New question..... Triradial vs. Horizontal-cut dacron sails.
What is the difference? Why do I want one or the other. Why does Triradial cut cost a lot more? $820 vs $ 975 from Calvert for a 5.0 oz Yellow Square-Top Dacron Main.
Thanks
Greg
Triradial is better because it aligns the fibers in the direction of stress on the sail. Thus the sail is consistently stretched throughout.
Triradial costs more because you waste more material when building the sail because of the many cuts.
