Am presently converting to all line halyards. The sheaves that CD sends appear to be Schaefer 1-3/4". The halyards come awfull close to where the masthead meets the mast. Due to being limited by the width of the sheave, larger sheaves like the 1-7/8" are too thick to fit two sheaves and the alum plate separating them. Any thoughts. Barry.

One option that really opens things up is to convert to internal rope halyards. You then only have one sheave per halyard rather than two. One aft for the main and one forward for the headsail. I know some people Dremel out some material at the mast head when putting in new sheaves.

Please ask more question, we are here to help.

Belpat marine makes replacement masthead sheaves the 'right size'... The ones I got from CD are still in the rigging box. If you search on 'Belpat' the phone number will probably turn up.

Likely. IMHO 3/8" line is pretty heavy for halyards on a boat the size of a C25. I think most of us probably use 5/16" sta-set X (or equivalent)... the racing-oriented folks like 1/4" high-tech line.

I bought the all rope external halyard kit from CD. The sheaves are insalled in the masthead, however the mast is still down. Hope to get everything up and going next week. Am I understanding here that several of you have had problems with that arrangement? I'm only using it on the main as I have a roller furler.
