Manufacturer part #:7410.11 Underdeck Furling System
Harken's MKIV Underdeck Furling is the perfect solution for performance racers and cruisers that want an aerodynamic system with a minimal amount of equipment above deck. The drum is located beneath the deck, lowering the tack height for maximized sail area.
Easy Reefing and Furling
Ball bearings between the center hub and deck bearing provide low-friction furling.
Durable Materials and Construction
The threaded height adjuster uses dissimilar metals (stainless steel and bronze) to prevent galling. Size 0: A one-piece integrated deck bearing and line guard provides durability and corrosion resistance.
Easy to Maintain
The furler can be flushed clean with detergent water like traditional furling.
The through-deck bearing minimizes water seepage into the underdeck compartment.
Torque Tube Houses
Full-Length Turnbuckle The torque tube houses a full-length turnbuckle for optimal mast rake and tension adjustment.
Articulating T orque Tube Attachment
The Unit 0 features an articulating ball joint, eliminating the universal joint and toggle to reduce weight and to simplify maintenance.
Belowdeck Drum Fits Narrow Bows
The small outside drum diameter lets unit fit inside narrow bows.
Installation Options
The Unit 0 does not need a height adjuster. The furler and headstay are independent of each other, allowing flexible installation options.
