CDI
I had a CDI roller furling on my Catalina 30, it was there from the previous owner. It was a bit small for the Catalina 30, but did work. I would advise against it on a 30. but it would be more than adequate on a 25 footer. RF are great in bad weather and as far as i'm concerned, they are the only way to go if you single hand in open water. Anytime you dont have to go up forward, its a plus. More than once I was caught in unpredicted bad weather and had to go forward, alone, with no autopilot and change sails. You cant always see high winds coming, and yes, i know all about looking for 'signs', but life is different when single handing. Even when 2 on a boat, if really windy and having a great time with the rail in the water, tacking becomes easy if you furl a little before the tack.In addition to making your life easier, think of it as a piece of safety gear. Oh yes, some will say that roller furling can get jammed. Yes, i agree, but that is rare. If it does, just be prepared to slash your jib to ribbons if you have to. But keep in mind, you are MUCH MUCH more likely to be pitched off the bow of your boat tring to reduce sail than you are of having your RF jam. Oh yeah, i forgot, everyone wears a safety harness. Sure, now you can pull down a large jenny, fold it anyway you can and tuck it inside the boat in 35 MPH wind on a 25 footer and all this while safely tethered. yeah, right.
