Improved sail shape and boat control
• Independent halyard and tack swivels furl sail center before head and tack 
 for improved sail shape when reefed. 
• Lightweight aluminum halyard swivel saves weight aloft to reduce pitching 
 and heeling.
• Tack sits at deck level, lowering the tack height for maximized sail area.
• The torque tube houses a full-length turnbuckle for optimal mast rake 
 and tension adjustment.
• Units 1, 2, 3: High-strength universal joints articulate, allowing ample 
 headstay sag when sailing downwind.
• Unit 0: Articulating ball joint eliminates universal joint to reduce weight, 
 simplify maintenance.
Fast hoists, douses, reefs, 
and sail changes
• Precision-extruded, double-groove 
 Air foils for smooth sail handling and 
 fast sail changes.
• Stainless steel feeder allows fast 
 singlehanded hoist and sail changes.
Designed for easy installation
• Units 1, 2, 3: Self-locking threaded 
 height adjuster for correct fit between 
 chainplate and deck.
• Unit 0: Does not require height 
 adjuster; furler and headstay 
 independent of each other 
 allowing flexible installation options.
• Torque tube fits over existing 
 turnbuckle allowing easy length 
 adjustment. Hub assembly toggle 
 accepts standard turnbuckle using 
 swage, rod, Norseman, or STA-LOK® 
 terminals.
Belowdeck drum fits narrow bows
• Small outside drum diameter.
Easy to maintain
