Taking down a roller furling jib is generally done the same as taking down a hanked-on jib. You release the jib halliard, and the sail should fall to the deck. You might need to pull it down at the luff, if it doesn't fall all the way by itself.
I'll admit I haven't seen all the types of roller furlers ever manufactured, but I never saw one that didn't use a halliard to raise the jib.
Every factory stock Catalina 25 had two halliards. The halliard on the starboard side of the mast was for the mainsail, and the halliard on the port side of the mast was for the jib. Many owners ran their halliards aft to the cockpit, after they bought their boats. The jib halliard might be cleated there, instead of being cleated on the mast.
I have two halyards - one for the main, and a second that should be used for the gib, but instead it is used to hoist the sailcover for the gib when furled..
I think Gary's right. I have a CDI furler and the halyard is indeed internal to the foil in the slot opposite the sail. It should have a length of line about 2-3 feet long exposed. You need to be sure to attach a messenger line to this halyard so that when you lower the sail, you won't lose the line to the top of the halyard. Once you detach the halyard from the furler drum, simply slide the sail down. By the way, a little SailKote helps with hoisting it back up.
I second John's opinion - pix would help make it certain. Best advice is go slow, it's a bit of a puzzle, but keep a sharp eye as you haul the gib down and you'll suss it out.
If it is a CDI you need to attach a messenger line at the bottom so that you can raise the sail when you put it back on. Also take a camera and photograph the setup. That way you will have a record. I also use a permanent magic marker to identify the bottom and top of the sail. Next season you do not want to put it up and take it down because it is installed wrong. Also mark the lines with marker so you know where they attached to the sail. That way the length of the line will be the same.
I have an "ANTIQUE" CDI furler,(circa 1983),(a model 3B), and when taking down the jib I sew together the internal halyard to a messenger halyard of the same length BUTT TO BUTT. Later messengers from CDI popped out of the furler and didn't work. Before using this arrangement I spray all lines with SAILKOTE lube, just to make the job less laborious. Save the messenger and label it before stowing.
I had good results by de-coring about a foot of the internal halyard, pulling it out of the slot and tying a bowline to attach a messanger to. Not sure it's the recommended method, but it works great.
BOB... the messenger that CDI sent me sounds like what you've accomplished by partially decoring your halyard except the one they sent me kept popping out of the groove. I mentioned this to the folks at CDI and they had no solution for me other than returning their product for a full reimbursement. Not bad BUT, not good either. I continue to butt stitch the messenger to the halyard and save the messenger for the next go-round.
