I'm about to replace the spin and jib halyards on my boat, and I'm wondering what the sheaves are like on a 1982 model. The halyards that are currently there are what looks like 1/8" wire spliced to 3/8" line. I was originally planning to just use 1/4" line all the way through as replacement halyards, but I'm concerned that they may be too wide for the sheaves, given that what is on there (likely orig equip?) was made for much narrower material passing through it. Anyone have any experience replacing halyards on these boats?
