Hi everyone,

I was just climbing around on my boat and I noticed this broken thing in the top of my mast:

<img src="http://im1.shutterfly.com/procserv/47b2cf32b3127cce91bb3ac5380e0000001410" border=0>

What is it? What does it do? Do I need to worry about it? So far I haven't had any trouble raising the main or the jib, but I'm sure it oughta' be replaced sooner or later ... I'm hoping later.

Thanks for the help!

To me, it looks like a thing to keep the different halyards sepate at the top of the mast - but that is purely a wild guess.

It'll be interesting to see what others think about it.<img src=icon_smile.gif border=0 align=middle>

Good guess. I too, think it's the separator plate that prevents the halyards from crossing each other or allowing them to jump off the sheaves.

Yes. It is a separator plate that runs between the sheeves. its purpose is to keep the sheeves separated and steady so they don't float around. It may also contribute to keeping the halyard wires from jumping off the sheeves. You might be able to raise and lower the halyards, but at some point they are going to jam or you will cause wear on parts. If you have ever run into Murphy you know when this will happen. It's an easy fix (once the mast is down or you are up it). Do it.

I think I paid $11.00 for a sheave divider when I ordered replacement sheaves from CD. You could easily make a new one.

"If you have ever run into Murphy you know when this will happen"
Sure do! It happened to us this weekend - went to raise the main on the race course and it jammed 1/2 way up...wouldn't go up nor come down. Had to persuade a friend (on a nearby J22) to climb the mast and release it. The replacement sheaves arrived this afternoon...

Buzz,

I'm pretty sure I have a suplus one since I converted to internal rope halyards a couple years ago. If you want it, I'll send it to you.

Hi Eric,

That would be GREAT! I will send you an email with my address as soon as I finish this post ... if you don't receive my email, please let me know.

Thanks a lot!

Hi Buzz,

As others have already posted, the broken piece is the seperator plate between your halyard sheaves. Catalina Yachts calls the seperator an aluminum spacer. It can be seen on page 14 of the parts catalog (located in the brochures part of this website).

While you are replacing the spacer, take a close look at your halyard sheaves. Those guys sit up in the sun day after day and the plastic becomes brittle after a while. The lip on the sheave will start cracking and breaking off. You will surely have a halyard slide off the halyard at the worst possible time. So, consider replacing the sheaves too...........

Hey Buzz,
I know all those parts well. I just converted my cable halyards to all rope. I had to order new sheaves to accommodate but that baby is definitely your spacer and if its broke, you want to replace it.

The thing that I've found strange is that only one end has a bolt through it. The other side just sits in place. I guess its a gravity thing.

Does that Murphy guy sail with all of us? He's like a bad first mate. He's always there when I don't need him!
