I have a 36MKII tall rig with std. set up for two jib halyards. I haven't been to the top of my mast yet, but it appears the two halyard pulleys are right next to each other. I plan to fly and asym spinnaker and gybe the sail around the front of the furled jib. I'm concerned that if I use the extra jib halyard I already have, it may cause chaffing between the spinn halyard and the furled jib since they are right next to each other and the spinn sail/halyard will rub on top of the furled jib depending on course. I read in the recent MAINSHEET Catalina 400 segment that it is recommended to add a separate block at the top of the masthead. Not sure if this was attached to std. masthead or if a special extension plate was added?
Anyone have a detailed sketch or drawing of the std. masthead and asttachment points for a C36MKII tall rig? I couldn't find one in my manual.
Anyone have experience flying an asym spinnaker using the second/extra jib halyard? Any problems or chaffing? Did you gybe the asym spinn behind or in front of the furled jib sail?
Anyone have experience adding an additional block for a spinnaker halyard on the masthead? Did it require additional extension or plate to attach the block? Where you able to run halyard down through mast to avoid halyard slap, etc., or was halyard run outside of mast?
Thanks for any help...................

This is the masthead on my older short rig boat but the principle is the same.
The block out in front of the forestay is for the spin halyard. The halyard on my boat goes into the mast about 3' down from the top, but it could be rigged externally too.
The trick is to do all this without having it foul the top swivel of your furler, which mine did when this pic was taken. Among other things the hoop that this spinnaker block is mounted on should be offset as for to one side as you can so that the tail of the spin halyard doesn't drag across the forestay or the swivel.

You DO NOT want to use the spare jib halyard for the spinnaker.
As posted above, a swivel block on the masthead bail is the way to go. I ran my spin halyard down through the mast ports and added a cleat on the port side.
For gybing, you can either douse the spinnaker with a sock, then move it to the other side and redeploy it. Or, you can use extra long sheets like I do and let it fly in front of the forestay as you gybe.
I hope you enjoy flying your spinnaker as much as we do.

Jason (or anyone else) -
Having just picked up a used assym for our boat from a former C36 owner, we need to add the running rigging to fly it. Your photo was helpful. Do you recall the specs of the block at the masthead you have in your photo (make, model) (or, suggestions as to its capacity)? And, how do you "offset" the block to one side, as you suggest?
Thanks

Matthew,
A Garhauer Series 40 swivel block works perfectly. Also, I think that the spinnaker halyard exit box in the mast is 2-3' below the masthead on the Stbd side of the mast, and not on the port side. The lower exit box is 6-7' above the deck, also on the stbd side of the mast. If you use those exit boxes for an internal halyard, and you pull the spin halyard back to the shrouds on the stbd side when not in use, I found that I never had a problem with the spin halyard rubbing or tangling with the genoa furler upper swivel. If you "split sides", i.e. have the spin halyard come out of the exit box on the stbd side, and have the spin halyard tied off on the port side, I would sometimes have problems with the spin halyard getting messed up with the genoa furler swivel. Just a thought.

Definitely on the left side on my '83 boat. The block at the top is a Schaeffer block, don't know the specs on it but same size as the larger ones in my mainsheet system. I'd think even the Garhauer 30 series would do the job.
To offset to one side, you will see other brands of boats where the whole bail is bolted on to the masthead at 45 degrees. This is not easy to do with the boat sitting. What I have done is to attach a cheek block to the side of the mast above the cap shroud termination - this routes the halyard from the flying block already discussed, back to the cheek block above the whole furler issue, then down cleanly into the exit hole on the mast.
Tom's method will probably work if you are just cruising as you can furl the jib before rigging up the kite. I race and need to be able to hoist the spinnaker BEFORE I furl. Frankly getting the kite down and tamed is a lot easier if you can unfurl first also.

In this pic you can see the halyard setup. It runs from the mast up to the cheek block on the side of the rig, then forward at an upwards angle to the hanging block, and then the tail runs back down and is led aft outside the shroud to keep it off the furler.

Thanks so much, Tom and Jason!

As stated; mount the block on the masthead 'bail' or 'crane' and if possible run through the starboard entry and exit points. I did this setup last summer and actually had to switch out the topping lift which had been run through part of the starboard side ports...
Set up works great, with no interference with the furling.
