A method for construction of a large diameter braided rope. The rope is formed of high strength, low elongation synthetic fibers which are twisted together at a twist factor in the range from about 125 to about 145 to form a plurality of comparatively small diameter yarns. The small diameter twisted yarns are then braided together at a pick multiplier in the range from about 1.0 to about 2.0 so as to form a plurality of braided strands, and the strands, in turn, are braided together with a pick multiplier of about 2.0-3.6 so as to form the large diameter braided rope. The braiding of the strands imparts a degree of coherence which permits a lower twist factor to be used in the yarns. This results in a significant increase in translational efficiency over conventional twisted-strand construction, by avoiding the over twisting of low elongation fibers which occurs when forming large diameter yarns.
