I just got new ball bearing sheaves (QTY 4) from catalina direct.
I was about to install them when it occured to me to switch over to internal halyards.
I'm hoping someone out there could give me some guidance.
The idea of cutting slots into the bottom end of my mast is a bit worrying.
I don't have a spinnaker, but the idea of having an extra halyard (or two) seems like a good idea.
One other thing, what's the thinnest halyard I could use without getting in trouble. I have 3/8 on there now (no wire) and it is tight pulling the main up.

Welcome to the forum, Scott!

The topic of converting to all rope internal halyards is discussed extensively in a recent thread. ([url="http://www.catalina25-250.org/forum/topic.asp?TOPIC_ID=5694"]Previous internal halyards thread[/url]) You can pick up an extra halyard by attaching a bullet block at the masthead, without having to run internal halyards.

It sounds as though your 3/8" halyards are trying to run through the old original sheaves that were designed for wire. If so, the halyard is likely getting sucked down into the too narrow wire groove and hanging up. New sheaves should fix that problem.

Depending on the type of line, some people have halyards as small as 3/16" (I think I have shoe laces thicker than that! )

I have 5/16" halyards because it was on clearance when I bought them, but if I had to replace them I would probably go with a smaller, lighter, higher tech line.

Scott - I just replaced both jib & main halyards with 3/16" hi-tech line (V-12), with a 5/16" tail. The 5/16" could not be reeved thru' from the deck because the sheave designed for 1/8" wire will only take 3/16" line, so my buddy went up the mast to feed it through - and it was a struggle even then.

My 3/16 V12 line center spliced to 3/8 tail new halyards arrived yesterday. They are very, very light. $270 for a shoebox full of rope! I can't wait to put them on. I am not bothering to change over to internal. These will work externally and run through the existing sheeves.

I'll post some photos.

You may want to invest in a CDI roller furler next. This will free up your jib halyard anfor yse with a cruising spinnaker. I changed my halyards out a couple of years ago and used the wire to rope type from West Marine. They were about 100 bucks each.
