If you want the best furler made, consider the Reefrite system from NZ. It is very well engineered, and uses "Kiwi slides" instead of a boltrope to attatch the sail to the foil. This makes sail changes easy, and quick. I sail a 35ft cutter equiped with this system, and have been in some very heavy weather where it was necessary to change headsails, this was no problem! I have hanks on my inner forestay for my staysail and storm jib. The furler also has a ratched system, (like a sheet winch), controlled by a small cable and a highfield lever. This means that the sail cannot unfurl accidently.
