198 Q5 Quintessential, Yachting Developments © Chris Lewis Powerful performance packed into a compact, slim profile makes our hydraulic headsail furlers the ultimate in push- button sail control. Perfect for cruisers and performance cruisers, these free-rolling systems fit wire sizes from 11 - 25 mm (7/16" - 1"); rod from -22 to -115 or equivalent fiber stays. Parts and service are available around the world. 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; halyard swivel turns freely under load. MKIV HYDRAULIC JIB REEFING & FURLING DO NOT use Harken equipment for human suspension unless product is specifically certified and labeled for such use. Foil joints Standard transmission reduces mechanical friction and pressure loss • Engages/disengages the motor’s powered and manual gear drive for efficient operation. • Worm gear drive prevents backwinding; unloads hydraulic motor when reefed. High-strength, lightweight • Hardcoat-anodized, UV-stabilized aluminum torque tube, motor, and gear housing. • Aerodynamic, clear-anodized aluminum Air 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.
