All I really care about is if people think the class should allow the sails. The cost is the cost. Since we do not have a large OD class, the cost is going to vary from sailmaker to sailmaker and region to region so I am not sure of the benefit of posting all the different cost. A dacron from one sail loft could be the same cost as a carbon from another - it just depends on so many factors ....

I think there other compelling reasons to allow non-woven mains vs the cost benefit argument.
