2 Carbo Racing Foil The engineering resins in these strong, lightweight head foils offer significant advancements over the weaker PVC materials used by other manufacturers. The low-friction twin headsail grooves are ultra-smooth, allowing hoists, douses, and headsail changes to be easily and efficiently executed. Impact resistance is unmatched, with far less foil damage from loaded spinnaker poles, especially in cold weather. Heat has little effect on stiffness. Foils are UV protected and easy for the trimmer to see. For mast-up installation, simply uncoil the foil and snap onto the stay. Aluminum Chafe Guard An aluminum chafe guard keeps spinnaker sheets from damaging the foil during high-speed jibes. Testing shows this guard weighs the same as aramid fiber or composite, and is impervious to wear, unlike UHMW plastic tape which wears away quickly. A Harken chafe guard is included free with the purchase of a 7000, 7001, or 7002 kit. Trim cap Feeder for smooth hoists: Funnel-shaped stainless feeder smoothly guides boltrope into head foil for fast hoists. Prefeeder: Hardcoat-anodized, PTFE-coated aluminum rollers spin freely on low-friction bushings. Kit includes prefeeder.

3 Small Boat Furling Small Boat Furlers Harken Small Boat furling systems allow the trailerable cruising or dinghy sailor to set and furl the jib from the cockpit. Drums and halyard swivels feature multiple stacked races of Delrin or Torlon bearings for smooth rotation under load. Small Boat units are for furling only, not reefing. Upper swivel Hoistable swivel Halyard Hoistable Halyard Swivels An optional hoistable ball bearing halyard swivel can be installed on the headstay so the sail can be raised or lowered without removing the headstay. Swivels are independent of the headstay, which allows the luff to be tensioned separately from the mast rake. Hoistable swivels work along with your standard Harken Small Boat furler. Unfurl Furl The high-load Small Boat furler with hoistable halyard is available as a kit. Use for: 434 Dinghies under 4.9 m (16 ft) 435 Dinghies to 6.1 m (20 ft) Catamarans to 5.5 m (18 ft) 436 Cruising boats to 7.6 m (25 ft) Catamarans to 7 m (23 ft) Delrin is a registered trademark of E.

4 Small Boat Underdeck Furling Underdeck Furlers Small Boat underdeck furling units are ideal for sportboats and daysailers from 4.8 m to 9 m (16 to 30 ft). The drum is located beneath the deck, lowering the tack height for maximized sail area. The single through-deck ball joint provides a low-profile, nearly watertight system that aligns the spool to the headstay. Like all Small Boat furlers, the underdeck furler is for furling only, not reefing. Hoistable Swivels An optional hoistable ball bearing halyard swivel can be installed on your headstay so you can raise or lower the sail without removing the headstay. Swivels are independent of the headstay, allowing you to tension the luff separately from the mast rake. Hoistable swivels work along with your standard Harken Small Boat furler. Tack Adapter Tangs Stainless steel tack adapter tangs are used to adapt clevis pin diameters on headstays to the standard clevis pin size that comes on the Harken unit.

5 Spinnaker Staysail & Gennaker Furling Spinnaker Staysail Furled staysails are easy to hoist rolled and can be deployed or doused from the cockpit. In marginal conditions the sail can be struck instantly without changing the trim of the boat. Multiple stacked races of Torlon ball bearings ensure smooth operation under load. Systems include a lower drum with snap shackle, fairlead and Cam-Matic cleats, and an upper swivel with provision for halyard attachment. Gennaker Furling Gennaker furling was developed for large singlehanded boats and huge oceangoing multihulls. The drum unit features a fairlead, while the upper swivel is designed for direct halyard attachment. Custom designs are available for larger boats. Screecher Furling Use screecher furling systems on multihulls up to 9.60 m (32 ft) and easily driven sport boats. Perfect for jib reaching, screechers are set on the bowsprit. They are often carried upwind in light to moderate conditions and used as storm spinnakers when it s blowing. Systems are sized to handle loads of 2:1 halyards. Multiple stacked races of Torlon ball bearings ensure smooth rotation under load. Fairleads allow the furling line to lead aft to the cockpit. Multiple stacked races of Torlon ball bearings roll easily under load. Torlon is a registered trademark of Solvay Advanced Polymers.

