You can buy a 3/8" mid tech line like MLX Samson or Novabraid Argus and strip (taper) the cover to Match the wire rope length of the original. A 3/8" blended core line will out perform the Dacron halyard with regards to strength and stretch and the narrow core will work in your wire sheave as long as the sheave isn't completely chewed up by worn out wire. The cost of Splicing wire to rope will offset the cost of the more expensive rope. And the entire halyard will weigh half as much and reducing weight aloft is always a good thing for racing or cruising. Chuck Gilchrest S/V Half Magic 1983 35 Landfall Padanaram MA
