I'm trying to find a replacement halyard line and have seen lots of names like spectra and sprintline but there aren't any local Marine supply stores that carries these. Is there any reason why 5 or 6mm climbing line from a reputable outdoors store wouldn't work? The line is rated for approximately 1500lbs of tensile strength and is supposed to be static and won't stretch, is this strong enough for the Halyard on a sunfish?
Thanks
