Sounds like the furling line through the fairleads "routing" isn't the problem..... And the furling line is not rubbing on the stainless steel housing? It should be positioned in the center of the opening,(it's adjustable from below). Is the big stainless steel washer,(which serves as the bearing surface), installed? One reason I questioned the fore-stay is that I've had several boats now that didn't have the toggle installed on the top of the fore-stay,(as recommented by CDI), and the fore-stay had a kink, which caused friction for the plastic luff extrusion to bind as it tries to revolve around the forestay. Most folks don't understand the importance of the toggle, and don't want to have a new forestay fabricated when they have a perfectly good stock forestay from the factory. Is the plastic luff extrusion is perfectly straight? It easily bends and doesn't take long to develope a memory of the bend, which I've never been able to remove, even after sitting on a level surface in the hot California sun for months. The bend that the factory causes when they roll the extrusion will fall out after several days to a week in the sun. Which brings up the point, you said you recently installed it, would the extrusion lay perfectly flat on the driveway before it was installed, or was it un-rolled and slid on the forestay? Any bend will cause friction to bind the plastic luff extrusion on the forestay. I recently had one boat I refurbished that this binding was so severe that it twisted the forestay cable so bad it broke 6 of the 19 strands,(another reason there needs to be a toggle on the top end of the forestay). Don't forget, there is a lot more leverage un-furling, plus the wind to help you. Hope that helps.
