The halyard goes through a tracK?
I am having a hard time picturing what you are saying.
My halyard attaches to the top of the upper swivel, the sail head attaches to the swivel, and the luff of the sail is attached to the foil with the bolt rope and runs in the extrusion, but the halyard is not run inside of anything.