6 Ordering Furling 1. Choose furler type The table below is based on sailing style and approximate boat size. This table is only a guideline. Do not use it to determine unit size. Size is based on the headstay and clevis pin diameters listed on unit pages. Comparison Chart MKIV Racers/performance cruisers ESP Cruisers Note: Typical boat lengths are listed as a guideline but are not the determining factor. Check with Harken if your length varies. Typical boat lengths Unit 0: m (22 30 ft) Unit 1: m (28 36 ft) Unit 2: m (35 46 ft) Unit 3: m (45 60 ft) Unit 4: m (65 80 ft) Unit 0: m (20 28 ft) Unit 1: m (26 35 ft) Unit 2: m (34 46 ft) Unit 3: m (45 61 ft) Foils Halyard and tack swivel Drum Line Double-groove Air foil Stainless steel feeder Independent swivels for improved sail shape Removable split drum for racing Included on Units 0, 1, 2 Single-groove round foil Stainless steel feeder Fixed Fixed Not included 2. Determine unit size Size is based on the headstay and clevis pin diameters listed on unit pages. Choose between unit sizes when diameters are shared by considering stay length and typical boat size recommendations. Contact Harken if you have any questions. 3. Determine if additional foils needed Use the I and J measurements to determine the length of the headstay. If the existing headstay is longer than the standard length listed under Headstay Length on unit pages, order additional foils and connectors. In some cases one or two extra foils and connectors may be necessary. 4. Determine toggle, link plate, or leg kit Use short toggle (MKIV) or short leg kits (ESP) for maximum luff length. For ESP, use long or medium leg kits to accommodate a turnbuckle or to clear an anchor. 5. Choose lead block kit and accessories, ESP - order line Harken recommends equipping every furling system with a ratchet lead block kit. Other parts on the Furling Accessories page ( ) include equipment for halyard management and racing hardware for faster sail changes. Order line for ESP furlers. 6. Prepare sail and headstay Have a luff tape added to your genoa. Match the sail length to the stay length minus the height of the halyard swivel and lower unit. See sizing information on page 171. All MKIV and those ESP furlers with long or medium leg kits install over the existing turnbuckle. The turnbuckle is accessible for adjustment by raising the drum. See the MKIV & ESP Toggle & Rigging Options on page 182 to determine toggle and rigging requirements. Some headstays will require cutting and shortening to fit Harken toggle. Sometimes only the lower threaded turnbuckle fitting needs changing. Check with a professional rigger on stay condition before reusing stay. For all units, rod rigging requires a Harken rod adapter stud. It must be cut and coldheaded by an authorized rod service center. 7.

8 MKIV Jib Reefing & Furling 1 FOR RACING AND PERFORMANCE CRUISING SAILORS MKIV furling systems are strong, lightweight and aerodynamic, with the performance and features Harken is known for. Longevity, ease of use, and simplicity of installation are crucial components of the design. These free-rolling furlers make all the difference in headsail control by allowing racers and cruisers to quickly furl and reef from the safety of the cockpit, while maintaining great sail shape and optimal speed DETAILS MAKE THE DIFFERENCE EASY REEFING AND FURLING Multiple rows of large-diameter Torlon ball bearings used in high-load areas to minimize friction for easy reefing and furling; require no lubrication or isolating seals. MORE FURLING POWER Large inner spool diameter increases mechanical advantage for powerful reefing and furling. Smaller outside dimension allows unit to fit narrow bows or belowdeck. Unit rotates around rod or wire headstay so furling bearings do not carry the headstay load for easy furling. LONG-LASTING PROTECTIVE FINISH Aluminum line guard, torque tube, and swivels are deepsaturation hardcoat-anodized for no-fade UV-stabilization, strength, and durability. The hardcoat-anodized line guard is urethane-coated for additional corrosion protection. Specially formulated low-stretch black line is abrasionand UV-resistant; standard on units 0, 1, and 2. Torlon is a registered trademark of Solvay Advanced Polymers. Sta-Lok is a registered trademark of Sta-Lok Terminals, Ltd. DO NOT use Harken equipment for human suspension. 1. 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. 2. 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. 3. Easy-to-Assemble Foils C-shaped open connectors with low-friction plastic isolators slip onto the headstay wire and into foil for easy installation. 4. Drum Installs Over Existing Turnbuckle Units are adaptable to a variety of rigging options for easy installation. Harken toggle assembly accepts standard turnbuckle using swage, rod, 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. 5. Stainless Steel Feeder Stainless steel feeder allows fast singlehanded hoist and quick sail changes. 6. Removable Split Drum Line guard and spool come off easily for racing. 7. Double Foil Grooves for Racing Aerodynamic aluminum Air foils handle extreme reefing loads. Double foil grooves allow fast hoists, douses, and sail changes

