What is the most structural fiber orientation?

When I glassed my North Star I made sure the fibers ran straight down the keel and deck centerline. But I questioned if it would be better to run the fibers at a 45 degree angle to the longtitudinal axis thus providing more torsional strength. It seems there is more strength longtitudinally inherent to the design. I am not an engineer though. Maybe two layers of glass, one at a 45 degree angle to the other?

I am starting to strip a Guillemot Expedition.
