Double braid ropes are also refferred to as "Marine Ropes","Yacht Braid",or "2 in 1Ropes".They are the most popular and readily available ropes on the market today.These ropes are constructed from an inner hollow braid rope(core)which has another rope braided around its exterior(skin).Both the core and the skin share the load resulting in higher tensile strength than commonly found in twisted ropes of the same size.
