Spinnaker halyard

Hi everyone, i'm a new owner since last july of a C&C 27 MV 1985. Since last fall, i'd do lots of work inside and out the the boat to fix few problems and do upgrades. I'm now, on my check list, on the spinnaker affair.
The boat came with a spinnaker ang gears, but without halyard !. I presume the previous owner use the second genoa halyard to lift the spinnaker ( i have a 2 track Harken furler ). I use this 2nd halyard a couple of time, but as this halyard is below the forestay, it's not a perfect rig don't you.
Is someone can tell me the configuration on the top of the mast ( i have a Cinkel mast ), or have a link for pics or so ?
Thanks,

Re: Spinnaker halyard

Hello Jean, welcome to the Mark V fleet. I have hull #75 and sail out of Toronto. The Mark V mast was designed to accommodate 2 Spinnaker Halyards They run over an internal sheave built into the top of the mast. Replacement sheaves can be purchased from South Shore Yachts. If you go to main page of the web site and click on Sea of Change MkV then scroll down that page to Mast and Rigging you will pull up a page with the rigging diagram, in the right hand illustration at the top of the mast you will see a triangular protrusion on the top of the mast that is the Spinnaker halyards entrance box. With your mast down you will be able to remove 2 screws and remove the box, this is how you access all of your halyards sheaves, if the plastic sheaves are in good shape your good to go to run the halyards in. you will need another person and an electricians fish tape and a good flash light to run a tracer line down the inside of the mast. Be careful when pushing the fish wire down the mast that you don't foul or wrap it around any other halyards or wires. One way is to make sure all of the other lines inside the mast are a taught as possible.
Good luck and good sailing

Re: Spinnaker halyard

Thanks for reply Steve,
I already remove the top plate of the mast as the mast is down for winter, but i have no sheaves left for addition of the spinnaker halyard. I will able to find one or do one if not, here in Montreal area.
I saw the drawing in the sea of change section, but they was not very explicite to the details of the sheaves. The profile in center of the mast is already groove to receive a pin to stand the sheaves, but should have a second sheave i guess near the exit to avoid rope wear on the aluminium profile.
Anyway i will take a close look on that in the next days to find a solution. Maybe instead of a second sheave, a piece of Teflon will do the job and protect the rope...

Re: Spinnaker halyard

Jean:
There is only one sheave for each halyard, it's a small (approx. 3/4 - 1" dia.) nylon roller, it's purpose is to  provide a low friction fairlead as the halyard runs down the inside of the mast. The halyard enters the mast (at the top) through an aluminum casting, the edges of that casting are smooth so that the line won't chafe, there is no provision for any rollers as the line enters the casting. If the nylon rollers are worn and need to be replaced you can order them through South Shore Yachts, the people there are very knowledgeable about all models of C&C's, it's well worth a call, you can find their phone # in the contacts section of the home page of this web site.

Re: Spinnaker halyard

Hi.  I have a 1987 Mk V which sounds like it is set up similar to yours.  The mast is down for the winter, and I would be happy to send photos of the mast head for you to have a look at once the snow is gone.

With respect, I would not think running the halyard over the shaft without a sheave would be a good plan - the friction would be very high, and together with the small diameter of the shaft this would create a very high load in that area putting terrific strain on the line and risking breaking and damage.

Re: Spinnaker halyard

Thanks for Steve,
So only one sheave and the exit is enough smooth for the rope. Sounds good.

Thanks for Barry,
With the comments of all of you, i can manage to fix my halyard properly, but of course, pics will be appreciate as well in the Black Arts.
Just love this site,

Thanks again,