11 MKIV Underdeck Jib Reefing & Furling FOR PERFORMANCE RACING AND CRUISING SAILORS Harken s MKIV Underdeck furling is the perfect solution for performance racers and cruisers who 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. 1 Unit 0 2 Unit 1 and larger DETAILS MAKE THE DIFFERENCE EASY REEFING AND FURLING Ball bearings between the center hub and deck bearing provide low-friction furling. DURABLE MATERIALS AND CONSTRUCTION Size 1 and larger: Aluminum line guard, torque tube, and swivels are deep-saturation hardcoat-anodized for no-fade UV-stabilization and durability. The hardcoatanodized line guard is urethane-coated for additional corrosion protection. 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. 1. Torque Tube Houses Full-Length Turnbuckle The torque tube houses a full-length turnbuckle for optimal mast rake and tension adjustment. 2. Articulating Torque Tube Attachment A torque tube universal joint on Units 1, 2, and 3 provides a high-strength universal connection to allow ample headstay sag when sailing downwind. The Unit 0 features an articulating ball joint, eliminating the universal joint and toggle to reduce weight and to simplify maintenance. 3. Belowdeck Drum Fits Narrow Bows The small outside drum diameter lets unit fit inside narrow bows. 4.

13 ESP Jib Reefing & Furling 1 FOR CRUISING SAILORS The ESP is designed for the cruiser looking for an easy-to-assemble furler with an elegant design. Install a Harken ESP furler and trim safely from the cockpit when it blows; unfurl instead of motoring when it s light, for a great day of sailing. 2 DETAILS MAKE THE DIFFERENCE 3 EASY ASSEMBLY AND INSTALLATION Foils slip over the standard marine eye and headstay wire for easy installation. The adjustable bottom foil fine-tunes the system length. Shackles at the tack and head attach the sail to the furler, with sail shape controlled by halyard tension. There is no need to cut the wire during installation. STANDS UP TO ELEMENTS Spool is made from Hard Lube-anodized aluminum. Cover, flange, and guard are molded from glass-reinforced polymers for high strength. Foils are clear-anodized for durability. The stainless steel sail feeder is strong and durable. LONG, MEDIUM, OR SHORT LEG KITS TO ADJUST DRUM HEIGHT Medium and long leg kits raise the drum to clear the anchor, reduce sail chafe, and increase visibility. Removable clamp screws allow legs to pivot out of the way for easy access to the turnbuckle. Choose the long leg kit when using a turnbuckle with swage, Norseman or Sta-Lok terminals. Medium leg kits work with a variety of turnbuckles; refer to height chart on unit pages. Choose the short leg kit when the furler attaches directly to a marine eye at the bottom of the stay. Short legs allow the sail to be closer to the deck. OPTIONS An optional halyard deflector, installed above the foil, prevents the jib halyard and other halyards (such as a spinnaker or additional jib halyards) from wrapping around the foil when furling. Strong, lightweight stanchion-mounted blocks are offered to lead line aft for safe furling from the cockpit. Line not included. 1. Single-Groove Round Foil Round foil profile withstands extreme reefing loads for secure furling. Rolls more easily than flat foil shapes. 2. Strong Foil Joints Tough foil joints withstand years of torque loading. Connector interlocks with foil and secures with screws. No extra adhesive needed for a secure lock. 3. Long, Medium, or Short Leg Kits Choose long or medium leg kits for furlers with turnbuckles. Check turnbuckle length to determine which leg kit length is required. Choose short leg kits when furler attaches directly to a marine eye fitted to the end of the stay. DO NOT use Harken equipment for human suspension.

16 Electric Jib Reefing & Furling PUSH-BUTTON SAIL CONTROL Designed for large cruising boats, electric furling is a headsail system that helps you get the most out of your boat, while letting you comfortably reef, furl, and set sails from the cockpit with the push of a button DETAILS MAKE THE DIFFERENCE HIGH-STRENGTH MATERIALS, SCULPTED DESIGN The torque tube, motor, and gear housing are deep-saturation hardcoat-anodized, UV-stabilized aluminum. The sculpted gearbox and streamlined motor housing are sealed with high quality lip seals and O rings. The motor mounts vertically into pulpits, clearing anchor tackle and providing low windage. HIGH-TORQUE, HIGH-EFFICIENCY MOTOR The motor is a permanent magnet design and features high torque and low power consumption. Inside, the hardened steel gears are permanently lubricated. The reversible drive uses a high-reduction worm gear set to prevent reefed sails from unfurling under load. 1. Strong Foil Joints Tough triple-interlock foil joints withstand years of torque loading or 24-Volt Systems Available in 12 or 24 volts; switches and 12- or 24-volt control box and circuit breaker included. 3. Emergency Manual Operation Use supplied crank handle or cordless drill adapter. 4. Scratch-Resistant Link Plates Stainless steel link plates fit over standard turnbuckle, resist scratches, and can be easily repolished. EASY TO INSTALL OR UPGRADE C-shaped connectors slip over the headstay without feeding wire through the connector. The lower unit fits over the existing turnbuckle allowing easy length adjustment.

