Mooring Line. 3/4" Premium 3 strand nylon. Heavy Duty 316 Stainless Steel Thimbles and Stainless Steel Bullnose Snap for Bow Eye. 
One of the most important building blocks of any mooring line is the fiber. We utilize U.S. manufacturers for our “PREMIUM LINE” three strand nylon, spun from domestic fibers and of four-stage balanced construction, a stabilization process treatment with a proprietary “Marine Tech” coating to improve wet strength and enhance fiber to fiber abrasion resistance. 
The four-stage process involves steaming to heat and preshrink the fibers during the spinning of the different size yarns that graduate into the finished product. This helps to minimize shrinkage and hardening of the rope and will inherently provide high strength with stretch for shock absorption and resistance to UV Rays.
The finished product is identified with colored tracers unique to the rope manufacturer and in accordance with their stringent quality control specifications. The splicing process for the mooring lines involves a five tuck, flat lay assembly over hot-dipped galvanized or stainless-steel thimbles and is heat sealed to prevent unwinding with minimal stress on the splice.
Lines include a stainless-steel bow eye snap for superior corrosion resistance and performance. Hardware options range from stainless steel swivel snaps to various connections appropriate for the application.
