On my 16 foot daysailor I have a Ronstan RF76 furler that uses a drum on the bow-chainplate and a spinning shackle on the halyard. The jib has a luff wire in it.
For a small daysailor it does a good job in several respects. It lives inside the forestay, but can get wrapped. 1. When the jib is unfurled, the sail shape is good. I have to keep a lot of tension on the jib halyard, but it takes all the sag out of the luff wire. 2. The sail furls pretty smoothly most of the time. Occasionally, the jib will bunch or wrap around the forestay if I'm not careful about keeping tension on the sheets when furling.
It's pretty useless for shortening sail. But I've only got a 100% jib, so I usually don't reef with the furler. On occasion, I have furled it down to the size of a "trisail" or stay sail, just to keep a little weather helm. It's fine for that.
I can't speak from experience for a larger boat, especially if you have a 135 of 150 genoa. But for my little boat, I find it extremely useful.
The Harken unit info says not to reef with it as it puts too much load on the overall system.....not quite sure about the physics....one would think with less sail surface the loads would be reduced.......I sail on a lake and will likely never have need to reef anyway.....in July and August we barely have wind, never mind a good blow. The harken is about 1/3 the price of a 'standard' system.....attractive but performance will be the determining factor.
