I'll say from my research the price difference between a woven poly sail (aka Dacron) and a higher strength laminated fabric is marginal. The bulk of sail cost is now in labor rather than material. I understand the class rules to be preventing arms-races, but for such a slight increase of material cost we could be utilizing better sails.

Perhaps opening the ruling to allow higher tech laminates but stop short of membrane sails. Membranes tend to cost significantly more and have some of the shortest life cycles.

Just a thought.
