Hi Everyone,

I have been away from this web site for awhile. Well, I am back! I own Private Dancer, a Catalina 25 standard rig swing keel.

I launched my boat at Richmond CA a couple of days ago. I replaced my masthead recently. Yesterday I sailed it looking for any problems. It seems as though the jib halyard has difficulty raising or lowering the jib. I think the halyard slipped off of the sheaves. So I am now making plans to get a friend to help me lower the mast to check it out.

I don't remember having this problem before I replaced the masthead. Did I forget to install something that keeps the halyard from slip off of the sheave? I there a way to fix this without lowering the mast?

Thanks for any suggestions,
Char Foster

To your last question, probably not (unless there's a dock-monkey available). My mast-head had an aluminum plate between the two pairs of sheaves, The thickness of the plate and width of the sheaves pretty well filled up the width of the space in the casting, so there was essentially no place for the a halyard to escape to. I also changed to all-rope halyards with corresponding sheaves specifically for the 5/16" rope. IMHO, that's a worthwhile change if you haven't done it, and probably reduces the ability of a halyard to jump the sheaves. (It never happened to me.)

Did you replace the sheaves as well as the casting? If so, make sure the sheaves are of adequate diameter to keep the halyard from chafing on the metal. When I replaced my sheaves for all-rope, I had to order them from a guy on Long Island who made them for me--now Catalina Direct has (apparently) the right size.

I've had my foredeck crew go to the masthead 3 times in the last 3 months to put a halyard back on its sheave.
Last time up there he replaced the sheaves!
It's so much easier (and much quicker) than lowering the mast.

Derek, Of course its easier and faster with a fordeck crew but most of us aren't as lucky to have one like you!

Did you put an ad in the paper: "Foredeck crew wanted. Primary responsibility will be going up and down the mast, but only once a month."

No Steve, his prime responsibility is fast setting or jibing of a 16' whisker pole!

When I went to install my ball bearing sheaves - I discovered they were about half the width of the stock ones. Asked CD "Whassup with that?" and they explained I need to install a set of non ball bearing sheaves to take up the space AND add the masthead divider plate.

Are your halyards all rope or wire and rope?

Mine are wire and rope.

I will compare the old parts to the new after lowering the mast. The all rope setup is interesting. How long is a halyard rope, about 50'?

One of the first improvements I made on Cerberus was replacing the masthead sheaves and replacing the old wire and rope halyards to all rope. It's something worth considering while you have the mast down. Catalina direct has kits with everything you need.

How long the halyard is depends on where you want to run it. The mast is 30' so you need to figure on at least 60' of line if you are just going to cleat the halyard off at the mast. I have my halyards run through deck organizers and rope clutches back to the cockpit. I think I did it with 75' or 80' of line.

Thanks.

West Marine's kits look more expensive than Catalina Direct. What do you think of the Krypton Spectra core line, sounds great!

I got a CD "kit" for leading the halyards to the cockpit, with the Krypton halyards, deck organizers, mast base plate, swivel blocks, and clutches. I would substantially tension my jib furler with the halyard at the beginning of the season to keep the drum aligned at the bottom, and the Krypton wouldn't stretch even a fraction of an inch over the entire season.

CD will customize the kit with the components you need, and omit the ones you don't. The prices are competitive with WM--you could probably do a little better with Defender or others, but they don't know the details of our boats (sheaves, etc.) and certainly don't have the mast base plate.

My 79 TR had 4 thin sheaves at the top for my rope and wire internal halyards. While sending someone up the mast to fix my windex the black plastic sheaves cracked. We took the divider plates out and replaced them with 2 wide white plastic sheaves that were originally designed for a C-22. They fit perfectly, we just had to drill out the center hole to accommodate the width of the bolt. I also reduced the amount of halyards I have as I have roller furling now.Works pretty well so far and no room for the halyard to slip out of groove.

I bought the Catalina Direct halyard rope kit, lowered the mast, replaced the sheaves and halyards and stepped the mast. After going sailing, I must say I am very happy with the upgrade. The jib and main has never gone up or down so easily! No more 'fishhooks' that my old wire halyard had that would draw blood on a semi-regular basis.

Thanks for everyone's comments and input. I used what many fellow sails said in order to come to my final decision; which I think was the best decision. Thanks!

For the line - I have now replaced 2 halyards. I would not spend the extra for high tech line. The store would love to sell it to you, but reality says that even if you get super line with tapered ends and have a lazer guided winchhandle, you are still putting it on a boat that won't appreciably change with the improvements. Basically you will spend the money but not see any great gain over a less costly line. I would put the money away for higher-impact improvements.

Got to your local chandlery, look at the spools, tell the guy at the desk what you want, and compare that price to what saw online. These are the sorts of things I would rather buy locally, but thats just me.

For Iris we got 75 feet for the jib halyard and for the whisker pole topping lift. There is a little stretch in the whisker pole line, but not enough to worry about.
