layers well away from the seams and sides so she can flex a bit more.
The good news out of this trouble is, I have found a new technique I like, and I am going to continue to employ in other boats. I like the flexibility that the strap
webbing gives me in pulling a boat together. I find Its easier and gives me more control then taping. I'll post something on the technique later. However, I don't want
to have to horse a seam as hard as I have had to again. Its not a project killer, but its not worth doing twice.
As for tape: I'll pass along Michael Vermouth's suggestion buy the tape for the inside seam and cut 4 oz bias for the outside seams. Tape has a hard edge that rises a
bit as it is impregnated. Thus, requires a lot of sanding to feather the outside edges to invisible. So its best used where its not seen.
I am using 4 oz scrap to cut bias for the out side and the 6 oz tape inside.
Its proving to be very strong combination.
Good luck and by the way....... I think GE will make a perfect cradle,
