Striclty speaking there are two types of headsail storage systems, furling and reefing, and as far as I know only two on the market are true reefing systems. By this I mean they keep an efficient shape when partially furled, non of those ugly creases at 45deg.
They do this in two ways. Firstly by having not only a head swivel but also a tack swivel, and secondly by having a 'set back' cut into the head and tack of the sail. As the furling line is pulled and the foil turned the head and tack are left behind slightly, flattening the sail as it is furled.
Furlex is one of these and they are a nice unit but have a plastic drum surround which I'm not a fan of.
The other is these guys www.almasts.com.au
The guy who designed the Reefit still makes it and I'm sure they can ship anywhere.
I have sailed on many boats with these furlers and they work really well. Also Ken Gourlay, the man who is the oldest and fastest Aussie to sail around the world non-stop, used one of these without a hitch all the way round.
I have sold all types of furlers for a few years and it's by far and away the best on the market in my opinion. That said I don't sell many Harkens or know much about them as they are very expensive here in Oz and Harken's after sales service here sucks!!!
Plan to get some shots of the sails reefed next time I'm out on a boat with a Reefit, so if you want them PM me.
