The last 2 times I've been out sailing my roller furler has jammed the last 2 or 3 revolutions when pulling out the jib. It furls fine, the lines aren't jammed and after I tack 2 or 3 times it comes all the way out I've looked and can't determine the reason and was wondering if anyone else has any ideas about what to look for.
Hood roller furler

Hi Hugh, what model boat and it sounds...
as though you have a double line furler? The Hood double line furler on our 1991 model boat has never jammed whether winding or unwinding. Have you made a close inspection of the entire system for broken or misaligned parts? There is a plastic sheet splitter (not sure of the correct nomenclature) that is supposed to peel the sheet away from the drum as it spins. Sometimes they will break causing the drum to jam. Just a thought. Terry

It isn't clear
whether you have a line jam in the drum when unfurling, or some other mechanical problem causing the jam. The first thing to check is whether you have too much line on the drum when the sail is unfurled. With a big headsail, there may not be enough space for the line to coil on the drum. If so, try unloading it. Most line jams are caused by the furling line overwrapping a line below it on the drum, or by not having the right angle of the furling line as it exits the drum to the first fairlead. YOu may want to try to keeping moderate tension on the furling line as you unfurl the sail with a sheet to ensure the line is furling cleanly on your drum. Same thing when furling up the sail. Also, it may help to experiment with changing the angle of the line existing the drum. Finally, on some Hood furlers, Hood recommends de-coring the furling line for about the first 30 feet or so. This results in just using the cover (plenty strong enough)on the drum and it will wind/unwind easier as it is flat rather than round. Also, if neither of these things solve the problem, try looking up at the upper swivel when you are unfurling the sail to make sure you do not have any kind of halyard wrap or similar issue. Also, this will tell you if the upper part of the sail is unfurling in tandem with the lower part of the sail. An upper swivel that needs new bearings or grease could cause the type of problem you describe. Good luck with this.

Warren?
He may not have enough of the line "cored" at the head of the line. "Coring" means to remove the inner core of the line. Thus leaving only a braided outer sheath. Hood recommends that 15' be cored, but that may be for a smaller headsail, as the stock Hunter's have. If you have a large Genoa (greater than 100%-110%), I'd advise that you call Hood for a recommendation before taking any action.

top bearing
Hello Hugh, Before looking anywhere else, I would go up the mast and check if the Top Bearing at the extreme top of the extrusion is broken. Actually they call this a bearing but in fact it is only 2, 1/2 round plastic parts that keep the metal stay centered in the aluminium extrusion, no moving part. The part is worth 26$ (Pompanette.com) and is often the source of blocking problems on this unit. I own a 35.5 and had the problem as 2 other 35.5 in my area. This part can be change in 10 minutes with the extrusion/stay assembly in place. The symptoms you describe are exactly what is happening when 1/2 of the top bearing is gone. I would also investigate in the anchor well to make sure that the 2 parts of the drum assembly are not too close together. There should be 1/16" between the 2 parts. This can be adjusted by lowering the bottom portion of the drum using the Allen screw under the furling unit. It sure is worth the trip up the mast. Good luck PS I am including the Web of pompanette http://www.pompanette.com with the drawing. Bearing is part number 1
