Furl or set your jib from your cockpit Harken small boat furlers allow the sail to be set and furled from the cockpit, a critical convenience in many racing dinghies and trailerable sailboats. These systems, now sold as drum and swivel kits, are for roller furling, not for reefing. Constructed of Hardkote anodized Teflon-impregnated aluminum, they feature multiple stacked races of Delrin or Torlon ball bearings for smooth rotation under load. The jib's luff wire must be properly seized to the sail, since it carries most of the headstay load. You must supply the drum furling line in the diameters shown in the chart.Key Features: Includes drum and swivel Line not included
