MKIII JIB REEFING & FURLING

MKIII OFFSHORE BOATS 22' - 100'+ (7 m - 30 m+) JIB REEFING & FURLING MKIII jib reefing and furling systems are modern and elegantly styled. Constant refinements to these dependable, raceproven furlers have kept Harken the leader. Today, they re aboard more than 50,000 ocean-going yachts, coastal cruisers, and around-the-world racers. They feature strong, light Air Foil extrusions and large-diameter drums for easy furling. Free-running Torlon ball bearings require no lubrication or seals and need minimal maintenance. Independent head and tack swivels shape the sails; tripleinterlock foil joints provide years of trouble-free reefing. BUILT-IN TURNBUCKLE to make installation and mast tuning easy. Designed to handle side loads, the turnbuckle s nickel-plated silicon bronze and stainless steel construction is seize resistant. TORLON BALL BEARINGS require no lubrication or isolating seals. The multiple races and large diameter Torlon bearings minimize friction even under extreme reefing loads. STAINLESS STEEL FEEDERS are shaped and finished for quick single-handed hoisting and fast sail changes. Molded lightweight prefeeder attach- EXISTING ROD OR WIRE HEADSTAY easily accepts foils and maintains the integrity of your rig. TAPERED TORQUE TUBE minimizes sail stretch and wrinkles when reefing or furling. LARGE INNER SPOOL DIAMETER increases mechanical advantage, to give more power for reefing and furling. MOLDED SPLIT DRUM on all units for easy race conversion. Spool and cover are lightweight, corrosion-free, and less susceptible to chain and anchor damage. PRESSURE-CAST ALUUM LINE GUARD provides easy line access. Line guard removes quickly and resists anchor dents. Deep penetrating black Hardkote anodizing adds years of corrosion resistance. NEW ENGLAND STA-SET black line is low stretch, abrasion and UV resistant, and enhances the monochromatic elegance of the product. Standard on units to 2.5.

AIR SWIVELS are light and small to reduce windage and weight aloft. They turn freely on computer-designed bearing races. BEARING SHIELDS protect Air Swivel and tack bearings from UV and dirt. BEARING SYSTEMS handle multi-directional loading. Multiple races evenly distribute radial and thrust loads to balls. Foils turn freely under halyard loads. INDEPENDENT SWIVELS furl the center of the sail before the head and tack to reduce draft for a better sail shape. LIGHTWEIGHT AERODYNAMIC FOILS handle extreme reefing loads and maintain proper airflow to your genoa. ADAPTS TO SWAGE, ROD, NORSEMAN OR STA-LOK TERALS For easy installation, use our long swage stud with existing wire headstay. Norseman or Sta-Lok fittings are favored for extended cruising in tropical saltwater areas. Rod terminals adapt the furlers to low stretch rod. FOIL CONNECTORS are Hardkoteanodized with Teflon impregnation to isolate materials, reduce connector wear and lubricate the foil system. The circular shape reduces weight and foil size. TRIPLE-INTERLOCK FOIL JOINTS withstand years of torque loading. Connectors are shaped to match extrusions; screws secure the connectors; adhesive removes point loading from the screws. RACING All MKIII furling systems convert to racing. Simply remove the drum and lower the halyard swivel to clear the twin groove foil for sail changes. The Air Foil -shaped extrusion gives you racing performance round foils can never offer. Foil tops are clean and completely cover the headstay for maximum luff lengths. INSTALLATION Harken furling units are designed for owner installation, and can be assembled using simple hand tools. Picture-book-style instruction manuals make assembly easy. MKIII jib reefing and furling systems are covered by a seven-year limited warranty. Expert service and parts are available from Harken s worldwide distributor and dealer network.

Furling Accessories Stanchion Mount Bases Stanchion mount bases provide an ideal attachment method for furling lead blocks. The ball joint socket accepts most Small Boat swivel blocks, including ratchet blocks. Bases fit all standard 7/8" and 1" (22 mm and 25 mm) pulpits and stanchions. Furling Lead Blocks Furling lead block kits include ball bearing blocks, Hexaratchets to provide proper drag on furling lines, stanchion mount bases, and cleats. Mount fixed leads on boats with bulwarks to keep sidedeck clear. Halyard Restrainers Harken offers two sizes of halyard restrainers. Each is a stainless steel bracket shaped to fit radiused spars. The Hardkote-anodized aluminum sheave is grooved for both wire and rope halyards and rides on Teflon - impregnated epoxy bearings. Halyard restrainers should not be used unless required. 319 DOUBLE LEADS are used on boats with continuous line furling or when leading multiple lines aft. 8 AND 9 FIXED LEADS mount on boats with bulwarks to keep furling line clear of sidedeck. THE 061 STANCHION MOUNT BASE is an ideal attachment method for furling lead blocks. The ball joint socket with rubber standup accepts single swivel blocks in Bullet, Big Bullet, 57mm Carbo, 2.25" plain or Ratchet. Base fits standard 7/8" and 1" (22 mm and 25 mm) pulpits and stanchions. 88 AND 885 SNAP SHACKLES are used for head and tack when changing sails often. Fit units through 2.5. THE 97 PREFEEDER mounts 1' (30 cm) below feeder to help raise sails. Standard on Harken furlers. 9 AND 95 HALYARD RESTRAINERS have removable Hardkote-anodized sheaves that are grooved for both wire and rope halyards. Sheaves spin on Teflon impregnated bearings. Use only when headstay is close to halyard sheave. 266 AND 267 LEAD BLOCK KITS include ball bearing blocks, stanchion mount bases, cleats, and Hexaratchet blocks to provide proper furling line drag.

WORLD S LEADER ON OVER 50,000 YACHTS, CRUISERS, AND RACERS 1. SMALL BOAT FURLING: Set and furl the jib from the cockpit on dinghies and trailerable catamarans under 20' (6 m). All systems require a jib with a luff wire seized to the sail. See Harken catalog. SPINNAKER STAYSAIL, GENNAKER & SCREECHER FURLING: Furled STAYSAILS easily hoist rolled and can be struck without changing the trim of the boat. GENNAKER furling is ideal for drifters and reachers on multihulls to 5' (1 m). Perfect for jib reaching, SCREECHERS are set on bowsprits for sport boat and multihulls to 32' (10 m). See Harken catalog. 2. UNIT 00AL JIB REEFING & FURLING: Designed for coastal cruisers 20' - 26' (6 m - 8 m). It uses aluminum Air Foil extrusion. 3. MKIII REEFING & FURLING: Reef and furl jibs on offshore boats from 22' - 100'+ (7 m - 30 m+). The units are designed to fit over existing rod or wire headstays. Features include a large-diameter drum for easy furling and deep-penetration black Hardkote anodizing for even more years of corrosion resistance. 1 2 3 5. CARBON REEFING & FURLING: Reduce weight high and forward by almost half. Foils, halyard swivel, and other major components are standard modulus carbon fiber to reduce pitching and heeling, and the amount of lead needed in the keel. Elegant UV resistant finish. Available for use with rod rigging starting at -12 and up. See Harken catalog. 5. HYDRAULIC REEFING & FURLING: Reef and furl with the touch of a button great for cruising boats 50' to 120'+ (15 m to 36 m+) with headstays as large as 1" (25 mm) wire or -115 (22.2 mm) rod. This is the only system that features an investment-cast, stainless steel gear housing, and a double-enveloping cone-drive worm gear to stop a reefed sail from unfurling under load. Available with carbon fiber components. See Harken catalog. 1251 E.
