The minuses are that it is too thin to get a grip on, you can't clearly see crossed lines at the top of the mast and it has meathooks that tear sails and your hands. On top of all that it requires rope to wire splices that you will almost certainly have to pay for since few owners can do them.What are the minuses to wire running rigging? What do you gain by changing it out?
Same here. Same boat. Replaced aging main and jib wire/rope halyards with VPC. Several years now, no regrets.Just replaced the wire/line main halyard on my Cal 33 with all line. Went with New England VPC which is a "mid tech" line. The cover on the old halyard was in bad shape in several spots, so it was time. Never considered staying with wire/line.
Then you need to take a look at modern lines.Stumble. Are you saying wire stretches more than the typical line one might use for a cruising boat halyard? I find that hard to accept.
I would also question line having a weight advantage, and there is no question wire has the windage advantage.
Just mark me down as one who is fully satisfied with my old wire/rope halyards.
