Larry,
Rig Rite sells a masthead unit that bolts on your masthead. You attach a block to that and run a spinnaker halyard external to the mast and forward of the forestay so it clears the furler and you can hoist the sail all the way up. I added it to my boat and I can't really see how to use that sail without this modification. You also need a way to connect the tack of the sail at the bow. Since the sail is so large I made a couple lines, one for each side, that I tie to my stern cleat and attach blocks to run the sheets through then the sheets come back to my primary headsail winches. This set up worked great and was inexpensive. The sail is great up to about 10 knots of wind. I don't have a sock and have to pull it in by hand so in any stronger winds that is a very tough job.
