Mike: if you like the length just duplicate. if want a little longer add a few few. always better a bit long the too short! ;-) the mast, if to Jerry's spec, is 19'2" including masthead fitting. you can use this as a method to measure your current halyard. 1/4" double braid is fine. now, if the wire to rope is in good condition i would recommend keeping ... less stretch that results in better main sail shape (the luff doesn't elongate as much causing the sail to bag). a wire-to-rope jib halyard really helps keep a headsail from bagging at the luff. the masthead sheaves, if the correct ones for wire (meaning the wire didn't damage them), are fine for 'rope'. -- :: Dave Scobie :: former M15 owner - www.freewebs.com/m15-named-scred :: M17 #375 SWEET PEA - www.m17-375.webs.com On Wed, Feb 10, 2016 at 9:27 AM, mrh219--- via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:
I know this question has been asked before, and apologize for the repetition. I am thinking of replacing the wire/line main halyard with an all rope line on my 2007 m-15. What is recommendation for line, size and length? Will the sheave at the top of the mast need to be modified? Mike Hettlerm-15 anne bonny
