Hello, The original system is a Hood 810 LD (for line drive) 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 parts are eaealy available at pompanette.com
One other advise, I always unload the pressure in the sail by sailing downwind with the wind coming from + - 130 to 140 deg. when rolling the genoa. The genoa is protected by the main sail and It is very easy to furl this way. It is worth a try.
