On small boats, I believe those are called wire luft furlers and I use this type of furler on my 15 foot dingy. When I raise the mast on this boat, I pin the fore stay - but the actual tension on the jib is from a wire cable in the leading edge of the jib. The forestay is now pretty much not used (no hank on clips)- except that it is a backup if the wire luft in the jib were to bust.
I don’t have a furler on my 26S.. too much hassle if you raise and lower the mast much (its not the actual raising of the jib furler that is the main hassle - its all the additional stuff you have to do such as wrapping the fulrer on the mast so that you don’t damage it). However, on this small boat it makes the setup a lot easier. The wire luft furler is not at all fragile when the sail is down and I just leave it attached to the boat at the bottom and let it fall into the boat when I lower it. Setup - raise the mast and pin the fore stay, connect the halyard to the top of the jib, raise the jib and set the tension with the halyard. Very fast - less than one minute (it takes me less than 10 minutes to set the whole boat up).
I didn’t care about the ability to "reef" the jib (i.e., partially furl) but what I found is that not being able to reef also meant not being able to furl in high winds - exactly the time when I need it the most.
The boat this on is experimental - (translation I can try any funky or goofy thing I want) so I put sections of PVC pipe run through a table saw to put a lengthwise slot in the PVC over the jib leading edge. There are three sections of PVC pipe that provide "joints" to lower the stress when the sail is raised or lowered. The third picture below shows how far up the jib the PVC sections go (see the arrow). Adding the PVC leading edge now makes the wire luft jib way easier to roll up in high winds. I was somewhat surprised to find that this also allows the jib to be reefed although I really never use this.
I can’t remember the wire luft furler I bought and it works fine.. but I wish I would have spent the extra money and bought the Harken small boat furler just because of the larger drum.
