OK I lowered the mast earlier this year and put on new sheave blocks with bearings in the mast head. all external cables. I just used the same ones. could have possible switched sides.

The new jib and furler worked great. However when I went to raise the main I pulled the halyard on the mast winch. This year the wire reached the winch and the main was still 4-6 inchs low. Needed to go up 4 more inches.
There were two wire halyards, the Jib and the Main. are they the same size. How high is the boom off the deck. I dont think this is the issue because I can see the main is not high enough with the wire pulled down as far as I could. Any thoughts or suggestions?

Also I dont think that the last 6 inches would go if I pulled harder It was hard to pull when halyard when from line to wire. I will be contemplating replacing the wire next year.

That happened to me a long time ago and my memory is a little hazy about the details, but, as I recall, the wire parts of the jib halyard and main halyard are different lengths. When I replaced the sheaves and wire halyards on my C25 tall rig, I apparently switched them and had the same result. I had to take the mast down and switch them back and the problem was corrected.

This is a good reason to convert to all rope halyards.

If you have the mast step plate, you could add a block there, run the rope part of the halyard through that, and back up to the winch, at least until you can drop the mast again and swap them back. Next time you do halyard maintenance, consider changing to all rope halyards (may require wider sheaves). You won't regret it.

Hi, I am about to replace the main halyard on our C25. I bought the bearinged shives from CD.I suppose i will need to step the mast in order to replace the halyard...I want to get rid of the old wire halyard. Catalina said the main should be 82 feet? I am pretty sure we have a standard mast. I cannot find any images of the shives or clevis arrangement before I do this.

Any Ideas?

Internal or external halyards? With external, there are two clevis pins in the mast-head, with two sheaves on each and an aluminum plate between them to keep halyards from crossing over or getting jammed off the side of a sheave. Internal halyards run on a single wider sheave on each of the two pins--one for each halyard.

The new sheaves you bought probably shouldn't be used with the wire halyards--what CD sells now, to my knowledge, is designed for all-rope (5/16")--the smaller wire under tension might not be good for them.
