What Joe mentioned, is exactly what I do with my CDI furler. I tie a messenger line to the shortened (cutoff) halyard to drop the sail and use it to raise the headsail and remove it and cleat off the shorten halyard. When we remove the head sail for the season, I use a second messenger line to pull the halyard back down into the furler extrusion so it's protected from the weather for the winter and remove the primary messenger, leaving the second messenger exposed to the weather and tie that off where it's not slapping the mast for the winter. Seems a bit goofy, but it works for me. The good rope is too expensive to leave out all winter.
