The KSF furler includes all the advantages of Karver’s KF Furlers, but incorporates an independent swivel on the top of the drum that enables the sail to furl from the top to the bottom, using an anti-torsion rope like the Marlow ProDrive. Most spinnakers don’t even need to be retrofitted. The same furler can be used with your full inventory of sails—code sail, staysail or asymmetrical spinnaker. The tack line can be adjusted from the cockpit to fine-tune spinnaker position and shape.
