Low-friction efficiency for easy furling and reefing • Multiple rows of Torlon ® ball bearings in high-load areas minimize friction. • Stacked bearing races evenly distribute radial and thrust loads; drum and halyard swivel turn freely under load. • Foils rotate around headstay so headstay load is isolated from the furling unit for easy furling. • Large inner spool diameter increases mechanical advantage for powerful reefing and furling. Stands up to sun, salt, and time • Aluminum line guard, torque tube, and swivels deep- saturation hardcoat-anodized, UV-stabilized for durability. • Line guard polyurethane-coated for wear protection. • Specially formulated low-stretch black line is abrasion and UV-resistant; standard on units 0, 1, 2. • Aerodynamic (MKIV) and round (MKIV Ocean), foils handle extreme reefing loads. • Triple-interlock foil joints withstand years of torque loading: foil connectors geometric shape interlocks with foil; secures with syringe-injected adhesive; screws provide final lock.
