II++ The Rope that made BlueWater famous.
BlueWater have advanced rope technology another step. Both the double twist cabled core and the double twist, cabled sheath of BlueWater static ropes have been changed and improved. Hence the name "plus plus".
The core remains 100% Polyamide (Nylon) but is now made from a higher performance blend than before. The sheath is now made from a dot-dyed polyester, which has less elongation the polyamide previously used. BlueWater II++ has very low stretch at working loads but retains excellent energy absorption.
