- Halyard Swivel Turns Freely - Strong, lightweight halyard swivel reduces windage and weight aloft to minimize pitching and heeling. Stacked bearing races evenly distribute radial and thrust loads to ball bearings; foils turn freely under halyard loads. Independent halyard and tack swivels furl sail center before head and tack for improved sail shape and upwind pointing.
- 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.
- Easy to Assemble Foils - C-shaped open connectors with low-friction plastic isolators slip onto the headstay wire and into foil for easy installation.
- Drum Installs Over Existing Turnbuckle - Units are adaptable to a variety of rigging options for easy installation. Harken toggle assembly (a required separate purchase) accepts standard turnbuckle using swage, rod, or swageless "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.
- Stainless Steel Feeder - Stainless steel feeder allows fast, single-handed hoist and quick sail changes.
- Removable Split Drum - Line guard and spool come off easily for racing. (Line is included.)
- Double Foil Grooves for Racing - Aerodynamic aluminum "Air Foils" handle extreme reefing loads. Double foil grooves allow fast hoists, douses and sail changes.
