I am having a significant problem raising my genoa on my CDI FF2 furler. It lowers just fine. After lowering the sail I sighted along the edge of the luff extrusion and found a kink about 12' up the extrusion. There is a second smaller kink further up the extrusion. Evidently I have an older CDI furler as the extrusion is aluminum and not pvc. It appears that most of the on-line information concerns the pvc extrusions and putting the kinked extrusion in a tube and letting it sit in the sun for a couple of weeks. I wonder if this would work for aluminum. I checked for replacements and there are pvc replacement extrusions for around $250. Has anyone successfully straightened an aluminum CDI furler luff extrusion? If so, how?.
