New England Ropes’ “Viper” line of lightweight cordage provides a combination of exceptional strength and flexibility, in the process providing better performance than an all-polyester without the premium price of more exotic high-tech line. At the heart of the line is a low-stretch HMPE core that is UV resistant and also surrounded by a braided polyester outer jacket that can be easily stripped off for even greater weight savings when being used as, say, a spinnaker sheet. An assortment of different colors are available, including redfleck, bluefleck and gray and black. Tensile, or breaking, strength for the 8mm-diameter line is an impressive 7,000lb. Tensile strength for the 12mm is 16,000lb.
