: THE FABRIC: 1. 6 oz. plain weave left over from Pygmy kit.
: 2. 3.25 oz satin, 2 layers thick, from Raka.
: 3. 5 oz. satin from Raka.
: 4. 8.9 oz. satin from a local source.
: 5. 3.75 oz. plain weave s-2 glass, 2 layers thick, from Raka.
: 6. 6 oz. satin s-2 glass from John R Sweet.

I presume that the samples with two layers of cloth were layed-up
with the yarns parallel ? Do you think there would be any benefit
in having the yarns at 45 degrees to each other ? That might be
difficult to achieve on a boat, depending on the width of the cloth,
but having the length of the cloth aligned 22.5 degrees to the boat
centre line, one layer having that angle to the left, the other to
the right might achieve a more uniformly strong composite, even if
it wasn't actually any stronger in its strongest direction. Want to
do more tests, or is the single layer 6 oz s-2 glass so much superior
that it isn't worth knowing about anything else ?
