Is there a diagram available as to how the halyards are run? I have the mast down and ready to run new lines but I don't know if the current configuration is correct. The main and jib halyard is easy to figure out but after that I need help.

On the forward side of the mast are two sheave boxes. The lower one is just above the spreaders and has two sheaves in line and currently the Spin halyard is run between these two sheaves as it exits the mast and continues up through a block at the top of the mast. The stamp on this box is FICO Australia FG 943 and I will need to replace the sheaves if anyone has tips for this as well.

The other box is a single sheave about 2' from the top and there is not a line run through this sheave. I don't know if this was for the spin pole topping lift because it looks like the halyard line coming out of the mast and continuing up would rub on the line coming out of the single sheave.

There is another unused block attached at the top that I don't know what it was for either.

Any ideas? Any one have a diagram as to how the lines should be run?

My guess is that someone rigged your boat to have the spin halyard exit at the spreaders and run to the mast top block. I don't know if that is correct or not, but on my boat when I got it, it had the spin topping lift exiting from the sheaves at the spreaders and the spin halyard exiting at the top of the mast. There is a drawing on this website titled "Control Arrangement @ Cabin Top" that identifies the lines going INTO the mast base, but I've never seen any diagram of the lines as they exit. I've just been going by the way I received my boat for now. That's all I'm sure of, someone else will probably have a more definitive answer for you.

Not sure if you know this but there are actually two jib/genoa halyards. One on the port side and one for the starboard side. My spinnaker halyard comes out of the top. I'll be doing some work this Friday on Kami and I can take a close up pictures if you need them.

Thanks for the response. Pictures would be great. I have some pictures but don't know how to post them on here.

I went back out to the boat last night and I see that my original post was not completly correct. There are two sheave boxes in the mast with two sheaves stacked in line. The one at the spreaders has the topping lift going between the two sheaves. I need to replace the sheaves on this one but not sure why I would need to replace it with the two in line sheaves.

The sheave box where the spin Halyard exits is about two feet from the mast head and the unused single sheave is about 1' from the mast head.

The Mast head has two sheaves for Jib Halyards and two sheaves for the main. I am going to drill out the rivets on the boxes and hope I can replace the sheaves and reinstall.

Spin halyard has to come out at the masthead otherwise the spin would be fouled by the forestay.

I would like to take credit for this arrangement but, I saw it on another Capri 25 at my YC in FLA.
At top of mast centered on Port side I cut in a 3 1/4x1" Harken exit plate #163857 appx. 10" from mast cap, then a cheek block above, halyard goes thru to a shackle hung from the bail on cap. Be sure to eyeball positions so that halyard does not chafe. Halyard goes out over forestay. When spin. draws, halyard is pulled out ahead of forestay. Exit thru same size plate on Stbd. side of mast appx. 7' off the deck for a good purchase when raising sail then thru a Harken RF5010 cam cleat appx. 1' below plate for quick tie off then finally to a cleat at appx. 3' off deck. Works extremely well for me and has been copied by others who praise
this arrangement. Have fun.
