Facnor has designed a solution to handle your sail comfortably from the cockpit by just pulling the continuous furling line. This operation will make the drum and then the Facnor anti-twist luff rope rotate. The luff rope by Facnor transmits the rotation to the central furling rope. This will make the luff of the asymmetric Spinnaker furl from the center preventing twists that may come from use of the furler. At Mauri Pro Sailing we stock anti twist luff rope of different sizes for each size of boat from 9mm to 16mm. If you have any question, please contact us.