19 MKIV Hydraulic Jib Reefing and Furling 1 PUSH-BUTTON SAIL CONTROL Harken MKIV Hydraulic Jib Reefing and Furling systems allow sails to be reefed, furled, or set with the touch of a button. The unit s compact size brings the sail s tack close to the deck for smoother furling and improved sail shape. Both tack and head have independent swivels, improving sail shape when partially reefed. MKIV hydraulic furlers are used on cruisers and performance cruisers with headstays up to -320 rod or equivalent fiber stay. Worldwide parts and service. 2 DETAILS MAKE THE DIFFERENCE STANDARD TRANSMISSION REDUCES FRICTION AND PRESSURE LOSS A standard transmission, rather than a diverter valve, engages and disengages the powered and manual gear drive. Reduces mechanical friction and hydraulic pressure loss for efficient power and manual operation. The motor has no case drain line, reducing the number of hoses plumbed on the boat from three to two. Worm gear drive prevents backwinding and unloads the hydraulic motor when reefed. LONG-LASTING MATERIALS Torque tube, motor, and gear housing are hardcoatanodized aluminum for long-term wear and UVstabilized to withstand the effects of saltwater and sun. Aluminum foils are clear-anodized. Large-diameter Torlon ball bearings in halyard and tack swivel minimize friction, require no lubrication or isolating seals. Hardened steel gears and bearings are permanently lubricated in an oil bath for minimal maintenance. 1. Easy Headstay Adjustment Over-the-turnbuckle system allows easy headstay adjustment. The lower toggle assembly fixes at 90-degree intervals to accept any chainplate direction. 2. Optional Hydraulic Cylinder An optional hydraulic cylinder installed below the unit adjusts the headstay so luff tension remains constant. This prevents halyard and tack attachments from overloading when the headstay is adjusted. 3. Improved Sail Shape Independent head and tack swivels improve sail shape when reefed. Hard and Soft Attachments Unit 3 uses a hard shackle; halyard and tack swivels on Units 4 and larger are lashed on with Spectra line using a patented system to evenly distribute loads and eliminate heavy shackles. 4. Double Foil Grooves Aerodynamic aluminum sections handle extreme reefing loads. Double luff grooves allow fast hoists, douses, and sail changes. 5.

24 Furling Accessories Carbo Furling Lead Block Assemblies Harken recommends equipping every system with Carbo lead blocks for safe furling from the cockpit. The 7404 kit s lightweight, UV-stabilized Carbo blocks run exclusively on ball bearings for fast trimming under any load. A 7402 ratchet maintains tension when spooling so the unit furls smoothly and easily. The 7403 outboard assembly allows the furling line to travel outboard of the stanchion to keep the sidedeck clear. Block mounts with a strong four-screw clamp without removing the stanchion or lifelines. Use the 7401 block on the bow pulpit as an inboard lead. Use the 7405 as an inboard lead for two lines, for continuous line furlers, or cutter-rigged boats with two furlers. 7401, 7402, and 7405 have ball-and-socket bases to align blocks for smooth leads aft. The 7404 lead block kit provides a complete system for most boats. Stanchion Mount Bases The 061 bases for Carbo and Classic blocks lead furling line inside the stanchion. Halyard Restrainers A halyard restrainer keeps the halyard against the mast. This provides a better angle to the halyard swivel and prevents it from wrapping around the foil. Stainless steel brackets feature hardcoat-anodized aluminum sheaves that accommodate both wire and rope. Halyard Deflector A halyard deflector prevents the jib halyard and other halyards (such as a spinnaker or additional jib halyards) from wrapping around the foil. Prefeeders and Snap Shackles Prefeeders and snap shackles facilitate fast sail changes. The 7006 prefeeder features hardcoat-anodized rollers with low-friction bushings. The 7403 outboard assembly allows furling line to travel outboard of the stanchion to keep the sidedeck clear , ,
