Low Aspect High Modulus Sailcloth—lowest bias stretch, highest fill count and more even crimp. The result is an excellent sailcloth with a reasonable price. Use High Modulus Low Aspect Dacron in sails with an aspect ratio of 2.5 or less (luff/foot ≤ 2.5).
An excellent choice for those who are racing older boats with relatively long "E" and "J" measurements. This cloth is designed to reduce bias stretch to a minimum. It has a medium hand.
