Ronstan's range of continuous line furling systems puts great performance and reliability within the reach of cruising and racing sailors alike. This AL6061 anodised aluminium fairlead can replace the shackle on the furler to provide a 2:1 purchase on the furler attachment. The tack line is dead ended at the deck or end of the bowsprit, runs up around the 2:1 fairlead, back down to a block, and back along the deck to a rope clutch. This configuration is a popular way of adjusting tension in the torsion rope, and hence the luff of the sail.
