If it is a CDI Flex Furler, then yes, you will have to unpin the headstay and unscrew the turnbuckle to remove the drum and foil. The good news is it's easy enough to do, although the foil is rather heavy. If you change your mind and want to re-install the furler, you will have to drop the mast. I don't think it's possible to put a Flex Furler foil back up with the mast up due to the weight.
