MKIV Jib Reefing and Furling Typical boat length 22 to 30 ft. ft. 1. Free-Rolling Ball Bearings: Multiple rows of large-diameter Torlon? ball bearings in high load areas of the halyard swivel and drum minimize friction for smooth furling; Require no lubrication or isolating seals. 2. Strong Foil Joints: Tough triple-interlock foil joints withstand years of torque loading. Connector?s geometric shape interlocks to foil and secures with a syringe-injected adhesive into an engineered channel. Screws provide final lock. 3. Easy to Assemble Foils: C-shaped open connectors with low-friction plastic isolators slip onto the headstay wire and into foil for easy installation. 4. Drum Installs Over Existing Turnbuckle: Units are adaptable to a variety of rigging options for easy installation. Harken toggle assembly accepts standard turnbuckle using swage, rod, Norseman? or Sta-Lok? terminals. Toggle flips for fork or tang chainplate installation. A single stainless steel clevis pin provides access to the turnbuckle for adjustment. 5. Stainless Steel Feeder: Stainless steel feeder allows fast singlehanded hoist and quick sail changes. 6. Removable Split Drum: Line guard and spool come off easily for racing. 7. Double Foil Grooves for Racing: Aerodynamic aluminum Air Foils? handle extreme reefing loads. Double foil grooves allow fast hoists, douses and sail changes. 8. Improved Sail Shape: Independent swivels furl sail center before head and tack for improved sail shape and smoother furling.
