rubbing spinnaker halyard

[berwick]

Hi, on my fairly new to me Tartan 37C I added a pulley and halyard for a spinnaker which attaches to the a 10" tang which goes horizontally out from the top of the mast. The problem I have now is that when the top part of the Harken foil turns (when furling) it rubs and can catch on the spinnaker halyards as the Harken unit is fairly large in diameter. There is a small pennant (12") on the top of the sail to keep the top part of the furler unit near sheeve to get the angle right to prevent the halyard wrap (I think).
So what options do I have to fix this besides taking the pennant off to lower the unit a bit and then I have to add some sort of halyard diverter to the mast. Right now I run the spinnaker halyards behind the upper side stays and this works but I worry about cafe and would like to do it properly.

Thanks in advance,
Richard

Hello,
This is one of those cases of overlapping technologies, with your spinnaker halyard gear. meeting up with something it wasn't designed to deal with: the jib furler. The best way out is to mount a somewhat long crane, with the end offset to one side, so the block, and thus the halyard, do not so easily come in contact with the swivel. You'll still need to keep the line off to one side, but it will be easier.
Is your current crane short? Does it lead directly forward from the mast centerline? If either one is true, that is the problem.
You are right about the swivel being where it belongs, to prevent halyard wrap. It also put the swivel over the bearings, for less foil deflection. So don't lower that.
Fair leads,
